Abstract
An electrode for a non-aqueous electrolyte secondary battery to be embodied in both the anode and cathode. It comprises a mixture including, an active material having reversibility for charging and discharging, and a whisker which is chemically and electrochemically inert. Said active material is a substance capable of reversibly intercalating and deintercalating lithium. Said mixture includes a binding agent and constitutes a solid structural body. Said whisker is at least one selected from the group consisting of silicon carbide whisker, silicon nitride whisker, potassium titanate whisker and aluminum borate whisker.
