Problems solved by technology

In order to meet the requirements of battery overcurrent temperature rise, it is necessary to ensure that there is sufficient welding area between the first connecting plate and the tab, so that the first connecting plate needs to have sufficient size in the longitudinal direction of the battery cell, which will inevitably take up more space. Space, resulting in low space utilization of the cell and low energy density

Abstract

The invention discloses a rechargeable battery. The rechargeable battery comprises a battery cell and a connection component, wherein the battery cell comprises a battery cell main body and electrodelugs which extend out of the battery cell main body; the connection component comprises a guiding plate, and a first connecting plate and a second connecting plate respectively connected with the guiding plate; the guiding plate extends in the width direction; the first connecting plate extends toward the outer side of the guiding plate in the width direction; the electrode lugs are bent relativeto the longitudinal direction and are connected with the first connecting plate; at least a part of the guiding plate is protruded toward one side of the battery cell main body relative to the first connecting plate so as to form a protruding part; and the protruding part is abutted against the battery cell. According to the rechargeable battery disclosed by the invention, energy density can be improved.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a rechargeable battery. Background technique [0002] In the prior art prismatic rechargeable battery, the tabs of the battery cell are connected to the connecting member, and the first connecting plate connected to the battery cell in the connecting member is generally parallel to the longitudinal direction of the battery cell. With the continuous expansion of the market, more and more batteries with higher current are required. In order to meet the requirements of battery overcurrent temperature rise, it is necessary to ensure that there is a sufficient welding area between the first connecting plate and the tab, so that the first connecting plate needs to have sufficient size in the longitudinal direction of the battery cell, which will inevitably take up more space. As a result, the space utilization rate of the battery cell is not high, and the energy density is...
