An anode-free zinc battery that could someday store renewable energy

Renewable energy sources, such as wind and solar power, could help decrease the world’s reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers reporting in […]
