## Abstract

The present application discloses a battery cell holder, a battery module, a battery, and an electrical apparatus. The battery cell holder includes: a holder body and an insulating member. The holder body is provided with at least one first channel in a first direction, and the insulating member is arranged on an outer surface of the holder body. The insulating member covers part or all of the outer surface, and the surface of the insulating member facing away from the holder body is capable of fixing a battery cell. By providing the holder body with the first channel, and fixing the battery cell to the holder body on the peripheral side of the first channel, after the battery cell radiates heat, the heat flows out through the first channel, so that the temperatures of the battery cell itself and the environment surrounding the battery cell can be reduced, thereby alleviating the battery safety problem caused by the accumulation of heat during the use of the battery.
