An energy storage device comprises two electrodes; and a separator disposed between the electrodes; wherein at least one of the electrodes and the separator comprises a copolymer, which serves as a non-aqueous binder and/or solid electrolyte for the electrodes and the separator of the energy storage device, and the copolymer is a copolymerized product or its derivative formed by the polymerization reaction of acrylonitrile and vinyl acetate. Therefore, the charge and discharge properties of the energy storage device using the copolymer can be improved, thereby effectively extending the efficiency and lifetime of the energy storage device.

Energy storage device

An energy storage device includes an anode, a cathode, and a separator disposed between the anode and the cathode. At least one of the anode, cathode and separator includes a copolymer functioning as a non-aqueous adhesive and/or solid-state electrolyte for the energy storage device. The copolymer is a copolymer or a derivative thereof, which is produced by polymerization of monomers containing conductive ion group and/or olefinic monomers in the presence of 2-propenenitrile. Therefore, the energy storage device which the copolymer is used therein has excellent charging and discharging performance to therefore effectively enhance the efficiency and extend the service life of the energy storage device.

An energy storage device has an anode, a cathode and an electrolyte membrane, installed in between the anode and the cathode, wherein at least one of the anode, the cathode and the electrolyte membrane is incorporated with a copolymer and the copolymer is grafted to a functional group with ionic conductive function. Therefore, the energy storage device, which utilizes copolymers and electrolyte membranes, has better efficiency of charge/discharge performance; thus the efficiency thereof increases; the lifetime thereof is prolonged effectively.
