Abstract
Although lithium-metal-based batteries (LMBs) offer one of the highest energy densities, the issues with Li dendrite growths and the chemical reactivity between Li and electrolytes limit their applications. To enable a stable LMB under the practical conditions of lean electrolyte, thin Li metal and high mass loading, we introduce an efficient protective coating of MoS2 onto the Li-metal anode and analyzed its electrochemical performance under practical condition. The MoS2 coating successfully stabilizes the chemical activity of Li-metal surface by preventing dendrite growth and electrolyte dry-out, which results in the enhanced Li-metal battery cycle life by three-fold under the stringent conditions.
