Title:
BATTERY CELL, BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/077630
Kind Code:
A1
Abstract:
The embodiments of the present application belong to the technical field of batteries. Provided are a battery cell, a battery and an electric device. The battery cell comprises a housing, an electrode terminal, an electrode assembly, a current-collecting member and an insulating member, wherein the housing has a wall portion; the electrode terminal is arranged on the wall portion; the electrode assembly is arranged in the housing and has a first tab; the current-collecting member connects the first tab with the electrode terminal; the insulating member is arranged between the current-collecting member and the wall portion and is used for insulating and isolating the current-collecting member from the wall portion; and in the thickness direction of the wall portion, the insulating member has a first surface which faces and is closest to the current-collecting member, and a projection of an outer edge of the current-collecting member is located in the first surface. The first surface can play a limiting role on the current-collecting member, thereby reducing the deformation of the current-collecting member in a direction approaching the wall portion, reducing the risk of staggering of positive and negative electrode sheets of the electrode assembly due to excessive deformation of the current-collecting member, and effectively improving the safety of the battery cell.
