摘　　要：单一电极材料很难满足高性能超级电容器的需求。为开发兼具氧化物和碳材料优点的电极材料,本文通过氧化Co/Ni混合配合物先驱体,得到一种堆积紧密的Ni Co2O4/C&S纳米复合材料。对该复合物的结构、组成和电化学性质进行了表征分析。用于超级电容器电极材料时,该复合物展示出超长的冲/放电稳定性(>20000圈)。该复合物循环寿命的提高,得益于它的超高稳定性。本文探讨了C和S对形成这种稳定结构的作用。Single-material electrodes do not satisfy the demands of high-performance supercapacitors.To exploit the advantages of both oxides and carbon-based materials,a tightly packed NiCo 2O 4/C&S nanocomposite was fabricated by sintering a Co/Ni-based coordination complex precursor.The composites and basic components were characterized by using various techniques.When used as supercapacitor electrodes,the synthesized composites showed extra-long cycling stability(>20000 cycles)during the charge/discharge process.This improvement in the cycle life of the composites was attributed to its highly stable structure.The roles of C and S in forming a stable structure were investigated.
