Lithium-ion polymer rechargeable battery packs are used in
1. The toy and electric vehicle industry, such as electric remote control cars, electric intelligent robots. Many toys that require high power are used in lithium-ion polymer rechargeable battery packs.
2. Electronics industry, such as wireless Bluetooth headphones, wireless audio, handheld automatic vacuum cleaner.
3. Solar lighting industry, for example, solar street lights, solar garden lights, solar lawn lights, etc.
Advantages of polymer lithium-ion rechargeable battery pack.
1. Good safety performance
Polymer lithium battery in the structure of the choice of aluminum plastic soft packaging, different from the plastic shell of the liquid battery cells, if the occurrence of safety hazards, the liquid battery cells are prone to explosion, while the polymer battery cells will at most only gas drum.
2. Thin and small, can be made thinner
Ultra-thin, the battery can be installed into the credit card. Ordinary liquid lithium battery choose to customize the shell first, then plug the positive and negative village material method, thin thickness to do below 3.6mm there is a technical bottleneck period, polymer cells will not have this problem, the thin thickness can be done below 1mm, to meet the direction of the current demand for mobile phones.
3. Customisable shapes
Manufacturers do not need to stick to standard shapes and can economically make them into the right size. Polymer batteries can be increased or reduced in thickness to develop new cell models according to customer needs, at a low price, and with a short molding cycle.
4. Simple design of protection plates
Given the choice of polymer materials, the cells do not catch fire or explode, and the cells themselves have sufficient safety performance, so the protection circuit design of polymer batteries can consider ignoring PTC and fuses, thus saving battery costs.
