摘要

High performance anode materials are required for the development of stable, efficient and low cost energy storage devices. ZrO2 is a stable electrode material. However, its electrochemical performance is poor. Thus, in the present study we have synthesized ZrO2@MoO3 as an anode material using hydrothermal method and studied its electrochemical behaviour. The specific capacitance (SC) of the ZrO2@MoO3 turns out to be 916 F/g at 3.3 A/g. The electrode retains 90% of its initial SC after 2000 cycles. To test the real life application of the ZrO2@MoO3 as an anode material, asymmetric device was assembled using activated carbon (AC) as a cathode (ZrO2@MoO3//AC). The energy density and power density of ZrO2@MoO3//AC turns out to be 15 Wh/kg and 933 W/Kg, respectively. After 30 s of charging, ZrO2@MoO3//AC is used to light up two light emitting diodes (LEDs) for 6 mins.
