【摘要】 钼酸镍（NiMoO₄）复合材料具有稳定的晶体构造、较高的导电性能，以碳布作为基底制备了NiMoO₄@CC//Fe₂O₃非对称超级电容器，经过电化学测试表明，其具有不错的稳定性和良好的倍率性能，同时还有较高的功率密度，在功率密度为805μW·cm^-2时，器件的能量密度是6.76μW·h·cm^-2。此外，用石墨烯和硅橡胶制备了能够收集能量的摩擦纳米发电机（GO-TENG）,通过测试发现，其开路电压可以稳定在100 V左右，短路电流大约为6μA,瞬时功率约为450μW,并且在长时间的测试中其性能没有下降，证明其具有良好的稳定性能。将两者组合在一起形成一个自供电装置，TENG收集的能量可以在超级电容器中储存，需要时对外部供电。更多还原

【Abstract】 The nickel molybdate（NiMoO₄） composite material has stable crystal structure and high electrical conductivity. We prepared the NiMoO₄@CC//Fe₂O₃ asymmetric supercapacitor on the basis of carbon cloth. The electrochemical test shows that it has good stability, good multiplier performance, and high power density. When the power density is 805 μW·cm^-2, the energy density is 6.76 μW·h·cm^-2. In addition, a friction nanogenerator（GO-TENG） was prepared using graphene and silicone rubber to collect energy. It was found that the open-circuit voltage, short-circuit current and instantaneous power of Go-TENG can be stabilized at about 100 V, about 6 μA and 450 μW, and the performance of Go-TENG is not decreased during the test, which proves that the good stability performance. Combining the two to form a self-powered device, the energy collected by the TENG can be stored in a supercapacitor to supply external power when needed.更多还原
