摘要
采用干法和湿法两种成型工艺制备了超级电容器用活性炭电极,考察了成型工艺对电极性能的影响。结果表明:干法电极碳颗粒之间接触更为紧密,干法电极密度达0.65 g/cm^3,相对于湿法电极提高了10%;干法电极在容量、内阻、循环性能上都优于湿法电极;干法成型工艺不使用任何溶剂,绿色环保、节省成本,是一种具有重要研究意义和商业应用价值的电极成型工艺。
Activated carbon electrodes were prepared by dry and wet methods to study the influences of the fabrication technology on the properties of electrodes in ultracapacitors. The results show that dry electrode is more impact with the density up to 0.65 g/cm3, which is 10% higher than that of wet electrode. Dry electrode performs better in capacity, resistance and cycle life in comparison with wet electrode. Dry method electrode formation technology has fatal research significance and commercial application value for its solvent-less, environment friendly and cost saving.
