摘要
以活性炭(AC)为正极,Li4Ti5O12和活性炭(AC)的混合物为负极组装成混合电容器。对比了水性粘结剂和油系粘结剂对混合电容器的放电容量、循环性能和内阻的影响。结果表明当负极中Li4Ti5O12和AC比例为1.5:1时,混合电容器的比容量最高,为79.5F/g,且2000次循环寿命衰减率仅为6.83%,有望实现实用化。
We assembled the hybrid capacitor with activated carbon(AC) as anode and Li4Ti5O12 and AC as cathode. We compared the influence of water-kind binder and oil-kind binder on discharge capacity, cycle performance and resistance of the hybrid capacitor. The result showed the hybrid capacitor had the highest capacity(79.5 F/g) when the mass ratio between Li4Ti5O12 and AC in the cathode was 1.5:1,and its capacity retention collapsed only by 6.83% after 2000 cycling times. It is available for this kind of hybrid capacitor to realize practional utilization.
