Classification and characteristics of polymer lithium batteries

by:Vglory      2021-05-14
The important structure of the battery is composed of three parts: positive electrode, negative electrode and electrolyte. According to the current meaning, the so-called polymer lithium battery is a battery system in which at least one or more than three polymer materials are used as its important substrate. The polymer lithium battery is assembled in a soft package material (aluminum foil). At present, the polymer lithium batteries processed in batches in the world are divided into two categories according to the structure: (1) Winding type, which adopts the same winding process as liquid lithium batteries. The positive electrode, negative electrode and electrolyte membrane are wrapped with aluminum foil. (2) Cut the positive and negative electrodes of a certain size into thin slices, press them together with the electrolyte membrane by a hot pressing process, and then wrap them with aluminum foil. Lithium polymer batteries can be divided into three types according to the electrolyte: (1) Gel polymer electrolyte lithium battery, adding additives to the solid polymer electrolyte to improve ion conductivity, so that the battery can be used at room temperature; (2) solid polymer electrolyte Material electrolyte lithium battery, the electrolyte is a mixture of polymer and salt, its ionic conductivity is low at room temperature, suitable for high temperature use; (3) Composite gel polymer anode material lithium battery, as a conductive polymer anode material, its ratio It can be three times of the existing lithium battery and is the latest generation of lithium battery. The characteristics of the polymer lithium battery: It can be thin in appearance (the thinnest 5mm), any area, and any shape, which greatly improves the flexibility of battery shape design; no additional electrolyte is required during the battery process, which is more stable and environmentally friendly: no leakage , No heavy metals, no pollution; High energy density: 170~200Wh/Kg; Large-capacity single-cell battery can prevent the influence of parallel connection. The above is ge's classification of polymer lithium battery characteristics and appearance. Please continue to browse the wonderful page of ge website.
