Battery Energy Density

What is Battery Energy Density?

Energy density is the measure of how much energy a battery contains in proportion to its weight. This measurement is typically presented in Watt-hours per kilogram (Wh/kg). A watt-hour is a measure of electrical energy that is equivalent to the consumption of one watt for one hour.

Power density is the measure of how quickly the energy can be delivered, rather than how much stored energy is available. Energy density is often confused with power density, so it is important to understand the distinction between the two.

Why Do You Need a Battery with High Energy Density?

To better understand lithium batteries, you should understand why a high energy density is a desirable trait in a battery.

A battery with high energy density has a longer battery run time in relation to the battery size. Alternately, a battery with high energy density can deliver the same amount of energy, but in a smaller footprint compared to a battery with lower energy density. This greatly expands the possibilities for battery applications.

In factory or warehouse settings, forklift batteries can weigh thousands of pounds. A lightweight battery for forklifts offers some advantages in safety and handling.

If the energy density of a battery is too high, it could present a safety issue. When there’s more active material packed into a cell, it increases the risk of a thermal event.

Which Type of Rechargeable Battery Has the Highest Energy Density?

There are several different types of rechargeable batteries with a variety of energy densities reflective of their internal chemistry.

• Energy density of Lead acid battery ranges between 30-50 Wh/kg
• Energy density of Nickel-cadmium battery ranges between 45-80 Wh/kg
• Energy density of Nickel-metal hydride battery ranges between 60-120 Wh/kg
• Energy density of Lithium-ion battery ranges between 50-260 Wh/kg

Types of Lithium-Ion Batteries and their Energy Density

Lithium-ion batteries are often lumped together as a group of batteries that all contain lithium, but their chemical composition can vary widely and with differing performance as a result.

Most lithium-ion battery types share a similar design of a cathode with aluminium backing, a carbon or graphite anode with copper backing, a separator, and electrolyte made of lithium salt in an organic solvent.

Manufacturers have experimented with the materials used on the cathode & anode. They have also varied the composition of the electrolyte. These differences are what causes lithium-ion batteries to vary in their energy density levels.

Now we’ll review the most popular lithium-ion battery chemistries, along with their respective energy densities, use cases, benefits, and drawbacks.

Industry Titans: Lithium Titanate (LTO) Batteries

An LTO battery is one of the oldest types of lithium-ion batteries and has an energy density on the lower side as lithium-ion batteries go, around 50-80 Wh/kg.

In these batteries, lithium titanate is used in the anode in place of carbon, which allows electrons to enter and exit the anode faster than in other types of lithium-ion batteries.

This structure allows the LTO batteries to charge much faster and handle high currents safely, but the low energy density makes them poorly suited for material handling equipment.

They tend to be more expensive and are typically used for electric vehicles, car audio applications and mobile medical devices.

High Energy, High Risk: Lithium Cobalt Oxide (LCO) Batteries

Lithium cobalt oxide batteries have a high energy density of 150-200 Wh/kg. Their cathode is made up of cobalt oxide with the typical carbon anode, with a layered structure that moves lithium-ions from anode to the cathode and back.

These types of batteries are popular for their high energy density and are typically used in cell phones, laptops, and most recently electric vehicles.

Cobalt is a very energy dense material, but it can be expensive. As demand increases for use in electric vehicles, it’s a rapidly depleting resource. In fact the world could face a cobalt supply shortage soon.

Cobalt is also highly volatile. Lithium-cobalt batteries can’t handle large currents because of the risk of overheating, which is a significant safety risk. LCO batteries have lower thermal stability, which means they are highly sensitive to higher operating temperatures and overcharging.

Performance with a Price: Lithium Nickel Manganese Cobalt Oxide (NMC) Batteries

Lithium nickel manganese cobalt oxide batteries also have a high energy density of 150-220 Wh/kg. They use cobalt in the cathode just like LCO batteries, but they also contain nickel and manganese to help add stability.

NMC batteries are used in most electric vehicles in production today but are also used for medical devices and e-bikes.

The secret to this battery’s success is its well-balanced chemistry; nickel is known to be energy-dense but unstable, just like cobalt, while manganese is more stable but also lower in energy density. The specific ratio of different elements varies by manufacturer, but the addition of nickel is typically intended to allow them to reduce the amount of expensive cobalt.

