摘　　要：钼酸镍(NiMoO_(4))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NiMoO_(4)@CC//Fe_(2)O_(3)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。The nickel molybdate(NiMoO_(4))composite material has stable crystal structure and high electrical conductivity.We prepared the NiMoO_(4)@CC//Fe_(2)O_(3) 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 805μW·cm^(-2),the energy density is 6.76μW·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 6μA and 450μW,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.
