ALL-SOLID STATE LITHIUM ION SECONDARY BATTERY

PROBLEM TO BE SOLVED: To provide an all-solid state lithium ion secondary battery capable of fast charging and discharging while maintaining high capacity.SOLUTION: The all-solid state lithium secondary battery is composed of a plurality of power generating elements with a cathode 1, solid electrolyte 2 and an anode 3 sequentially laminated connected in series through collectors 4. At least one electrode out of the cathode 1 and the anode 3 has a plurality of through-holes 7 in a thickness direction of the electrodes 1, 3, and an ionic conductive layer 9 is formed on an inner wall surface of each through-hole 7. Thereby, the ions in the electrodes 1, 3 flow well to the ionic conductive layer 9 in the through-hole 7 to improve the electron conductivity in the electrodes 1, 3. Since ions well transfer in the ionic conduction layer 9, high-speed charging and discharging become possible while maintaining high capacity.