NMC batteries can handle larger charge currents and a greater range in temperature than LCO batteries. However, since the battery still contains cobalt, the cost is driven up due to market scarcity.

Affordable, Safe and Reliable: Lithium Iron Phosphate (LFP) Batteries

LFP batteries have a high energy density of 90-160 Wh/kg. While that is lower than some of the cobalt batteries, it is still among the highest of all the battery types.

LFP batteries use iron phosphate for the cathode and a graphite electrode combined with a metallic backing for the anode.

Lithium iron phosphate, or LiFePO4, is a naturally occurring mineral that is inexpensive, non-toxic and has good thermal stability with high energy density.

LFP batteries are ideal for heavy equipment and industrial environments because of their ability to withstand a lot of abuse and a wide range of temperatures. They have emerged as a new go-to option in forklifts and other heavy electric equipment that needs a high level of reliability and has historically relied on lead acid batteries.

All types of lithium-ion battery chemistries are unique. It is crucial to understand which lithium-ion chemistries are best suited for your application.

If you are searching for the best battery for your material handling equipment, a lithium iron phosphate battery is likely the best choice. Of course, for RC hobby or UAV drone, high energy density of lipo battery will give you the different fly experience, they offer the best balance between safety and performance.

Can I Fly My Drone in the Winter?

 You may have heard that there are restrictions when flying your drone in high temperatures, but did you know that it’s a similar case in low temperatures too?

We will explore some factors to consider if you plan on flying your drone in cold weather.

The impact of low temperatures on drones

Lower temperatures slow down the chemical reaction of LiPo Battery, thereby reducing battery capacity, increasing resistance, and shortening the flight time. Drone manufacturer DJI states on its website that the LiPo batteries that power their drones start draining at an increased rate at temperatures below 59℉ (15°C).

It’s important that users read the manuals for their drones before a flight.  The operator temperature of most drones is set at 32 to 104 ℉ (0 to 40°C), so you should avoid flying outside of this temperature range.

To fly a drone in low-temperature, you need to prepare in all aspects.

Measure

Before going out

Plan your day out beforehand and try to finish your flight as soon as possible before it gets too dark. See the weather forecast: if there’s snow, hail, or rain, reschedule your flight as these weather conditions can damage your equipment and drones and very likely cause a crash.

Ensure your batteries are fully charged and have spare ones on hand to switch out.

When going out

Limit direct exposure of your batteries to the cold air. Keep them in their gear or protective equipment instead of just in the trunk of your vehicle.

Take off

When launching your drone, raise the aircraft 10-20 feet from the ground and make it hover for 30-60 seconds. This can increase the temperature of the battery to achieve a warm-up effect. Some apps, such as the DJI GO, allow you to check and monitor the battery temperature.

Source: DJI

Focus on the battery’s voltage. You should keep the battery’s voltage indicator displayed on your monitor so you can keep track of it.

Check the components. In a cold environment, some parts, like propellers, become more fragile. Therefore, it is necessary to check them more diligently for cracks or damage. You can also consider replacing them with solid carbon fiber blades.

Avoid running out of capacity. Fly until the battery drops to 30-40% of its capacity, and then bring the drone back down. In order to prevent other unpredictable situations from happening, don’t drain your battery completely when flying.

Stop flying immediately if it starts to rain or snow.  Be careful because most drones are not waterproof. Moisture may short-circuit the motor and cause the drone or controller to malfunction.

For you

Don’t forget to keep yourself warm. It is best to wear gloves which can touch the screen because it will be very inconvenient to operate the device with cold and stiff hands.

Wear goggles. When flying in icy or snow-covered weather, your eyes may be damaged due to the greater light reflection. Goggles can avoid this problem.

Low temperature-resistant battery

You can also look at low temperature-resistant batteries, such as the LiPo batteries developed by Grepow, which achieves lower internal resistance and increase the discharge rate.

The lowest operating temperature is -58℉ (-50℃), which breaks the discharge limit of traditional lithium polymer batteries. These batteries can also be customized per the clients’ needs and product requirements. Go here to learn more about the discharge rate of these batteries at different temperatures.

