Title:
PRELITHIATED ANODE IN BATTERY CELLS FOR ELECTRIC VEHICLES
Document Type and Number:
WIPO Patent Application WO/2020/121288
Kind Code:
A8
Abstract:
Provided herein are systems, apparatuses, and methods of providing electrical energy for electric vehicles. A battery pack can be disposed in an electric vehicle to power the electric vehicle. A battery cell can be arranged in the battery pack. The battery cell can have a housing. The housing can define a cavity within the housing. The battery cell can have an electrolyte arranged within the cavity. The battery cell can have a cathode disposed within the cavity along one side of the electrolyte. The battery cell can have an anode disposed within the cavity along another side of the electrolyte. The anode can have a silicon-carbon structure. The silicon-carbon structure can be doped with lithium material prior to an initial charge cycle of the battery cell. The anode can have a negative electrode capacity 20–50% greater than a positive electrode capacity of the cathode.
