| Abstract: | The supercapacitor using the activated carbon(AC) as the negative electrode,LiNi1/3Co1/3Mn1/3O2 as the positive electrode and 1 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-prepared supercacpacitors reach 11 Wh/kg and 5 278 W/kg respectively.With the capacity ratio of 4:1 of the positive electrode and the negative electrode.The capacity maintenance ratio of the supercapacitors keep at 92% after 2 200 cycles.The prepared supercapacitor has high probability of commercialization. |
