A high‐performance lithium‐ion capacitors (LIC) based on two dimensional nanosheet materials, made of ZnMn 2 O 4 ‐graphene (ZMO‐G) hybrid nanosheets anode and N‐doped carbon nanosheets (NCN) cathode is realized by P. S. Lee and co‐workers in article number 1602893. The fabricated LIC delivers a high specific energy of 202.8 Wh kg −1 at a power of 180 W kg −1 , the specific energy can still remain 98 Wh kg −1 even when the power density reaches as high as 21 kW kg −1 .
