In this work, we report the fabrication of flexible two-dimensional Ni（OH）2 nanoplates-based MSCs, which achieved a specific capacitance of 8.80 F/cm^3 at the scan rates of 100 mV/s, losing only 0.20% of its original value after 10,000 charge/discharge cycles. Besides, the MSCs reached an energy density of 0.59 mWh/cm^3 and a power density up to 1.80 W/cm^3, which is comparable to traditional carbon-based devices. The flexible MSCs exhibited good electrochemical stability when subjected to bending at various conditions, illustrating the promising application as electrodes for wearable energy storage.展开更多
