Layered transition-metal (TM) oxides have drawn ever-growing interest as positive electrode materials in potassium-ion batteries (PIBs). Nevertheless, the practical implementation of these is seriously hampered by their inferior cyclic property and rate performance. Reported here a self-templating strategy to prepare homogeneous P2-K0.6CoO2 (KCO) microcubes. Benefiting from unusual microcube architecture, interface between electrolyte active material considerably diminished. As result, KCO microcubes manifest boosted electrochemical properties for potassium storage including large reversible capacity (87.2 mAh g-1 under 20 mA g-1), superior performance, ultralong steady (an improved retention 86.9% 40 after 1000 cycles).
