Title:
SECONDARY BATTERY CELL
Document Type and Number:
WIPO Patent Application WO/2018/095170
Kind Code:
A1
Abstract:
The application relates to the field of secondary batteries, and specifically, to a secondary battery cell. The secondary battery cell comprises: a first adaptation plate, a second adaptation plate, and a battery cell. The battery cell comprises first electrode plates, second electrode plates, first electrode tabs, and second electrode tabs. The first electrode tabs are arranged at two or more of the first electrode plates. The first electrode tabs are stacked in layer to form a first multi-electrode tab structure connected to the first adaptation plate. The first multi-electrode tab structure is connected to the first adaptation plate to form a first adaptation component. At most one layer of the first adaptation component is provided along a direction in parallel to the first electrode plates. The application is utilized to effectively reduce spatial wastage in a conventional bent electrode tab at a battery top portion, providing more stable bending, and increasing battery energy density.
