Title:
CELL ISOLATION SLEEVE AND BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2021/196200
Kind Code:
A1
Abstract:
A cell isolation sleeve and a battery module, relating to the technical field of power batteries. A first vertical strip hole (11) and a second vertical strip hole (21) are respectively provided on a left connecting side (1) and a right connecting side (2) of the cell isolation sleeve, water drops on the side surface of a cell spread to the left connecting side (1) and the right connecting side (2), the water drops will gather in the first vertical strip hole (11) and the second vertical strip hole (21), thereby blocking the continued spread of the water drops, and due to gravity, the water drops will fall when gathering to a certain size, thereby solving the problem of dangerous phenomena such as electric leakage, short circuit, fire, and explosion caused by the water drops on the side surface of the cell flowing into a battery module through the cell isolation sleeve.
