Abstract
A pre-lithiated silicon-based anode includes a silicon-based anode, lithium disposed on a surface or in an interior of the silicon-based anode, and a protective coating on the surface of the silicon-based anode. The pre-lithiated silicon-based anode allows subsequent processing to be performed safely in the atmosphere.