If you’re aware of your surroundings and take things tips into account, you will be able to fly more smoothly in cold weather. Get ready to take off: the magnificent scenery is waiting for you.

What is the lithium battery balancing? | Battery Cell Balancing

 

Introduction

Generally, the battery balancing is a term used in drone/UAV and some RC models fields. It means that the voltage of each cell of the battery pack should be balanced. Also, the voltage difference of each cell is “voltage gap”, the voltage gap of each cell should not exceed too much. Therefore, we have to ensure that when each cell is being charged and discharged, the voltage rise and fall are within a balanced and acceptable range.

Consequences of using lithium battery without battery balancing

The batteries we usually use are single cells, like our mobile phone batteries, and when the battery pack you use is packed by multiple cells in series or in parallel, then you need to know about the battery balancing of the lithium battery.

Let’s take an example, imagine that our battery pack is like different reservoirs, the same as the water pressure of each reservoir thus the same output of each reservoir. If we cannot ensure the equal level of water pressure of each reservoir, it will lead to one pool is dry and the other pool is still full. However, their staff will not check the remaining capacity of each reservoir, then a single pool will be overcharged due to refilled water uniformly.

Battery Balancing Comparison

Battery cell balancing charging and discharge comparison

Taking the example of a reservoir to describe the battery may not be appropriate, but the principle is the same. We must ensure the voltage and capacity of each cell are at the same level, otherwise, the duration time and life of lithium battery will be discounted, the battery performance will also be declined.

The picture below shows that the voltage of every single cell on a 6S battery, the voltage gap is less than 0.01V, it just only 8mV.

6S lithium battery voltage gap testing (Source: Grepow)

Therefore, lithium battery balancing is one of the essential factors that determine battery quality. In the operating process, it will generate a bit voltage gap, but we could control that in an acceptable range thought battery balancing.

How to achieve the lithium battery balancing?

Battery Management System (BMS)

Generally, the battery itself cannot achieve battery balancing, so it could be achieved through Battery Management System (BMS). The battery manufacturer will integrate battery balancing function and other protection functions on this BMS board, such as charging over-voltage protection, SOC indicator, over-temperature alarm/protection, etc.

Lithium Battery Charger with Balancing Function

It also calls “Balance Battery Charger”, the charger is integrated the balancing function, it supports the different batteries with a different number of series (e.g. 1~6S). You charge the lithium batteries through this kind of battery charger can also achieve the balancing even your batteries are lack of BMS board.

Balance board

When you use a balance battery charger, you also have to connect the charge and your battery with the balance board, to choose the specific socket from the balance board, the following picture is a sample of a balance board.

Benefits of lithium battery balancing

As I mentioned before, maintain the voltage in an acceptable range, it can extends the battery’s operation time and battery life. It can reduce the cost of you replace a brand new lithium battery, and also increase the safety of battery use, so that your battery is in a more stable state.

Lithium-ion battery vs lithium polymer battery

 Nowadays, portability is considered to be a vital part of most of the electronics. This has given rise to the production of many new types of batteries. Some of them are good at one thing while others are good at other things. Some of them are very dangerous too. That is why there are rules for every type of battery for using, carrying, and transporting them.

Here we will discuss two of the most popular types of batteries in the world. This will be a comparison between the lithium-ion and lithium-polymer batteries according to their specifications and differences. In the end, we will also share information about transporting these batteries in planes.

Is a Lithium Polymer Battery a Lithium-ion Battery?

Due to the similarity in the names, many people are confused about this. No, these are not the same as the lithium-ion battery is a completely different thing from the lithium-polymer battery. There are many differences between these two types of batteries. These differences are discussed below.

Difference in Energy Density.

This is the greatest difference between these two batteries. Energy density is the charge that a battery can store according to its weight. The lithium-ion batteries are great in this because they have very good energy density that means that they can store huge amounts of power in them?

Whereas the lithium polymer batteries have a very lower energy density as compared to the lithium-ion batteries.

Difference in Cost.

Cost is another factor that sets these two different types of batteries apart. It is a very interesting fact that despite the lithium-ion batteries having a battery energy density, they are still cheaper. The lithium polymer batteries are usually 30% more expensive than lithium-ion batteries.

Difference in Weight and Structure.

