Use the same winding process as the production of liquid lithium ion battery, wind up the positive electrode, negative electrode and electrolyte film, and package it with aluminum foil.
Cut the anode and cathode into a certain size, make them with electrolyte film by hot-pressing technology, and then package with aluminum foil.
Due to the polymer materials,
the cell will not catch fire or explode.

capacity specification, and 20%
lighter than the aluminum case battery.
the capacity is 10~15% higher than
that of the steel case battery with
the same size, and 5~10% higher
than that of the aluminum case battery.
The resistance of the polymer battery
is less than that of liquid battery.
The resistance can be less than 35 mΩ.

The capacity of a lithium polymer battery depends on the thickness, width and length. It also depends on the material and size.
Fast estimation of polymer battery capacity, commonly used estimation formula (estimation only)：
Capacity = Thickness * Width * Length *K (The unit of K is mah/mm^3)
Internal impedance refers to the impedance encountered by the current flowing through the lithium ion battery when the lithium ion battery is working. It is mainly composed of electrode materials, electrolyte, separator impedance and the contact impedance of each part, which are affected by the size, structure and assembly of the battery.
Charge Rate = Charge Current/Rated Capacity
The maximum charging rate is the safest, but it is not the best charging rate. A lower charging rate can better extend the service life of the battery.
Discharge Rate=Discharge Current/Rated Capacity
Discharge rate maintains safe discharge speed of the battery. In the specified time, the battery releases its rated capacity current, which is equal to the battery rated capacity multiple. Discharge rate is expressed by letter C.

The lithium polymer battery has a certain life. It doesn't mean that you can prolong battery life without using. Battery maintenance only has corresponding standards during using.
The process of assembling lithium polymer battery cells is called PACK, which connects single battery or multiple cells into lithium ion battery modules in series and parallel.
Lithium polymer battery pack consists of battery pack, bus bar, flexible connection, PCM, exterior package, output (including connector), highland barley paper, plastic holder and other auxiliary materials.
3.6V 3200mAh Explosion-proof Lipo Battery Special Handheld Equipment Cell model: LA505357FB/1600mAh/3.6V Nominal voltage: 3.6V Nominal capacity: 3200mAh Application:oil station, gas station, mining, etc.
Connector is commonly known as plug-in unit, plug and sockets, etc. It is used to connect power supply and signal device. There are wire to wire connector and wire to board connector.
Lithium polymer batteries are considered to be a relatively environmentally friendly way of storing energy. However, if the discarded lithium polymer batteries are not recycled properly, they may cause environmental pollution.
|Category||Conventional Materials||Potential Environmental Pollution|
|Anode Material||LiCoO2/LiMn2O4/LiNiO2||Heavy metal pollution; Co, Ni,
Mn are strong carcinogens, toxic substances,
and may change the environmental pH.
|Electrolyte||LiPF6LiBF4/LiAsF6||Change the environmental pH; Fluorine pollution|
|Electrolyte Solvent||EC/PC/DC||It is difficult to degrade; Toxic;
Burning will produce greenhouse gases.
|Separator||PP/PE||Difficult to degrade|
|Adhesive||PVD/VDF/EPD||Fluorine pollution; Difficult to degrade|
When choosing lithium polymer batteries, we should search for well-known brands, so that the quality of batteries can be guaranteed. Although the price of many small brands in the market is cheap, the battery may have short life and poor quality.
Check if the capacity is clearly marked. A battery pack without a clearly marked capacity (such as 1000mAh or 1000 MAH) may be a poor quality battery pack or a recovered battery pack without quality assurance.
Without a PCM, the lithium polymer battery has the risk of deformation and leakage. In the competitive market, companies have sought cheaper PCM, or omitted them, leaving lithium polymer batteries explosive risk on the market.
