According to the electrolyte elements which are used in Lithium Ion Batteries,Lithium Ion batteries are divided into Liquified lithium-Ion battery (abbreviation:LIB) and Polymer Lithium-Ion Batter (abbreviation:PLB) ,It utilized in the PLB cathode products and LIB would be the same, the anode components are divided into cobalt acid lithium, manganese acid lithium, ternary materials and lithium iron phosphate material, adverse really graphite, functioning principle of the battery is almost precisely the same.Their most important difference is the different electrolytes, LIB applying liquid electrolyte, PLB with sound polymer electrolyte as a substitute for, at current the majority of the polymer gel electrolyte.
1.classification
reliable
Reliable polymer electrolyte of lithium ion battery electrolyte to the polymer that has a mixture of salt, the battery the ionic conductivity at space temperature is low, can be utilized at space temperature.
gel
Gel polymer electrolyte for lithium ion batteries is in sound polymer electrolyte adding plasticizer and also other additives, therefore enhance the ionic conductivity, the battery can be used at space temperature.
polymer
Polymer lithium ion battery getting a thin form, and of any spot of any form, etc., so you can use plastic composite film manufacturing the battery case, which could enhance the ratio with the entire battery capacity; polymer lithium ion battery may also be higher molecule as cathode material, its good quality will be enhanced by over 20 % extra power than the latest liquid lithium-ion battery.
2.Do not charge overcharge
Polymer lithium-ion battery, should the charging time is also extended, will increase the possibility of expansion.
3. Pros and disadvantages Advantage
A. single battery voltage up to 3.6v ~ 3.8v 1.2V voltage is considerably greater compared to the nickel-metal hydride and nickel cadmium batteries.
B. capability density, and its capability is 1.5 to 2.5 occasions the density of nickel-metal hydride batteries or nickel-cadmium batteries, or higher.
C. Self-discharge, spot a long time following the reduction of its capacity is smaller.
D. Long lifestyle, the standard utilization of the cycle life can reach more than 500 instances.
E. no memory impact, prior to charging isn't essential to vent the remaining capacity, easy to use.
F. Very good security effectiveness
Polymer lithium aluminum flexible packaging construction adopted in the occasion of safety complications arise, polymer batteries will not explode, it is going to only drums.
4. modest thickness, can do thinner
Slim, the 7.4v 5000mah lipo battery might be assembled into the credit card. Ordinary liquid lithium employing the 1st custom shell, soon after the Cypriot village of positive and negative materials system, the thickness of 3.6mm or less technical bottlenecks do exist, as well as the thickness from the polymer batteries can be carried out 1mm or less.
5. Light weight
Applying a polymer electrolyte battery without metal shell as protection packaging. Polymer battery fat compared with all the very same capacities of steel lithium, 40% lighter, 20% lighter than aluminum battery.
6. The internal resistance
Polymer batteries inner resistance than ordinary liquid modest core, the current domestic polymer batteries internal resistance of 35m can do even much less, greatly reducing the battery from your power to lengthen the standby time, is usually attained together with the worldwide degree. This assistance significant discharge latest lithium polymer is great for remote control model because the most promising alternative to nickel-hydrogen battery solutions.
7. The shape is often personalized
Makers need not be restricted to normal kind, it could be economically produced of ideal size. Polymer battery can be extra in accordance to client demand or minimize the thickness from the 2 cell lipo batteries, the advancement of new designs of batteries, low cost, mold cycle is quick, and a few can even be tailored based on the form of the cell phone to get advantage in the battery housing space, strengthen battery capability.
8. Outstanding discharge traits
Polymer battery with gel electrolyte, compared to liquid electrolyte, gel electrolyte getting a steady discharge characteristics and greater discharge platform.
9. Plate Design and style Simple
Because of this of polymer supplies, batteries no fire, no explosion, batteries itself has adequate security, hence safeguarding the circuit design and style polymer battery could be viewed as omitted PTC and fuse, thereby conserving the cost of the battery.
