Nanodiamonds could help prevent lithium-ion battery fires while also paving the way to pure lithium electrodes.
Lithium-based batteries are known to form dendrites, which can lead to a short circuit and potential fire. To help alleviate this danger, researchers turned to nanodiamonds, often used to slow dendrite growth. After producing the nanodiamonds using a low-cost method, they team combined the diamond with the electrolyte solution used in lithium-ion batteries. This caused the lithium ions to attach to the nanodiamonds in an orderly way, stopping dendrite growth completely.
According to study co-author Yury Gogotsi, “This is an important step towards improving safety and increasing probability of use of pure metal anodes—not only lithium, but also, zinc, sodium and others—in rechargeable batteries.”
