Herein, we propose an advanced energy-storage system: all-graphene-battery. It operates based on fast surface-reactions in both electrodes, thus delivering a remarkably high power density of 6,450 W kg(-1)(total electrode) while also retaining a high energy density of 225 Wh kg(-1)(total electrode), which is comparable to that of conventional lithium ion battery. The performance and operating mechanism of all-graphene-battery resemble those of both supercapacitors and batteries, thereby blurring the conventional distinction between supercapacitors and batteries. This work demonstrates that the energy storage system made with carbonaceous materials in both the anode and cathode are promising alternative energy-storage devices.
在此，我们提出一种先进的储能系统：全石墨烯电池。它基于两个电极中的快速表面反应运行，因此在总电极方面可提供高达6450 W kg⁻¹的显著高功率密度，同时还能保持225 Wh kg⁻¹（总电极）的高能量密度，这与传统锂离子电池相当。全石墨烯电池的性能和运行机制类似于超级电容器和电池，从而模糊了超级电容器和电池之间的传统区别。这项工作表明，在阳极和阴极均采用碳质材料制成的储能系统是很有前景的替代储能装置。
