Role of Structural Hydroxyl Groups in Enhancing Performance of Electrochemically-Synthesized Bilayer V2O5
Structural OH species, an intrinsic feature of electrochemically-synthesized V2O5 (EC-V2O5), are highly thermally and electrochemically stable and are responsible for the improved cycle life and reversible capacity of these materials for beyond-lithium-ion systems. Read More

Water as a Catalyst – Improving how Batteries Function
Anyone who has ever dropped a cell phone in the sink will tell you that electrical devices and water do not go together. However, a new study has shown that conventional wisdom may not hold on the molecular scale in some beyond-lithium-ion batteries. Read More

Trace Water Catalyzes Lithium Peroxide Electrochemistry
Water at ppm levels catalyzes the conversion of lithium superoxide (LiO2) to lithium peroxide (Li2O2) by the reaction cycle shown. Because water is not consumed in the cycle, trace amounts leverage large effects. Read More

Untapped Potential: The Need and Opportunity for High-Voltage Aqueous Redox Flow Batteries
Prior studies of the techno-economic design space for aqueous redox flow batteries (AqRFBs) have almost exclusively focused on cell potentials ≤1.5 V, due, at least in part, to the belief that battery operation at higher cell potentials in not feasible due to electrolyte decomposition. However, … Read More
