We report the successful fabrication of a micro-pseudocapacitor based on ternary nickel cobalt sulfide for the first time, with performance substantially exceeding that of previously reported micro-pseudocapacitors based on binary sulfides. CoNi2S4 micro-pseudocapacitor exhibits a maximum energy density of 18.7 mWh/cm3 at a power density of 1163 mW/cm3, opens up an avenue for exploring new family of ternary oxides/sulfides based micro-pseudocapacitors.​
