Abstract

A battery shell assembly includes a post terminal and a first shell, the first shell comprises a first shell part and a second shell part connected with the first shell part, the first shell part is arranged in a protruding mode relative to the second shell part and defines a containing space, and the post terminal is fixed to the first shell part and partially contained in the containing space. The invention also provides a battery with the battery shell assembly.

Description

technical field [0001] The present application relates to the field of batteries, in particular to a battery casing assembly and a battery with the battery casing assembly. Background technique [0002] Batteries are popular due to their portability, and are widely used in portable electronic devices and other fields. As we all know, a battery usually includes a casing, a top cover, and a battery cell. Wherein, the electric core is located inside the housing, and the top cover is located at the opening at the upper end of the housing. A pole is pierced through the top cover, and the pole is electrically connected with the electric core to realize external power supply. However, the pole will occupy a certain space in the casing, resulting in a loss of energy density. Secondly, the pole piece is easy to pierce the pole piece in the battery cell during the crush test (crush test), resulting in a short circuit and fire, resulting in a potential safety hazard.
