Abstract: A battery cell, a battery, and an electric apparatus are provided. The battery cell includes a housing, an electrode lead-out member, an electrode assembly, and an adapter member. The housing is provided with an accommodating cavity. The electrode lead-out member is disposed at the housing. The electrode assembly is accommodated in the accommodating cavity, where the electrode assembly includes a main body portion and a tab led out of the main body portion. The adapter member is configured to connect the tab and the electrode lead-out member, and a light absorbing layer is applied to a welding position of the adapter member. The light absorbing layer is applied to the surface of the adapter member to reduce reflection, increasing the energy absorption rate of the adapter member, and lowering the welding power, and reducing the possibility of other components of the battery cell being burned, thus improving the safety of the battery cell.

Abstract: An end cap assembly includes an end cap configured to close a housing of a battery cell, an adapting member configured to electrically connect an electrode assembly of the battery cell to an electrode terminal of the battery cell, and a supporting member between the adapting member and the end cap. An explosion-proof mechanism provided at the end cap is configured to be actuated to release an internal pressure of the battery cell when thermal runaway occurs in the battery cell. The supporting member is made of a high-temperature-resistant material. An orthographic projection of the adapting member on a first surface of the end cap at least partially overlaps an orthographic projection of the explosion-proof mechanism on the first surface of the end cap and an orthographic projection of the supporting member on the first surface. The first surface is a surface of the end cap facing the housing.
