Enhancing Performance of the Ti(III)/Ti(IV) Couple for Redox Battery Applications

Abstract

The effect of using chelating and reducing agents in the anolyte on the performance of Fe-Ti redox battery system was investigated. The discharge performances of batteries having MeCOCH2COMe [123-54-6] or oxalic acid [144-62-7] in the electrolyte were unchanged or inferior when compared to the std. Fe-Ti battery. In studies with reducing agents Pb was stable in the electrolyte, but some reaction occurred at Sn surface. For Fe-Ti batteries with 3.0N HCl in catholyte and 3.5N HCl in anolyte, the resp. open-circuit potentials with no reducing agent, Pb, and Sn were 0.782, 1.193, and 1.17 V. [on SciFinder(R)]
