POWER STORAGE CELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18486982 titled 'POWER STORAGE CELL
Simplified Explanation
The power storage cell described in the patent application includes an electrode assembly, a cell case, and an external terminal. The cell case consists of a main body and a lid, with the lid being positively or negatively charged in the electrode assembly. The lid also contains a short-circuit member that can short-circuit the lid and the external terminal. The external terminal includes a terminal plate, and the short-circuit member is made of a conductive resin and is designed to separate from the terminal plate when the internal pressure of the cell case is below a certain threshold, but to come into contact with the terminal plate when the pressure exceeds that threshold.
- Electrode assembly
- Cell case with lid and short-circuit member
- External terminal with terminal plate
- Short-circuit member made of conductive resin
- Pressure-sensitive design for short-circuit member

Unanswered Questions
How does the conductive resin in the short-circuit member affect the overall performance of the power storage cell?
The conductive resin in the short-circuit member plays a crucial role in regulating the short-circuiting process based on internal pressure, but the specific impact on the cell's performance is not detailed in the patent application.
Are there any potential drawbacks or limitations to the pressure-sensitive design of the short-circuit member?
While the pressure-sensitive design is intended to enhance safety and efficiency, there may be certain conditions or scenarios where this feature could pose challenges or limitations that are not addressed in the patent application.
Original Abstract Submitted
A power storage cell includes an electrode assembly, a cell case, and an external terminal. The cell case has a case main body and a lid. The lid has a lid main body connected to an opening of the case main body and charged positively or negatively in the electrode assembly, and a short-circuit member connected to the lid main body, the short-circuit member being able to short-circuit the lid main body and the external terminal. The external terminal includes a terminal plate. The short-circuit member includes an elastic portion made of a conductive resin. The elastic portion is separated from the terminal plate when an internal pressure of the cell case is less than a predetermined pressure, and is elastically deformed to come into contact with the terminal plate when the internal pressure of the cell case is equal to or more than the predetermined pressure.
