摘要:
The present invention is intended to provide an anode for a nonaqueous electrolyte secondary cell that can improve the cycle characteristics. In the anode for a nonaqueous electrolyte secondary cell, by modifying the surface of an active material with a polymer containing a carboxyl group, followed by bonding to a crosslinking binder, a stable SEI layer is formed and thus a mixture layer with high mechanical strength is provided, thereby preventing detachment of the active material due to a volume change caused by charging and discharging, and thus providing an electrode for a secondary cell with good cycle characteristics.
