Lithium-ion batteries (LIBs) are very promising power supply systems for a variety of applications, such as electric vehicles, plug-in hybrid electric vehicles, grid energy storage, and microelectronics. However, to realize these practical applications, many challenges need to be addressed in LIBs, such as power and energy density, cycling lifetime, safety, and cost. Atomic layer deposition (ALD) is emerging as a powerful technique for solving these problems due to its exclusive advantages over other film deposition counterparts. In this review, we summarize the state-of-the-art progresses of employing ALD to design novel nanostructured electrode materials and solid-state electrolytes and to tailor electrode/electrolyte interface by surface coatings in order to prevent unfavorable side reactions and achieve optimal performance of the electrode. Insights into the future research and development of the ALD technique for LIB applications are also discussed. We expect that this review article will provide resourceful information to researchers in both fields of LIBs and ALD and also will stimulate more insightful studies of using ALD for the development of next-generation LIBs.
锂离子电池（LIBs）对于各种应用来说都是非常有前景的电源系统，例如电动汽车、插电式混合动力汽车、电网储能和微电子设备。然而，为了实现这些实际应用，锂离子电池需要解决许多挑战，如功率和能量密度、循环寿命、安全性和成本。原子层沉积（ALD）作为一种强大的技术正在兴起，因为它相对于其他薄膜沉积方法具有独特的优势。在这篇综述中，我们总结了利用原子层沉积来设计新型纳米结构电极材料和固态电解质，以及通过表面涂层来定制电极/电解质界面以防止不利的副反应并实现电极最佳性能的最新进展。还讨论了对用于锂离子电池应用的原子层沉积技术未来研发的见解。我们期望这篇综述文章能为锂离子电池和原子层沉积这两个领域的研究人员提供丰富的信息，也将激发更多关于利用原子层沉积来开发下一代锂离子电池的有见地的研究。
