A recently filed patent (Publication Number: US20230207947A1) describes a new design for a battery that aims to enhance its strength and binding force. The battery consists of multiple battery cells, with each cell having a wall parallel to a horizontal plane. The binding component of the battery is designed to accommodate and bind the battery cells together.

One key feature of the design is the inclusion of a reinforcing portion in the binding component. This reinforcing portion is positioned parallel to the wall with the largest area of each battery cell, and its purpose is to strengthen the binding component and enhance its binding force to the walls with the largest area of the battery cells.

The patent also mentions that the reinforcing portion can be provided in regions between adjacent battery cells and/or between the battery cells and the binding component. The binding component itself consists of an upper cover and a lower case, with the reinforcing portion being present in either or both of these components.

The reinforcing portion is integrally molded with the binding component and protrudes away from the battery cells. A recess is formed on the surface of the binding component close to the battery cells, opposite to the reinforcing portion. The patent suggests that the upper cover and lower case can both have reinforcing portions, which are positioned correspondingly in a vertical direction. The region between these reinforcing portions is filled with an adhesive to connect them.

The battery cells themselves have an end cover and a housing, with an R angle provided at the bottom of the housing away from the end cover. This R angle is covered by the adhesive.

The patent also describes various configurations for the electrode assembly of the battery cells, including a winding structure, stacked sheets, and bent segments.

The patent further includes claims related to the manufacturing of the battery and a device for manufacturing the battery.

Overall, this patent proposes a battery design with a reinforcing portion in the binding component to enhance its strength and binding force. The design aims to improve the overall performance and durability of the battery.
