摘要:
The present invention relates to a process for producing an anode for a secondary battery, which is capable to reduce a contact resistance between a sintered material which contains silicon as an anode active material and a current collector. A binder and a solvent are mixed with a silicon-containing anode material to prepare a slurry. A base material made of a foil or mesh of conductive metal is coated with the slurry, and the solvent is removed to form a coated film. The coated film is sintered in a non-oxidizing atmosphere, thereby integrating a sintered material of the coated film with the base material.
