Scientists are taking a variety
Scientists are taking a variety of approaches to battling the growth of spiky, dangerous lithium dendrites in a new generation of powerful batteries. ↓↓More info and references below↓↓
Lithium-ion batteries have revolutionized the way we power our gadgets, and they even nabbed the Nobel Prize in Chemistry this year. But scientists want to make even more powerful versions. Replacing the graphite anodes in Li-ion batteries with lithium metal ones could double the batteries’ charge capacity. But dendrites—spiky lithium structures that can accumulate on the anode during charging—can short circuit batteries, posing a serious safety hazard. So scientists are working to master the dendrite problem by investigating how the structures grow and developing solutions to suppress them, such as building physical barriers or solid electrolytes to halt their growth. Watch this video to learn more.
