Abstract
A method for preparing an electrode material for a lithium battery, characterized in that a noncrystalline silicon thin film that serves as an active material is deposited on a substrate.
Claims19
A method for constructing a rechargeable lithium battery comprising:
- pretreating a surface of a current collector by plasma or ion irradiation;
- depositing on said pretreated current collector a thin film of active material that is alloyable with lithium by a thin-film forming process which supplies raw material from a vapor phase, to fabricate an electrode;
- forming a negative electrode from said electrode;
- and
- assembling said negative electrode, a positive electrode and an electrolyte into a rechargeable lithium battery.
