摘　　要：在简要介绍纳米颗粒的基本物理-化学性能及其制备现状的基础上,着重论述了纳米颗粒自组装的类型及原理,总结了纳米颗粒自组装在锂离子电池上的应用研究进展,并指出该应用中存在制备效率低、污染较大等问题,提出今后工作将集中在开发合适组装单元、揭示自组装基本原理、简化制备程序等方面,认为纳米材料合成过程中实现多层次/功能电池结构调控是未来发展的重要方向之一。The physical/chemical properties and synthesis methods of nanoparticles were briefly introduced, and then the type and principle of the self-assembly of nanoparticles were discussed in detail. The research progress in the application of the nanoparticle self-assembly in lithium-ion batteries was summarized, and the existing problems such as the low production efficiency and high pollution in this field were also pointed out. The future works will be focused on developing approp-riate building blocks, disclosing the self-organization mechanisms and simplifying the fabrication processes, and the simultaneous yet effective adjustion of the self-assembly processes in the materials synthesis stage for advanced battery components with hierarchical structures or functions is one of the most important approaches.
