Vertically oriented graphene nanosheets are used to electrically bridge the current collector and active materials, enabling fluent charge transport in electrochemical energy storage devices. As reported by Zheng Bo, Zhenhai Wen, Xinliang Feng, and co‐workers on page 5799, the vertically oriented graphene‐bridged supercapacitors present excellent rate and power capabilities with a significantly reduced interfacial contact resistance.
