Abstract
An anode for a secondary battery capable of inserting and extracting a lithium ion having a multi-layered structure including a first anode layer containing carbon as a main component; a second anode layer made of a film-like material through which a lithium component passes; and a third anode layer containing lithium and/or a lithium-containing compound as a main component. The battery capacity of the lithium ion battery is substantially increased while the higher charge-discharge efficiency and the stable cycle performance are maintained.
