The full name of the polymer battery you are referring to is lithium polymer battery. It is a type of lithium battery. In terms of battery cells, lithium batteries are divided into first-generation steel-cased lithium batteries, second-generation aluminum-cased lithium batteries, and third-generation lithium polymer batteries.
Since the polymer battery is encapsulated in an aluminum composite film, the film is only 0.3m thick and there is the largest space for internal reaction materials . Aluminum composite film is much lighter than steel shell. the aluminum hull. The aluminum composite film can pull it up effectively slow down the air pressure generated when the battery reacts badly and avoid the possibility of explosion.
The lithium polymer battery is the battery with the highest capacity, the lowest weightlight and the best safety among lithium batteries.
1. Lithium batteries are divided according to appearance: there are square lithium batteries (such as commonly used mobile phone battery cells) and cylindrical batteries (such as 18650); Lithium battery outsourcing Materials are divided into: lithium batteries in aluminum casing, lithium batteries in steel casing, soft batteries
3. Lithium batteries are divided into positive and negative electrode materials (additives): lithium purate (LiCoO2) battery or lithium manganate (LiMn2O4), lithium iron phosphate battery, disposable lithium manganese dioxide battery; other point: lithium ion LIB, polymer PLB
Different performance and usage points:
Disposable -- lithium manganese battery -- 3 volt button cell
High capacity (high platform) -- used in digital productsmobile phone devices
High rate;-- -Used in electric vehicles, power tools and aircraft models
High temperature;---Miner's lamp, interior lighting , built-in emergency power supply of the machine;
Low temperature;---Outdoor environment, North Antarctica (winter);
