Lithium‐ion hybrid electrochemical capacitors (Li‐HSCs) are reported by Zhen Zhou and co‐workers in article number 1500550. MnO nanoparticles are dispersed on graphene as battery‐type anodes, and ultrathin N‐doped porous carbon materials are used as capacitor cathodes. These Li‐HSCs approach the level of energy density seen in Li‐ion batteries, while maintaining supercapacitors' power density.
