Introduction of polymer lithium battery

　　During charging and discharging, lithium ions are charged into the positive and negative electrodes; The lithium battery material is usually contained in the lithium positive electrode or through the electrolyte negative electrode material, and is a representative of the high-energy batteries that have emerged in recent years.

　　Polymer lithium batteries are special because they have different electrolytes than other conventional lithium batteries. Conventional lithium batteries use liquid electrolytes and polymer lithium batteries use new solid electrolytes. But the positive material used is the same as the negative material. The liquid electrolyte of the lithium battery can be replaced by a solid electrolyte, so that is the polymer lithium battery, they can be made into any shape.

　　A traditional lightweight shell is used on the battery box, and the energy of the entire battery is manipulated by a density steel or aluminum shell battery, and an aluminum-plastic composite film. Therefore, the polymer lithium battery is composed of a high polymer solid electrolyte, the cost is far more than the liquid electrolyte lithium battery, and is currently one of the batteries used in smart devices, mobile phones, tablet computers, as well as aircraft models, car models, drones and other wearable devices.

　　Polymer lithium batteries need to pay attention to short circuit, polymer lithium batteries are prone to short circuit during charging.

　　Including: internal short circuit, external short circuit, etc. But most lithium-ion batteries now have anti-short circuit protection and wiring, in many cases, this protection circuit may not necessarily work in a variety of circumstances, and can only play a limited role in the wire to prevent short circuits.
