Cylindrical, square and flexible pack lithium battery structure characteristics
At present, the mainstream lithium battery packaging form there are three important, namely, cylindrical, square and soft pack, different packaging structure means different characteristics.
2.Square lithium batteries usually refers to aluminum or steel shell square battery, the overall accessory weight is lighter, the relative energy density is higher. With the rise of automotive power lithium batteries in recent years, automotive range and battery capacity of the contradiction between the increasingly prominent, the domestic power lithium battery manufacturers more than the use of higher energy density of the battery aluminum casing square battery-based
3.Flexible packaging materials are usually divided into three layers, i.e., the outer barrier layer, the permeability barrier layer , and the inner layer . The packaging material and structure of lithium flexible pack battery gives it a series of advantages, good safety performance, light weight, good cycling performance.
