摘要 超级电容器低温性能的好坏与其电极材料及电解液密切相关,通过电化学测试研究了以活性炭和石墨烯为电极材料,1mol·L^(-1)不同体积含量丙酸甲酯(MP)的SBP-BF_(4)/(PC+DMC+MP)体系为电解液的超级电容不同温度时的电化学性能,分析发现,MP有助于提升有机电解液的低温性能,MP溶剂体积分数为33%的活性炭超级电容可在-55℃正常工作,比电容为31.79F·g^(-1)。 The low temperature performance of supercapacitor is closely related to its electrode materials and electrolyte.Researched the electrochemical performance of supercapacitor at different temperatures using activated carbon or graphene as electrode materials and 1mol·L^(-1) SBP-BF_(4)/(PC+DMC+MP)system with different volume content of methyl propionate(MP)is electrolyte through electrochemical testing.The analysis found that MP helps to improve the low temperature performance of organic electrolytes and the activated carbon supercapacitors with MP solvent volume fraction of 33%can work normally at-55℃,and the specific capacitance is 31.79F·g^(-1).
