AbstractRechargeable aqueous zinc ion hybrid capacitors were developed in this work via engineering a Zn‐anode/electrolyte interface and 3D Graphene‐like Carbon Cathode. The designed hybrid device realizes the battery‐like specific energy (203 Wh kg–1) and supercapacitor‐type power capability (4.9 kW kg–1) and cycling stability (96.75% retention over 30000 cycles) at a much lower price than the commercial supercapacitors and Li‐ion batteries. This work (DOI: 10.1002/inf2.12344) provides a scalable yet cost‐effective approach for developing a next‐generation Zn‐ion‐based energy storage system.
