PROBLEM TO BE SOLVED: To provide an electrode for an electrochemical energy storage system with a large potential domain, a high stability at high temperature, and a property of improving electrolyte penetration. An energy storage system (120) includes an anode (121), a cathode (122) disposed near the anode (121) but not in contact, a non-aqueous electrolyte (124) in which the anode (121) and the cathode (122) are immersed, and an electrolyte (124). A hermetic container 125 that accommodates the anode 121 and the cathode 122 is provided. The anode 121 is a porous matrix having a plurality of micrometer-sized pores, a porous matrix that is a three-dimensional mesoporous metal or a three-dimensional open structure carbonaceous material, and a nano-layer that covers the inside of the pores. Metal oxide with a structure. The electrolytic solution 124 includes an organic salt having an acylamino group and a lithium salt represented by LiX, where X is ClO 4 − , SCN − , PF 6 − , B (C 2 O 4 ) 2 − , N ( SO 2 CF 3 ) 2 − , CF 3 SO 3 − , or combinations thereof.
