Summary:
UCLA researchers in the Department of Material Science and Engineering have developed electrodes for rechargeable batteries which resist dendrite growth.
Background:
Rechargeable batteries have attracted attention due to their wide array of applications and environmental benefits. Rechargeable metal-ion batteries, such as lithium-ion batteries, are used in a variety of devices such as smartphones and electric vehicles. However, metal-ion batteries suffer from dendrite growth caused by the accumulation of metallic microstructures, leading to the death of the metal and possible short circuits, which can lead to hazardous problems. Therefore, there is a need to develop a new electrode for metal-ion rechargeable batteries that will limit or eliminate dendrite growth.
Innovation:
UCLA researchers in the Department of Materials Science and Engineering have developed an electrode that significantly enhanced the cyclability of metal-ion batteries. The electrode was shown to reduce dendrite growth in various metal-ion batteries, resulting in increased stability and higher performance in rechargeable batteries.
