BATTERY, BATTERY PACK AND ELECTRICAL DEVICE

WIPO Patent Application WO/2024/055978

A1

A battery, a battery pack (200) and an electrical device. The battery comprises a housing (120), an electrode assembly (110), and a pole (130), wherein a first outer wall of the housing (120) is recessed inwards to form a first recess (121), the first recess (121) being provided with a first side wall (1211); the electrode assembly (110) is accommodated inside the housing (120); and the pole (130) is arranged on the first side wall (1211) of the first recess (121) and is electrically connected to the electrode assembly (110), the diameter of the pole (130) being d, the height of the first side wall (1211) being b, 1/4≤d/b≤1, and the height of the first side wall (1211) being the size of the first outer wall in the direction in which the first recess (121) is recessed. The proportional relationship between the diameter d of the pole (130) and the height b of the first side wall (1211) is set, such that a sufficient assembly space can be provided for the pole (130), and excessive loss of energy density of the battery due to the arrangement of the first recess (121) on the housing (120) can further be avoided.
