Title:
ELECTROLYTES FOR LITHIUM-ION BATTERY CELLS WITH VOLUME-CHANGING ANODE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/126139
Kind Code:
A3
Abstract:
A Li-ion battery cell includes anode and cathode electrodes, a separator electrically separating the anode electrode and the cathode electrode, and an electrolyte ionically coupling the anode electrode and the cathode electrode. In some designs, the anode electrode has a capacity loading in the range of about 2 mAh/cm2 to about 10 mAh/cm2 and includes anode particles that (i) have an average particle size in the range of about 0.2 microns to about 20 microns, (ii) exhibit a volume expansion in the range of about 8 vol. % to about 180 vol. % during one or more charge-discharge cycles of the battery cell, and (iii) exhibit a specific capacity in the range of about 800 mAh/g to about 3000 mAh/g.
