Abstract
An anode component for a lithium-ion cell is formed using an atmospheric plasma deposition. The anode component has an anode material layer comprising high lithium-intercalating capacity silicon particles as active anode material in pores of a bonded layer of metal particles. The atmospheric plasma deposition process deposits metal particles and smaller silicon-containing particles concurrently or sequentially on an anode current collector substrate or polymeric separator substrate for the lithium-ion cell. The anode material layer may optionally be lithiated in the atmospheric plasma deposition process. The plasma deposition process is used to form a porous electrode layer on the substrate consisting essentially of a porous metal matrix containing smaller particles of the electrode material particles supported and carried in the pores of the matrix. When the anode component is assembled into a cell, remaining pore capacity is filled with a lithium-ion containing liquid electrolyte solution.
