AI Technical Summary

Technical Problem

In existing battery cells, the existence of the Ba plate limits the increase in the energy density of the battery cell, because the Ba plate needs to occupy a certain space to avoid interference, resulting in an increase in the height of the pole column and limiting the space utilization of the battery cell.

Method used

A battery cell is designed, which has the first side and second side wall of the first side of the two sides that are distributed on both sides of the thickness direction. The first side wall forms the part of the air department to accommodate the chip, thereby reducing the height of the chopped pillar. Essence Avoiding the depth and shape of the air (such as grooves or concave pits) can be adjusted according to demand to optimize spatial utilization and energy density.

Benefits of technology

By reducing the height of the pillars, the spatial utilization and energy density of the battery cells are improved, while reducing the adverse effects on the strength of the top cover.

Abstract

The embodiment of the utility model provides a battery cell, a battery, a top cover and electric equipment. The battery cell comprises a shell, a pole and a top cover; the shell is provided with an opening end; a mounting hole is formed in the top cover, and the top cover is connected to the opening end of the shell; the pole penetrates through the mounting hole and is connected with the top cover; the top cover is provided with a first side wall and a second side wall which are distributed on the two sides in the thickness direction, the first side wall is opposite to the shell, the second side wall faces the shell, a receding part which is sunken towards the second side wall is formed on the first side wall, and the upper end of the pole protrudes out of the first side wall. According to the battery cell, the battery, the top cover and the electric equipment provided by the embodiment of the invention, the clearance part is arranged to accommodate at least part of the bar, so that the required pole height is reduced, and the space utilization rate of the battery cell is improved.
