Power Storage Cell - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240258578 titled 'Power Storage Cell
The patent application describes a power storage cell comprising a cell case, a wound electrode assembly, and an electrolyte solution. The cell case houses the wound electrode assembly and the electrolyte solution, which includes a positive electrode sheet, a separator sheet, and a negative electrode sheet wound together.
- The wound electrode assembly has a first end portion facing a top wall and a second end portion located opposite to the first end portion.
- At both the first end portion and the second end portion, the separator sheet extends outward with respect to the negative electrode sheet.
- The separator sheet has a longer protruding length at the first end portion compared to the second end portion.
Potential Applications: - Energy storage systems - Electric vehicles - Portable electronic devices
Problems Solved: - Efficient energy storage - Enhanced battery performance - Improved safety in power storage devices
Benefits: - Increased energy density - Longer battery life - Enhanced overall performance
Commercial Applications: Title: Advanced Power Storage Cells for Sustainable Energy Solutions This technology can be utilized in various industries such as renewable energy, automotive, and consumer electronics, leading to more efficient and sustainable power storage solutions.
Questions about the technology: 1. How does the design of the wound electrode assembly contribute to the overall performance of the power storage cell? 2. What are the potential challenges in scaling up the production of these advanced power storage cells for commercial applications?
Original Abstract Submitted
a power storage cell includes a cell case, a wound electrode assembly, and an electrolyte solution. the cell case houses the wound electrode assembly and the electrolyte solution. the wound electrode assembly includes a positive electrode sheet, a separator sheet, and a negative electrode sheet. in a winding axis direction, the wound electrode assembly has a first end portion and a second end portion. the first end portion faces a top wall. the second end portion is located opposite to the first end portion. at both the first end portion and the second end portion, the separator sheet extends outward with respect to the negative electrode sheet. at the first end portion, the separator sheet has a first protruding length. at the second end portion, the separator sheet has a second protruding length. the first protruding length is longer than the second protruding length.
