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.
一种储能装置包括两个电极;以及设置在电极之间的隔板;其中,电极和隔板中至少有一个包括共聚物,共聚物用作储能装置电极和隔板的非
水粘合剂和/或固体电解质,共聚物是
丙烯腈和
醋酸乙烯聚合反应形成的共聚产物或其衍
生物。因此,使用该共聚物的储能装置的充放电性能可以得到改善,从而有效延长储能装置的效率和使用寿命。
