Abstract
A negative electrode for non-aqueous electrolyte secondary batteries has a mixture layer disposed on a current collector. The mixture layer includes a composite negative electrode active material, a first binder containing an acryl-group-containing polymer, and a second binder containing adhesive rubber particles. The composite negative electrode active material contains carbon nanofibers, a catalyst element, and silicon-containing particles capable of charging and discharging at least lithium ions. The first binder binds the silicon-containing particles to the current collector, and the second binder binds the carbon nanofibers together.
