Abstract Based on the spontaneous redox reaction between metal and graphene oxide, a novel type of metal/graphene oxide (M/GO) batteries is developed to convert chemical energy into electricity, including Li/GO, Na/GO, Zn/GO, Fe/GO, and Cu/GO batteries. They are fabricated via the simple assembly of metal foils with GO films, in which M plays the role of anode, and GO acts as both cathode and separator. Among them, Li/GO battery generates the highest specific capacity of 1572 mAh cm −3 (about 1604 mAh g −1 ). The energy density of M/GO battery is determined by the contact area of M with GO. Therefore, three-dimensional (3D) M/GO battery will deliver higher energy in comparison to 2D planar M/GO battery. As expected, a semi-solid 3D-Cu/GO redox flow battery (RFB) is assembled by 3D Cu foam with flowing GO/ionic-liquid catholyte. Its specific capacity is ca. 97 times that of Cu foil/GO RFB. Besides, a compressible, all-solid-state, and pressure-responsive 3D-GO/Zn battery is also fabricated. It can accurately control the energy output in response to pressure stimulations without the aid of conventional battery management system. Beyond those demonstrated in this work, the concept of M/GO battery will shed light on the design of similar electrochemical power sources.

金属/氧化石墨烯电池

摘要 基于金属和氧化石墨烯之间的自发氧化还原反应，开发了一种新型的金属/氧化石墨烯（M/GO）电池，将化学能转化为电能，包括 Li/GO、Na/GO、Zn/GO、Fe /GO 和 Cu/GO 电池。它们是通过金属箔与 GO 薄膜的简单组装制造的，其中 M 充当阳极，而 GO 充当阴极和隔膜。其中，Li/GO电池产生的最高比容量为1572 mAh cm -3 (约1604 mAh g -1 )。M/GO电池的能量密度由M与GO的接触面积决定。因此，与二维平面 M/GO 电池相比，三维 (3D) M/GO 电池将提供更高的能量。正如预期的那样，半固体 3D-Cu/GO 氧化还原液流电池 (RFB) 由 3D Cu 泡沫与流动的 GO/离子液体阴极电解液组装而成。它的比容量是大约。是铜箔/GO RFB 的 97 倍。此外，还制备了可压缩、全固态和压力响应的 3D-GO/Zn 电池。它可以根据压力刺激准确控制能量输出，而无需借助传统的电池管理系统。除了在这项工作中展示的那些之外，M/GO 电池的概念将阐明类似电化学电源的设计。
