AI Technical Summary
Technical Problem
Existing battery cell pressurizing members fail to effectively pressurize the short side of the cup portion due to their flat shape, leading to residual gas and requiring manual height adjustments of protrusions, which is time-consuming and labor-intensive.
Method used
A battery cell pressurizing member with a protrusion made of shape memory material that adjusts its height in response to pressure and temperature changes, allowing automatic adaptation to the cell's thickness without manual intervention.
Benefits of technology
The shape memory material-based protrusion ensures efficient gas discharge from the battery cell by dynamically adjusting its height, reducing manual labor and time consumption, and minimizing cell damage.

Abstract
The present invention relates to a battery cell pressing member comprising: a pressing pad for pressing one surface of a cup part of a battery cell; and a protrusion part formed on one surface of the pressing pad so as to press an edge of the cup part, wherein the protrusion part is made of a shape memory material, and the height thereof is changed by a change in pressure, temperature, or both.
