LITHIUM CYLINDRICAL CELL CONFIGURED FOR DIRECT ELECTRODE-SEPARATOR CONTACT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240055727 titled 'LITHIUM CYLINDRICAL CELL CONFIGURED FOR DIRECT ELECTRODE-SEPARATOR CONTACT

Simplified Explanation

The patent application describes a lithium-sulfur cylindrical cell with a jelly roll structure, where the anode is a freestanding assembly and the cathode is made of sulfur.

  • The cell includes a cylindrical shell and a jelly roll inside it.
  • The jelly roll consists of a lithium anode and a sulfur cathode.
  • A first separator is placed between the anode and cathode.
  • In cylindrical cell formats, a windable second separator is used.
  • The second separator may come in direct contact with both sides of the anode and cathode as the jelly roll is wound.

  • Reduced cost of energy storage
      1. Benefits
  • Higher energy density
  • Longer cycle life
  • Potentially lower cost of energy storage
  • Suitable for various applications due to cylindrical cell format


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.
