摘要

An electrode material for a rechargeable lithium battery, characterized in that said electrode material comprises a fine powder of a silicon-based material whose principal component is silicon element, said fine powder having an average particle size (R) in a range of 0.1 mum<=R<0.5 mum. An electrode structural body for a rechargeable lithium battery, having an electrode material layer comprising said silicon-based material fine powder. A rechargeable lithium battery whose anode comprising said electrode structural body.
