Description

[0002] Solid-state batteries are a very common energy storage device and are widely used in various fields. Solid-state batteries are generally used in the form of battery packs fixed in battery shells. The energy storage solid-state battery pack will generate more heat during use. In order to ensure that the entire energy storage solid-state battery pack can dissipate heat well, cooling pipes are generally provided on the battery shells.
