ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY, AND ELECTRICAL APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18353679 titled 'ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY, AND ELECTRICAL APPARATUS

Simplified Explanation

The patent application describes an electrode assembly used in batteries or energy storage devices.

  • The electrode assembly includes a first electrode sheet, a second electrode sheet, and a first separator.
  • The first and second electrode sheets have opposite polarities and are separated by the first separator.
  • The assembly is wound in a specific direction.
  • There is a bending region in the assembly.
  • A second separator is added in the bending region to further separate the electrode sheets.
  • Ions deintercalated from the first electrode sheet can pass through both separators and be intercalated in the second electrode sheet.


Original Abstract Submitted

An electrode assembly includes a first electrode sheet, a second electrode sheet, and a first separator. The first electrode sheet and second electrode sheet are of opposite polarities, the first separator is configured to separate the first electrode sheet and the second electrode sheet. The first electrode sheet, the second electrode sheet, and the first separator are wound in a winding direction. The electrode assembly has a bending region. The bending region is provided with a second separator that is laminated with the first separator and configured to separate the first electrode sheet and the second electrode sheet adjacent to each other. At least part of ions deintercalated from the first electrode sheet are able to pass through the first separator and the second separator and be intercalated in the second electrode sheet.
