• Following the fast growth of micro-energy storage devices, there is an urgent need to develop miniaturized electronic devices with excellent performance that are both green and safe. Planar interdigitated rechargeable Zn microbatteries（MBs） have gained widespread attention in recent years due to their ease of series-parallel integration, mechanical flexibility and no need for traditional separators. We prepared a patterned cathode of NiCo layered double hydroxide（LDH）@indium tin oxide（ITO） nanowires（NWs） @carbon cloth（CC） by the chemical vapor deposition of ITO NWs on the carbon fibers in a CC, laser patterning, and finally the electrodeposition of NiCo-LDH to coat the ITO NW@carbon fibers. The cathode was combined with a patterned Zn foil anode to form a planar MB. Because of the highly conductive ITO NWs@CC current collector, the interdigitated MB had a satisfactory performance. The planar MB has a high specific capacity of 453.5 mAh g-1(corresponding to 0.56 mAh cm-2) in an alkaline water-based electrolyte
