WIPO Patent Application WO/2024/074083
Kind Code:
A1
Abstract:
A battery, comprising a first half housing, a second half housing and an arc-shaped battery cell, wherein the first half housing is connected to the second half housing to enclose an arc-shaped accommodating cavity, which matches the arc-shaped battery cell, and the arc-shaped battery cell is accommodated in the arc-shaped accommodating cavity. By means of the arrangement of the arc-shaped accommodating cavity, the structure of an aluminum-plastic film housing fits with the structure of the arc-shaped battery cell, such that the operations of encapsulating the arc-shaped battery cell in the aluminum-plastic film housing are facilitated, and the effect of fixing the arc-shaped battery cell in the aluminum-plastic film housing is improved, thereby reducing the probability of relative movement of the arc-shaped battery cell and the aluminum-plastic film housing, and thus achieving the technical effect of improving the safety of an arc-shaped battery. Moreover, by means of the arrangement, the space in the aluminum-plastic film housing can be fully used by the arc-shaped battery cell, such that the arc-shaped battery can maintain a relatively high energy density.
