Sodium Batteries Take a Leap Towards the Grid

Lithium-ion batteries may dominate today’s clean energy storage, but they come with problems: they rely on scarce lithium and cobalt, and their costs are tied to volatile supply chains. That is why researchers have long looked to sodium — far more abundant and geographically widespread — as a promising alternative. Until now, however, sodium metal … Continue reading Sodium Batteries Take a Leap Towards the Grid

Solar Cells and Batteries Become One: A Leap for Portable Power

For a long time, solar cells and batteries have worked as partners, as separate devices. One captures light, the other stores the electricity. Now, researchers have blurred that boundary with a breakthrough that could reshape how we power portable electronics. A new study presents a highly efficient all-perovskite solar-battery system; a device that doesn’t just … Continue reading Solar Cells and Batteries Become One: A Leap for Portable Power
