Abstract
A negative electrode for lithium secondary battery characterized in that the electrode is obtained by sintering a mixture of an active material alloy and a binder disposed on a current collector, or a mixture of an active material alloy, conductive metal powder and a binder disposed on a current collector, and the active material alloy after sintered is substantially amorphous.
Claims18
A negative electrode for lithium secondary battery, said negative electrode being obtained by sintering a mixture of an active material alloy and a binder arranged on a current collector made of metallic foil, or sintering a mixture of an active material alloy, conductive metal powder and a binder arranged on a current collector made of metallic foil,
- wherein said active material alloy after said sintering process is substantially amorphous.
A manufacturing method of a negative electrode for lithium secondary battery, comprising the steps of:
- disposing a mixture of an active material alloy which is substantially amorphous and a binder, or a mixture of said active material alloy, conductive metal powder and a binder, on a current collector made of metallic foil;
- and
- sintering said mixture under a condition such that said active material alloy is substantially amorphous after sintered.
