摘　　要：通过测定碳电极和镉电极的析氢析氧电位来确定镉电极和碳负极并联的可行性。对实验样品进行容量、功率和循环寿命测试,实验证明镉电极与碳电极进行并联后可以大幅提升镍碳超级电容器的容量,同时功率性能变化很小。但是由于镉电极的寿命下降较快,5 000次循环以后实验产品的容量衰降为初始值的60%。The feasibility of Cd electrode and carbon negative electrode in parallel connection was analyzed, by measuring the hydrogen and oxygen evolution potential of carbon electrode and Cd electrode respectively. Then, the capacity, power and cycle life of the test Ni-C super-capacitor was measured. The test results certify that the capacity of Ni-C super-capacitor can be raised greatly, while the power of the test Ni-C super-capacitor appears only a little change. But the capacity of the test Ni-C super-capacitor declines to 60% of the primary capacity after 5 000 cycles due to the marked decline of Cd electrode.
