LITHIUM CYLINDRICAL CELL CONFIGURED FOR DIRECT ELECTRODE-SEPARATOR CONTACT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240055728 titled 'LITHIUM CYLINDRICAL CELL CONFIGURED FOR DIRECT ELECTRODE-SEPARATOR CONTACT
Simplified Explanation
The patent application describes a lithium-sulfur cylindrical cell with a unique jelly roll design.
- The cell consists of a cylindrical shell with an inner volume.
- A jelly roll is placed inside the inner volume, containing a freestanding lithium anode and a sulfur cathode.
- A first separator separates the anode and cathode on one side of the jelly roll.
- In cylindrical cell formats, a windable second separator is used in the jelly roll.
- The second separator may come in direct contact with both sides of the anode and cathode as the jelly roll is wound.
- Potential Applications:**
- Energy storage systems
- Electric vehicles
- Portable electronic devices
- Problems Solved:**
- Increased energy density
- Longer cycle life
- Enhanced safety
- Benefits:**
- Higher energy density
- Longer cycle life
- Improved safety features
Original Abstract Submitted
a lithium-sulfur cylindrical cell. the cell includes a cylindrical shell defining an inner volume, and a jelly roll disposed within the inner volume. the jelly roll includes an anode comprising lithium, where the anode is configured as a freestanding assembly. additionally, the jelly roll comprises a cathode comprising sulfur. further, the jelly roll comprises a first separator between a first side of the anode and a first side of the cathode. in cylindrical cell formats, the jelly roll comprises a windable second separator. as the jelly roll is wound, the second separator may come in direct contact with both a second side of the anode and with a second side of the cathode. alternatively, as the jelly roll is wound, the second separator may come in direct contact with the second side of the anode and with a cathode current collector.
