文摘

The NiCo2S4-HL nanomaterial is achieved via two-step hydrothermal approach. The unique structures are assembled self-assembly by nanosheets. The obtained electrode exhibits high capacitance and excellent retention. An asymmetric supercapacitor also displays high energy density and outstanding cycling stability. The high-performance of the device is possibly due to the introduction of HL and formation of composed nanosheets.
