ALL-SOLID-STATE LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an all-solid-state lithium secondary battery which uses as a collector a three-dimensional network porous body and whose internal resistance does not increase even when charging and discharging are repeated.SOLUTION: The all-solid-state lithium secondary battery includes a positive electrode, a negative electrode, and a solid electrolyte layer sandwiched between the positive electrode and the negative electrode. The positive electrode and/or the negative electrode is an electrode formed by using as a collector a sheet-like three-dimensional network porous body comprising a porous resin substrate and a metal coating formed on the surface of the porous resin substrate and by filling pores of the three-dimensional network porous body with at least an active material and a solid electrolyte.
