Lithium metal battery prototype boasts 3 times the capacity of lithium-ions

• newatlas.com by Lisa-Ann Lee

But current lithium-ion battery technology is nearing its limits and the search is on for a better lithium battery. But one thing stands in the way: dendrites. If a new technology by Rice University scientists lives up to its potential, it could solve this problem and enable lithium-metal batteries that can hold three times the energy of lithium-ion ones.

Dendrites are microscopic lithium fibers that form on the anodes during the charging process, spreading like a rash till they reach the other electrode and causing the battery to short circuit. As companies such as Samsung know only too well, this can cause the battery to catch fire or even explode.

"Lithium-ion batteries have changed the world, no doubt," says chemist James Tour, who led the study.
