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
