CELL ISOLATION SLEEVE AND BATTERY MODULE

The invention relates to the field of power battery technologies, and more particularly, to a cell isolation sleeve and a battery module. A left connecting edge and a right connecting edge of the cell isolation sleeve are respectively provided with a first vertical hole and a second vertical hole, water drops which spread to the left connecting edge and the right connecting edge from a side surface of a cell will aggregate in the first vertical hole and the second vertical hole, thus preventing the water drops from spreading continuously. Moreover, due to an action of gravity, the water drops will fall off after aggregating to a certain size, thus solving a problem that the water drops on the side surface of the cell are likely to flow into the battery module through the cell isolation sleeve, resulting in dangerous phenomena such as electric leakage, short circuit, fire and explosion, and the like of the battery module.
