LiNi1/3Co1/3Mn1/3O2/AC混合超级电容器正负极容量配比研究OA北大核心CSCDCSTPCD
Study on different capacity ratio of the positive electrode and the negative electrode of LiNil/3CO1/3 Mnl/3O2/AC hybrid supercapacitor
采用1 mol/L的LiBF4/AN(CH3CN)为电解液,对LiNi1/3Co1/3Mn1/3O2/AC体系混合超级电容器进行了电化学性能对比研究.通过优化正负极的容量配比,分别评价了对应的超级电容器的充放电性能、倍率性能和循环寿命.结果表明,在正负极容量配比为4:1时,该体系超级电容器的比能量为11 Wh/kg、比功率为5 278W/kg,经2200次循环后容量保持率为92%,有望实现实用化.
The supercapaeitor using the activated carbon (AC) as the negative electrode, LiNi1/3Co1/3Mn1/3O2 as the positive electrode and I mol/L LiBF4/AN as the electrolyte respectively was studied. To optimize the capacity ratio of the positive electrode and the negative electrode, electrochemical performance of charge and discharge ability, various discharge rates and cycle life were investigated. The results show specific energy and specific power of as-prep…查看全部>>
