What shells are generally used in lithium batteries.home solar energy storage lithium battery Factory

　　What should I pay attention to when designing the classification of lithium battery shells? Lithium battery shell is a protective shell that protects the cells and internal circuits, and the shell of the lithium battery is the key component of the entire battery. In order to ensure the special performance of the battery's waterproof and shockproof, the design of the lithium battery is also a key link of the battery, so pay attention to the correct method during the design process. The following are some points of the classification of lithium battery shells and the design of the shell.

　　1. Steel shell -shaped lithium ion battery,

　　Early corner lithium batteries were mostly steel shells, which were mainly used on mobile phone batteries. However, due to their lighter quality and poor safety, they were gradually replaced by aluminum and soft packaging. There are still many small factories in production B -class mobile phone batteries, MP3, MP4 and other low -end products.

　　However, cylindrical lithium batteries are another case. Most of the manufacturers use steel as batteries, because the physical properties and pressure resistance of steel are stronger than aluminum shells.

　　Second, lithium ion aluminum shell

　　Aluminum -shell lithium batteries are slightly better than steel shells because of their weight and safety, and they occupy an important position in the current mobile phone battery market. Because the mold opening cost of aluminum alloy shells is very high, there are not many models, and the number of orders is large, mainly for some commonly used mobile phone batteries.

　　Third, lithium ion soft packaging

　　Soft -packaged lithium ion batteries have gradually expanded their market share due to their light weight, low -mode cost, and safe and reliable. At present, mobile phones, laptop computers, electric tools and other fields have a certain development space. It can be expected that the market share of soft packaging lithium ion batteries will become larger and larger, because its products are aluminum -plastic film, so its pressure resistance ability is very low, which is limited by domestic craftsmanship and environment. Therefore, this situation occurs. The probability is relatively high.
