密封AA型双电层超电容的研制

Study on AA-type sealed electrochemical double-layer capacitor

以多孔活性碳为原料,以目前工业化较为成熟的MH/Ni电池制作流程,配以合适的制备工艺,制作出密封AA型双电层超电容,对电容器的充放电行为、内压特性、循环伏安及交流阻抗等进行了初步研究。结果表明:所得双电层超电容器具有较好的综合性能,电容器比能量和能量密度分别达到了1 13Wh/kg和2 24Wh/L。

The carbon-based electrochemical double-layer capacitor was prepared via the path of making Ni/MH batteries industrially. The charge/discharge behaviors,internal pressure property,cyclic voltammetry characteristics and EIS tests were carried out and the preliminary analysis were given based on the experimental data. The results showed a good comprehensive properties of the capacitor and its specific energy and energy density reached to 1.13?Wh/kg and 2.24?Wh/L respectively.
