Lithium polymer vs lithium ion battery which is better

A lithium polymer battery is rectangular in shape and is very thin. These batteries are used in a variety of devices from laptop computers, cell phones, and other electronic devices. Other names for lithium polymer batteries are “LiPo” and “LiPoly.” If a person had to choose which is safer, a lithium polymer or a lithium ion battery, most would say the polymer based battery is safer. The commone Lipo batteries, we can see that is RC lipo battery. Any battery can explode if over charged but the polymer battery is not as likely to burst into flames like the ion based battery. The lithium polymer battery is what many call a pouch cell design battery. This is what makes it lighter than the lithium ion battery. The lithium polymer battery is designed where the electrode sheet and its separator are laminated onto each other. This eliminates the metal needed in the ion batteries. Another benefit of the lithium polymer battery is that manufactures can shape the cell into any form that is needed for any type of device.


Application of lithium polymer battery

LiPo cells provide manufacturers with compelling advantages. They can easily produce batteries of almost any desired shape. For example, the space and weight requirements of mobile phones and notebook computers can be completely satisfied. Also, they have low-self discharge rate, which is about 1%.

Radio controlled equipment and Airsoft

LiPo batteries have just about taken over in the world of radio-controlled aircraft, radio-controlled cars and large scale model trains, where the advantages of lower weight and increased capacity and power delivery justify the price.

As of the beginning of 2013, LiPo packs of 1.3 Ah exist, providing 45C continuous discharge, and short-time 90C bursts. Bigger packs of 4.5 Ah may feature discharge rates of 70C, with 140C bursts.

Much More have introduced a completely new line of Impact Lipo battery called FD or Flat Discharge. The new configuration gives a flatter discharge curve meaning you get more voltage for longer instead of a steady drop in voltage as in regular packs. Available in 7200mAh 80C & 6000mAh 80C stick packs, 6000mAh 80C & 5000mah 3s lipo (low height) saddle packs, 4600mAh 80C shorty pack, 6400mAh 70C 1S & 3000mAh 60C 2S 1/12th packs and a 4200mAh 50C (low height) stick pack.

Lithium ion batteries use carbon anode and lithium cobalt oxide cathode and an electrolyte gel. Chemistry of lithium polymer is much similar to Li-ions but it also uses a porous separator which converts into gel on exposure to electrolyte. Also Li-polymers employ different architecture. These batteries do not use metal shell like Li-ion batteries. Li-polymer battery is in next level of development and replaces liquid electrolyte with a plastic or polymer electrolyte thus allows these batteries to be molded in various shapes and sizes. The chemical construction of Li-ion battery restricts it to only rectangular shape.

Selecting the right battery for a specific task can become quite a technical challenge which is why retail battery packaging sometimes lists the kind of device they are best suited for. An example of the problems with selecting the best battery technology for a specific task might be the new Boeing Dreamliner. The entire fleet was grounded for several weeks because of a battery catching fire.
