Filed:
May 12, 2021
Appl. No.:
17/318268
Inventors:
- Irvine CA, US
Benjamin Yong Park - Mission Viejo CA, US
Sanjaya D. Perera - Irvine CA, US
Xuan-Dung Dang - Stevenson Ranch CA, US
Sung Won Choi - San Diego CA, US
International Classification:
H01M 50/46
H01M 4/505
H01M 4/134
H01M 4/525
H01M 50/403
H01M 10/0525
Abstract:
Systems and methods are provided for configuring cell performance using specific anode, cathode, and separator combinations. Separators with significant adhesive properties may be used in forming rechargeable cells, such as lithium-ion cells. The separator with significant adhesive properties may include an adhesive coating, applied on one or both sides of the separator, and/or adhesive material is dissolved or deposited within the separator. The separators with significant adhesive properties may also include one or more ceramic layers.

View page
US Patent:
20220367847, Nov 17, 2022
Filed:
May 13, 2021
Appl. No.:
17/319726
Inventors:
- Irvine CA, US
Jill Pestana - Irvine CA, US
Ian Browne - Irvine CA, US
Younes Ansari - Irvine CA, US
Sanjaya D. Perera - Irvine CA, US
International Classification:
H01M 4/134

H01M 4/1395
H01M 4/36
H01M 4/38
H01M 4/587
H01M 4/66
H01M 10/0525
Abstract:
A method and system for carbon-coated silicon in a pyrolyzed carbon binder electrode on copper current collectors may include providing a metal current collector; forming a non-porous carbon coating on the metal current collector; coating silicon particles with carbon; forming an active material layer on the metal current collector, where the active material layer comprises at least 50% silicon particles by weight and a carbon source; and pyrolyzing the active material layer on the metal current collector, with no silicon particles in contact with metal from the metal current collector. The metal current collector may include copper. The battery anode may include no copper-silicon eutectic. The silicon particles may range in size from 2 to 50 μm. The active material layer may include aluminum carbide. A source for the pyrolyzed carbon may include polyimide and/or polyamide-imide. The current collector may be coated with the non-porous carbon coating using physical vapor deposition.
