When it comes to Nickel Hydride No. 5 battery, first of all, what is a Nickel Hydride No. 5 battery?

　　In fact, soft-pack lithium batteries are no stranger to our daily lives. In addition to power lithium batteries, power batteries are the most common battery components in 3C electronic equipment. For example, the battery inside a mobile phone is integrated and cannot be disassembled or assembled without authorization.

　　Soft pack rechargeable battery:

　　The difference between the soft-pack batteries referred to is mainly due to the different packaging materials of the lithium motor casing, which is the use of aluminum-plastic composite film (commonly known as aluminum-plastic film). Other lithium batteries are similar to lithium battery materials such as positive stage, negative stage, lithium battery electrolyte, and diaphragm.

　　The overall packaging of lithium battery casing can be divided into: first generation, steel shell; second generation, aluminum shell; third generation, soft aluminum plastic film.

　　Steel case battery, aluminum case battery:

　　The biggest danger to lithium-ion batteries is that the possible instability of the lithium-ion battery material and other unexpected comprehensive factors can cause thermal runaway and cause invisible gas deposition in the battery. The steel or aluminum casing creates a fixed space that limits the expansion of gas, causing the battery to explode.

　　In this way, the soft package packaging of batteries appeared, which came into being at the right time. . For batteries packaged in soft packages, the aluminum-plastic film commonly used is too soft and has deformation. Once a safety risk occurs, the most likely outcome is that the air drum will burst.

　　Advantages of soft pack lithium batteries:

　　Except for soft-pack lithium batteries, they are relatively safe. Compared with steel shells, lithium batteries can also save weight, volume, and reduce internal resistance. In this way, improving the density quality or volume density of lithium batteries will be of great benefit. In addition, soft-pack batteries also have the characteristics of low circulation loss and various design and packaging styles.

　　It is based on this advantage of lithium battery soft pack. It has greatly attracted the attention and industrialization of countries around the world.
