Electrochemical Characteristics of $LiMn_2O_4$+Activated Carbon Electrode for Supercapacitor

Supercapacitor용 $LiMn_2O_4$+Activated Carbon 전극의 전기화학적 특성

This research which it sees adds $LiMn_2O_4$ in the activated carbon electrode the test against the effect which it follows is. Test cells, which were $LiMn_2O_4$fabricated with active mass composite consisted of (100-X)% of MSP-20 and (X)% of $LiMn_2O_4$ (X=20,40,60,80,100), exhibits the better specific capacitance than those of the cells fabricated with single active mass that is MSP-20. The enhanced properties of composite active mass could be caused by capability of $LiMn_2O_4$ powders. But the resistance was increase by proportionate in $LiMn_2O_4$ addition and when mixture ratio of the activated carbon and the $LiMn_2O_4$ being similar, to be low rather to the after where had become the maximum it came.
