Abstract:
A method and apparatus for fabricating electrodes used in energy storage devices are provided. In some implementations a surface of the electrode is activated for (a) a pre-treatment process to remove loosely held particles from the electrode surface; (b) a pre-treatment process to activate the surface of the electrode material for improved bonding or wetting for subsequently deposited materials; (c) a post-treatment of the pre-lithiation layer to improve subsequent bonding with additionally deposited layer, for example, passivation layers; and/or (d) a post-treatment of the pre-lithiation layer to improve/accelerate absorption of the lithium into the underlying electrode material.
