New low-cost battery could help store renewable energy
Wind and solar energy projects are growing at a respectable clip. But storing electric power for days when the air is still or when the sun goes down remains a challenge, largely due to cost. Now researchers are developing a new battery that could bring the price of storage to more affordable levels. They report their new battery that uses low-cost materials—sodium and magnesium—in ACS' journal Chemistry of Materials.
