POWER STORAGE CELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240128617 titled 'POWER STORAGE CELL
Simplified Explanation
A power storage cell includes an electrode assembly, a cell case, and an external terminal. The cell case consists of a case main body and a lid. The lid is connected to an opening of the case main body and is charged positively or negatively in the electrode assembly. Additionally, the lid has a short-circuit member connected to it, which can short-circuit the lid main body and the external terminal. The external terminal comprises a terminal plate. The short-circuit member includes an elastic portion made of a conductive resin. This elastic portion is separated from the terminal plate when the internal pressure of the cell case is less than a predetermined pressure, and it 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.

Unanswered Questions
How does the elastic portion maintain conductivity over multiple cycles of deformation and contact with the terminal plate?
The elastic portion is made of a conductive resin, but it is unclear how it retains its conductivity properties over numerous cycles of deformation and contact with the terminal plate. Further research and testing may be needed to address this question.
What is the impact of temperature fluctuations on the performance of the short-circuit member in the power storage cell?
Temperature variations can affect the elasticity and conductivity of the short-circuit member. Understanding the temperature sensitivity of the technology is crucial for its practical application in different environments.
