Solid-state batteries (SSBs) have attracted increasing attention as one of the most promising next-generation batteries. However, various challenges remain for SSBs toward practical applications. Particularly, the interfacial issues between solid-state electrolyte (SSEs) and electrodes are critical factors affecting the performances of SSBs. Atomic and molecular layer deposition (ALD and MLD) are considered as ideal strategies for overcoming the interfacial issues facing SSBs. In the past years, promising progress has been reported using ALD/MLD to overcome the interfacial drawbacks in SSBs. In this Review, we summarize the recent progress of ALD/MLD techniques in the application of Li batteries, with a special focus on current progress in the shift from liquid to solid cells. Different sections, including the fabrication of interfacial materials, interfacial engineering on SSEs and electrodes, and thin-film/3D SSBs, are discussed in detail. Moreover, the future directions and perspectives of ALD/MLD in interface engineering for SSBs are disclosed.

作为最有前途的下一代电池之一，固态电池（SSB）引起了越来越多的关注。但是，SSB在实际应用中仍然面临各种挑战。特别地，固态电解质（SSE）和电极之间的界面问题是影响SSB性能的关键因素。原子和分子层沉积（ALD和MLD）被认为是解决SSB所面临的界面问题的理想策略。在过去的几年中，已经报道了使用ALD / MLD克服SSB的界面缺陷的令人鼓舞的进展。在这篇综述中，我们总结了ALD / MLD技术在锂电池应用中的最新进展，特别关注了从液态电池向固态电池转变的最新进展。不同的部分，包括界面材料的制造，详细讨论了SSE和电极以及薄膜/ 3D SSB的界面工程。此外，公开了针对SSB的接口工程中的ALD / MLD的未来方向和前景。
