As an energy storage device, supercapacitors are practically used in many fields due to their high power density and long service life. Among the components of supercapacitors, electrode materials play a key role in the performance of the device, it is thus of great significance to prepare electrode materials with superior electrochemical performance. NiCo2S4 was prepared by a hydrothermal method using nickel acetate and cobalt acetate as raw materials, glutathione as a morphology control agent and a sulfur source. The effect of hydrothermal reaction time on the microstructure, morphology and electrochemical performance of NiCo2S4 was investigated. The results show that the NiCo2S4 material prepared under the action of glutathione has a yolk-shell structure. The specific capacitance is 1 552.7 F/g when the current density is 0.5 A/g, and the specific capacitance can be maintained at 61.3% at 10 A/g. After 2 000 cycles, the specific capacitance retention of the material can be maintained at 79.3%. A supercapacitor can be assembled with NiCo2S4 and activated carbon as positive and negative electrodes, respectively. This hybrid supercapacitor can provide 33.9 W·h/kg energy density when the power density is 800 W/kg. After 2 000 charge and discharge cycles, the specific capacitance retention rate is 89%.

超级电容器作为一种新型储能器件,凭借其高功率密度和超长的使用寿命等优点,已被实际应用于多个领域。在超级电容器组成部件中,电极材料对器件性能优劣起着关键作用,因此制备电化学性能优异的电极材料具有重要意义。采用乙酸镍、乙酸钴为原料,还原型谷胱甘肽(GSH)为形貌控制剂和硫源,通过水热法制备NiCo2S4电极材料,并研究了水热反应时间对NiCo2S4微观结构、形貌、电化学性能的影响。结果表明:在GSH作用下制备的NiCo2S4材料呈现“蛋黄-蛋壳”结构;当电流密度为0.5 A/g时,比电容为1 552.7 F/g;在电流密度为10 A/g条件下可以保持61.3%的比电容;经过2 000次循环后,NiCo2S4电极材料的比电容保持率可以维持在79.3%。分别以NiCo2S4与活性炭为正负极组装一个混合型超级电容器,在功率密度为800 W/kg时可以提供33.9 W·h/kg能量密度,在2 000次充放电循环后样品的比电容保持率为89%。

超级电容器作为一种新型储能器件,凭借其高功率密度和超长的使用寿命等优点,已被实际应用于多个领域。在超级电容器组成部件中,电极材料对器件性能优劣起着关键作用,因此制备电化学性能优异的电极材料具有重要意义。采用乙酸镍、乙酸钴为原料,还原型谷胱甘肽(GSH)为形貌控制剂和硫源,通过水热法制备NiCo2S4电极材料,并研究了水热反应时间对NiCo2S4微观结构、形貌、电化学性能的影响。结果表明:在GSH作用下制备的NiCo2S4材料呈现“蛋黄-蛋壳”结构;当电流密度为0.5 A/g时,比电容为1 552.7 F/g;在电流密度为10 A/g条件下可以保持61.3%的比电容;经过2 000次循环后,NiCo2S4电极材料的比电容保持率可以维持在79.3%。分别以NiCo2S4与活性炭为正负极组装一个混合型超级电容器,在功率密度为800 W/kg时可以提供33.9 W·h/kg能量密度,在2 000次充放电循环后样品的比电容保持率为89%。

As an energy storage device, supercapacitors are practically used in many fields due to their high power density and long service life. Among the components of supercapacitors, electrode materials play a key role in the performance of the device, it is thus of great significance to prepare electrode materials with superior electrochemical performance. NiCo2S4 was prepared by a hydrothermal method using nickel acetate and cobalt acetate as raw materials, glutathione as a morphology control agent and a sulfur source. The effect of hydrothermal reaction time on the microstructure, morphology and electrochemical performance of NiCo2S4 was investigated. The results show that the NiCo2S4 material prepared under the action of glutathione has a yolk-shell structure. The specific capacitance is 1 552.7 F/g when the current density is 0.5 A/g, and the specific capacitance can be maintained at 61.3% at 10 A/g. After 2 000 cycles, the specific capacitance retention of the material can be maintained at 79.3%. A supercapacitor can be assembled with NiCo2S4 and activated carbon as positive and negative electrodes, respectively. This hybrid supercapacitor can provide 33.9 W·h/kg energy density when the power density is 800 W/kg. After 2 000 charge and discharge cycles, the specific capacitance retention rate is 89%.
