| Popis: | Non-aqueous flow batteries have attracted extensive attention due to the advantages of wide voltage window, high energy density and wide operating temperature and so on. Herein, tetramethylthiuram disulfide (TMTD) with high intrinsic capacity (223 mAh/g) and high solubility (∼1 mol/L in chloroform) is investigated as the positive active material of the non-aqueous Li/disulfide semi-solid flow battery. The electrochemical activity and reversibility are investigated by cyclic voltammetry and linear scan voltammetry. This Li/TMTD battery with a high cell voltage of 3.36 V achieves coulombic efficiency of 99%, voltage efficiency of 73% and energy efficiency of 72% at the current density of 5 mA/cm2 with active material concentration of 0.1 mol/L. Moreover, the Li/TMTD battery can operate for 100 cycles without obvious efficiency decay, indicating good stability. |
