Abstract
A battery cell, a battery, and an electric apparatus are provided. The battery cell includes a housing and a first conductive layer. The housing includes a first wall portion, where the first wall portion has a first surface, the first wall portion is provided with a recess, and the recess has a side surface connected to the first surface. The first conductive layer is accommodated in the recess, and the first conductive layer is in contact with the side surface. The provision of the first conductive layer improves the electric field distribution in a region, provided with the recess, of the first wall portion, resulting in a more uniform electric field strength distribution, reducing the risk of tip discharge at a connection position between the side surface and the first surface in a high-voltage environment, and improving the reliability of the battery cell.
