摘要 以杏壳活性炭为原料,KOH为活化剂,制备了活性炭样品,并以1 mol/L LiClO4/PC溶液作电解液,组装成模拟电容器,进行电化学性能测试。活性炭的比电容随碱用量的增加而增高,最高达到161 F/g。比电容随比表面积的增加而升高,比表面积高于2 000 m2/g后,增加程度逐渐变小。 Activated carbon samples were prepared with amygdaline shell activated carbon as raw material and KOH as activator.The supereapacitor with the activated carbon samples in 1 mol/L LiClO4/PC electrolyte was assembled and the electrochemical performance was tested. The specific capacity was raised with increasing of alkali dosages and the maximum was 161 F/g, The specific capacitance was increased with increasing of the specific surface area and its increment decreased when the specific surface area was above 2 000 m^2/g.
