An energy storage device, comprising: two electrodes; and an isolation layer, which is arranged between the electrodes; wherein at least one of the electrodes and the isolation layer includes a copolymer polymer, the copolymer polymer It is used as a non-aqueous adhesive and/or solid electrolyte of the energy storage device, used in the electrode or isolation layer, and the copolymer is a copolymer formed by the polymerization reaction of acrylonitrile and vinyl acetate or its derivative. Thereby, the energy storage device using the copolymer polymer can have better charging and discharging properties, and the efficiency and life of the energy storage device can be effectively extended. |
