1、 What is a soft pack lithium battery

(1) When it comes to soft pack batteries, many application scenarios should come to mind. They are not unfamiliar in our daily lives. Apart from power lithium batteries, power batteries are the most common battery components in 3C electronic devices. For example, the internal components of a mobile phone are integrated and cannot be disassembled without authorization.

(2) Soft pack rechargeable battery: The difference between soft pack batteries refers to the use of aluminum plastic composite film (commonly known as aluminum plastic film), which depends on the different packaging materials of lithium motor shells. Other lithium batteries are similar to positive, negative, lithium battery electrolytes, diaphragms, and other lithium battery materials.

2、 Lithium battery packaging method

(1) The overall packaging of the lithium battery casing can be divided into: first generation, steel casing; Second generation, aluminum shell; The third generation, soft wrapped aluminum plastic film.

(2) The significant harm of rechargeable lithium batteries is due to the instability of lithium battery materials and other unexpected comprehensive factors, which can cause uncontrolled heating and invisible vapor deposition inside the rechargeable battery. The steel or aluminum casing creates a fixed space, limiting the expansion of the vapor and causing an explosion of the rechargeable battery. That way, the soft packaging of the battery emerged, which was born in response to the times.. Soft packaging batteries often have aluminum plastic film that is too soft and has physical denaturation. Once there is a safety risk, the most common one is a burst of gas.

3、 Advantages of Soft Pack Lithium Batteries

Relatively safe except for soft pack lithium batteries. Compared to steel casing, lithium batteries can also save net weight, volume, and reduce internal resistance. In that way, improving the relative density, quality, or bulk density of lithium batteries would be of great benefit. In addition, the soft pack battery also has the characteristics of low cycling system consumption and diverse design schemes and packaging styles.
