Lithium metal anodes are highly promising for next‐generation rechargeable batteries. However, implication of lithium metal anodes is hampered by the unstable electrochemical behavior. Herein, the fabrication of hermetic coatings of hybrid silicate on lithium metal surface using a simple vapor deposition technique under the ambient condition is reported. Such coatings consist of a “hard” inorganic moiety that helps to suppress lithium dendrites and a “soft” organic moiety that enhances the toughness. Lithium metal batteries, including Li–LiFePO₄ and Li–S batteries, made with such coated anodes show significantly improved lifetime. This work provides a simple yet effective approach to stabilize lithium metal anodes for high‐performance lithium metal batteries.

用简单的气相沉积法制备锂金属阳极杂化硅酸盐涂层

锂金属负极非常适合下一代可充电电池。但是，不稳定的电化学行为阻碍了锂金属阳极的应用。本文中，报道了在环境条件下使用简单的气相沉积技术在锂金属表面上制备杂化硅酸盐的气密涂层的方法。这种涂层由有助于抑制锂枝晶的“硬”无机部分和增强韧性的“软”有机部分组成。用这种涂层阳极制成的锂金属电池（包括Li–LiFePO ₄和Li–S电池）的使用寿命显着提高。这项工作为稳定高性能锂金属电池的锂金属阳极提供了一种简单而有效的方法。
