Liquid lithium-ion battery (Li-ion) is widely used in communication and electronics industry as an efficient energy carrier, especially in personal communication tools such as mobile phones and PDAs. However, in the past two years, with the rapid development of communication technology, mobile phone color screen technology, MMS technology, Bluetooth technology and camera technology continue to appear, the battery capacity, volume, weight and electrochemical performance and other indicators put forward higher requirements, the traditional liquid lithium battery has become more and more unable to meet the new needs. The emergence of new polymer lithium-ion batteries (Li-Poly) caters to this demand. Polymer lithium battery is the third generation of lithium-ion battery developed on the basis of the original steel shell and aluminum shell battery, with its lighter, thinner, higher energy density characteristics, favored by domestic and foreign communication terminal manufacturers and design companies. The most fundamental difference between polymer lithium-ion batteries and liquid lithium-ion batteries is that the electrolytes used in the two are different. The electrolyte of polymer lithium battery is solid from the appearance, which is called polymer solid electrolyte. This electrolyte is a kind of polymer material that is in a solid state, but can dissolve and support the electrolyte like a liquid, and can have ion migration phenomenon.

　　The following is a list of the use of polymer lithium battery eight advantages for peer reference.

　　A.K.E 12V / 1300mAh polymer lithium battery project template, equipped with automatic protection board, can effectively protect against short circuit, overcharge, overdischarge. Moreover, the battery can be reliably charged using an ordinary charger, without having to worry about overcharging or undercharging. Polymer lithium battery unit voltage is usually 3.7V, the highest voltage is 4.2V.
