What is a soft pack lithium battery

Speaking of soft-pack batteries, first of all, what is a soft-pack lithium battery? In fact, soft-pack lithium batteries are not unfamiliar in our daily lives. In addition to power lithium batteries, power lithium ion batteries are the most common battery components in 3C electronic equipment. For example, the inside of a mobile phone is an integrated rechargeable battery that cannot be disassembled without authorization. Soft-pack rechargeable battery: The difference of the soft-pack battery refers to the difference in the packaging materials of the lithium motor shell. Aluminum-plastic composite film (commonly known as aluminum-plastic film) is used. Other lithium batteries are similar to lithium battery materials such as positive, negative, lithium battery electrolyte, and diaphragm. The overall packaging of the lithium battery case can be divided into: the first generation, steel case; the second generation, aluminum case; the third generation, soft package aluminum plastic film. Steel shell batteries, aluminum shell batteries: Lithium battery rechargeable batteries cause greater damage, which is the likely instability of lithium battery materials and other unexpected comprehensive factors that cause thermal runaway and cause invisible vapor deposition in the rechargeable battery. The steel or aluminum shell has a fixed space, which limits the swelling of the vapor and causes the rechargeable battery to explode. In that way, the soft package packaging of the battery appeared, which was born in time. . Soft-packed batteries, commonly used aluminum-plastic film is too soft and deformable. Once there is a safety risk, the air bulge will crack at most. Advantages of soft-packed lithium batteries: In addition to soft-packed lithium batteries, they are relatively safe. Compared with the steel casing, the lithium battery can also save the net weight, volume, and reduce the internal resistance. In that way, improving the relative density quality or bulk density of lithium batteries is of great benefit. In addition, the soft pack battery also has the characteristics of low circulatory system consumption and various design methods and packaging. It is based on this advantage of the lithium battery soft pack. Greatly attracted the attention of countries all over the world, industrialization.
