Compared with previous battery, high energy, miniaturization and light weight are kinds of chemical properties of the battery In shape, lithium polymer battery has ultra-thin characteristics, which can match the need of some products, and made into different shapes and capacity of the battery.

Silicon is found so far lithium ion batteries cathode materials that has highest specific storage (4200 mAh/g) It is one of the most promising anode materials, but as silicon lithium battery, there are some negative application bottlenecks.

Lithium ion batteries because of the high life, high capacity is widely used, but with longer duration of use, the existence of ballooning, safety performance is not ideal and loop attenuation speed problem is increasingly serious, caused the depth analysis and inhibiting the lithium electricity industry According to experimental research and development experience, the author will lithium battery ballooning reasons fall into two categories, one is the thickness of the battery pole piece ballooning change; The second is due to electrolysis melt oxidation decomposition gas ballooning.
