Self-discharge（SD） of AC/AC（AC ? activated carbon） electrochemical capacitors in aqueous solutions of lithium sulfate（Li2SO4） and lithium sulfate t iodide salts（Li2SO4tKI or Li2SO4tLi I） was investigated at 24 1C and 40 1C after cell potential hold at values from 1 V to 1.6 V.At24 1C,the cells exhibit lower SD in Li2SO4tKI than in Li2SO4,owing to the redox activity of the 2I /I2 system which drives the positive AC electrode to operate in narrow potential range and display lower potential drop th...
