Abstract

Stable Li Metal Batteries Ordered micro-grooves are prepared by femtosecond laser on Cu foil for lithium metal battery. The deposition of Li can be directed by the micro-grooves to form ordered and dense Li arrays. This idea for tuning lithium nucleation sites on current collector can significantly enlighten the future work for high-energy-density anode-free full cells. More details can be found in article number 2206000 by Jun Tan, Shuo Bai, Feng Li, and co-workers.
