A surface-modified Co3O4 ultrathin nanosheet (denoted as PCO) is reported via controllable phosphate ion functionalization for pseudocapacitors. An energy density of 71.6 W h kg−1 (at 1500 kg−1) achieved by the PCO-based pseudocapacitor. The unique porous morphology, high surface reactivity, and fast electrode kinetics PCO are found to be responsible enhanced pseudocapacitive performance.
