Crystallographic Shear-Phase Transition Metal Oxides for Fast-charging Batteries

Abstract

The goal of this research is to understand the correlations between structural stability, electronic structure, and ion insertion kinetics in oxide electrodes to enable insertion-type batteries with high power and high energy. To accomplish this goal, the objectives of this research are to (1) Synthesize and characterize CS-phase transition metal oxides of tungsten and niobium, (2) Perform electrochemical characterization of their ion-insertion behavior for protons (aqueous electrolyte) as well as cations (non-aqueous electrolytes), and (3) Characterize their optical and electronic structure changes during ion insertion. The outcome of this research will be correlating structure-electronic and structure-electrochemical properties in CS-phase transition metal oxide electrodes, the results of which will guide advances in the design of materials for high-power and high-energy batteries.Approved for Public Release
