Recent advances in two-dimensional (2D) materials have led to the renewed interest in intercalation as a powerful fabrication and processing tool. Intercalation is an effective method of modifying the interlayer interactions, doping 2D materials, modifying their electronic structure or even converting them into starkly different new structures or phases. Herein, we discuss different methods of intercalation and provide a comprehensive review of various roles and applications of intercalation in next‐generation energy storage, optoelectronics, thermoelectrics, catalysis, etc. The recent progress in intercalation effects on crystal structure and structural phase transitions, including the emergence of quantum phases are also reviewed.

二维（2D）材料的最新进展已引起人们对嵌入作为一种强大的制造和加工工具的兴趣。插层是修改层间相互作用，掺杂2D材料，修改其电子结构，甚至将其转换为截然不同的新结构或相的有效方法。本文中，我们讨论了不同的插层方法，并对插层在下一代储能，光电，热电，催化等方面的各种作用和应用进行了全面的综述。插层对晶体结构和结构相变的影响的最新进展包括还回顾了量子相的出现。
