INL, UCSD researchers find slow, low-energy charging of Li batteries creates glassy lithium; high-performance Li-metal batteries

Green Car Congress

The findings suggest strategies for fine-tuning recharging approaches to boost battery life and—intriguingly—for making glassy metals for other applications. Compared to crystalline Li, glassy Li outperforms in electrochemical reversibility, and it has a desired structure for high-energy rechargeable Li batteries.
