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

Intercalation of Ca into a Highly Defective Manganese Oxide at Room Temperature
Nanocrystals of layered MnOx containing a high concentration of atomic defects and lattice water are shown to have remarkable electrochemical activity towards Ca2+ , amounting to a capacity of ~130 mAh/g at room temperature. Multimodal characterization revealed the notable degree of intercalation by probing the … Read More
