  The usual lithium ion battery shells are: plastic, steel shell and aluminum shell. The shell design of the lithium -ion battery mainly includes: PVC heat seal, plastic, metal. At present, the best sales on the market are aluminum alloy shells, and aluminum alloy is one of them. Aluminum alloy has a lower density, but its strength is high, close or higher than high -quality steel, and has good plasticity. There are three main types of lithium -ion batteries: steel shells, aluminum shells, and soft shells.

  1. Steel shell

  Early square lithium -ion batteries were mostly steel shells, which were mainly used in mobile phones. However, due to their lighter quality and poor safety, they were gradually replaced by aluminum and soft packaging.

  However, in the lithium -ion battery industry, it is another situation. Most manufacturers use steel to make batteries, because the physical properties and pressure resistance of steel are stronger than aluminum shells. After the improvement of multiple companies, safely, safe and safe The measures were installed inside the battery. The cylindrical battery of the steel shell has been greatly improved. Most of the current laptops are used as a power shell.
