(a) Discharge capacity and coulombic efficiency of a vacuum impregnated and a non-impregnated TiO2 electrode, as a function of specific current, when cycled in 1 mol dm− 3 AlCl3/1 mol dm− 3 KCl between 0.4 to − 1.0 V vs SCE. Corresponding charge-discharge curves of the impregnated TiO2 electrode cycled at 1.0, 10, 20, 30 and 40 A g− 1
