Stanford University researchers created an aluminum-ion battery that uses an electrolyte material made of urea, the main component of urine (after water).
A battery made with urea, commonly found in fertilizers and mammal urine, could provide a low-cost way of storing energy produced through solar power or other forms of renewable energy for consumption during off hours.
A battery developed in Stanford Professor Hongjie Dai’s lab could provide low-cost storage for solar energy. (Image credit...