In the field of structure of the batteries, the lithium polymer batteries are better. This is because they are very lightweight, and their enclosure is a little bit soft. Another factor is that these batteries can be constructed in a low-profile style. This increases their cost. On the other hand, the lithium-ion batteries are usually bigger and harder.

Difference in Security Features.

The security of a battery is a major concern for many producers and consumers. The lithium-ion batteries are prone to exploding in bad circumstances because the two different materials in these batteries can easily meet. The lithium polymer batteries are very safe as compared to lithium-ion batteries because their electrolyte is not as prone to leakage.

Difference in Lifespan.

The lifespan of lithium-ion is comparatively longer than that of the lithium polymer batteries. And there is no memory effect in the lithium-ion batteries as well. But the lithium-ion batteries lose their storage capacity with time.

Which is Better, Lithium-ion Battery or Lithium Polymer Battery?

This is another very popular regarding the lithium-ion and lithium polymer batteries. Both of them are very popular and this is what makes people get confused. But none of them is perfect in one way or another. Both of these batteries have their pros and cons. One way to select which one is better is that you know and evaluate the batteries according to your needs.

Here we will enlighten some points that will help you in deciding which battery is better for you.

What are you Going to Use the Battery For?

This is the most important thing that you need to consider when selecting a battery. If you are using the battery in a product that requires an adequate power delivery but does not care for the delivery time, then you might prefer the lithium polymer battery. This is because these batteries have a low storage capacity, but they can provide adequate power.

If it is needed to provide the power for a longer time, then you may need the lithium-ion batteries because they can hold more charge.

Are you Concerned About the Size of the Battery?

If the size of the batter is one of your major concerns, then you can select lithium polymer batteries because they are also available in low profile enclosures.

Is Cost a Concern for You?

When cost is a major concern, then it is good to select the lithium-ion battery because it is easily available at comparatively cheaper rates.

If you are replacing the battery from an old product, do you know which battery it used before?

If you are replacing a battery, then you should use the same battery that was used before.

Can You Take Lithium Polymer Batteries on a Plane?

Taking the batteries with you on a flight is another problem of major concern throughout the world. This is because of some of the past incidents where the batteries were the cause of an explosion or a fire on the place. The batteries are allowed to be taken with you on a plane only under special circumstances. Some of those circumstances are discussed here.

The Batteries in the Electronics.

If you are carrying any type of electronic item that has a battery. Then you must keep this device with you in your hand-carry storage. Another thing to notice is that the battery must not be more than 100-watt hour. Otherwise, that device will not be allowed to be taken on a flight.

Separate Batteries.

In case you are keeping spare batteries with you, then you have to follow some rules as well. The batteries cannot be any bigger than 160-watt hours. You also have to add these batteries with you on the flight.

Can the Batteries Be Checked in with Your Luggage?

No authorities allow you to keep the batteries in your luggage because there is a chance of having an explosion or a fire due to the batteries.

Rules for carrying the batteries in the plane.

1. In any case, the battery will be in your hand carry.
2. The spare batteries must be protected at their terminals so that they can not cause any sparks.
3. You must use separate plastic containers, an efficient amount of electrical tape, or a professional battery barring case to carry batteries with you on a plane

Conclusion

We hope that this was more than enough to make any of your confusion clear regarding the two most popular types of rechargeable batteries. By reviewing the differences and specifications of the batteries, you can make your buying decision efficiently.

This awesome 3-in-1 drone has an on-board camera that snaps photos and records video while in-flight up to 150 feet away! It also is easy to fly – kids just toss to launch it – and features a crash-resistant design with motion-sensitive auto stabilizers for greater control. When converted to car mode, it can even crawl up walls!

V-shaped Bicopter

Despite the vast majority of drones using four rotors, the new V-Coptr Falcon from Zero Zero Robotics utilises only two. Most consumer drones offer a flight-time of 30 minutes or less, but the V-Coptr can fly for up to 50 minutes. The technology also reduces propeller noise, and the drone’s 12-megapixel camera promises high-quality still pictures and 4K video at 30 fps.

Rocket Drone

The Radical Rocket is a ducted-fan UAV designed and built in four weeks by Ex-RAF Electronics Engineer Lee Molyneux during the Covid-19 pandemic. It uses a 3S, 5000mAh, 120C battery.
