Manipulating Electrocatalytic Reaction and Ion Intercalation to Improve Aqueous Batteries

Working Paper

Abstract

We report that electrocatalytic water decomposition can be leveraged to enhance the performance of aqueous batteries. Using the NaxFe[Fe(CN)₆]ǁNaTi₂(PO₄)₃ aqueous battery as a platform, we demonstrate that electrocatalytic water oxidation can serve as an electrochemical activation approach to achieving higher full cell capacity.
