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.

通过MoS2涂层改善贫电解质条件下的锂金属电池性能

尽管锂金属电池（LMB）提供了最高的能量密度之一，但锂枝晶生长问题以及锂与电解质之间的化学反应性限制了它们的应用。为了在贫电解液，薄锂金属和高质量负载的实际条件下实现稳定的LMB，我们在锂金属阳极上引入了有效的MoS ₂保护涂层，并分析了其在实际条件下的电化学性能。MoS ₂涂层通过防止树枝状晶体生长和电解质变干，成功地稳定了锂金属表面的化学活性，从而在严格的条件下将锂金属电池的循环寿命提高了三倍。
