A novel supercapacitor electrode composed of multicomponent MnCo 2 O 4 @Ni(OH) 2 belt‐based core‐shell nanoflowers is reported by L. M. Wu and co‐workers on page 4085. This hybrid electrode exhibits ultrahigh specific capacitance and its asymmetric supercapacitor device also displays excellent electrochemical performance in terms of energy density, power density and cycling lifespan, which excel most of the previous reported nickel, cobalt, manganese oxides/hydroxides.
