“…In the CVD process, reactions are conducted in a quartz tube with the favor of carrier gas in higher temperatures (200-1100 • C) [63][64][65]. Whereas, the ultrahigh temperature (>2000 • C) is adopted for the growth of certain materials [66]. Notably, a wide range of materials can be synthesized with various morphology.…”

Recent progress in the fabrication of controlled structures and advanced materials has improved battery performance in terms of specific capacity, rate capability, and cycling stability. However, interfacial problems such as increased resistance and contact instability between the electrodes and solid/liquid electrolytes still put pressure on the controllable formation of structures and the improvement of performance as well as safety. Here, we first briefly introduce the deposition techniques in terms of working mechanism and experimental process, then illustrate the associated advantages/disadvantages of the surface engineering methods based on deposition techniques (physical vapor deposition and chemical reaction deposition) to the provision of reference for researchers selecting the appropriate approach. Second, we exemplify the Si/LiCoO2/LiPON/Li to demonstrate the main progress made in lithium-ion batteries, elaborating on the efforts in engineering the reactive surface utilizing the deposition techniques. Finally, general conclusions and prospects for future advanced thin film deposition techniques in the field of lithium-ion batteries are presented.

“… 7 PyG preparation conditions, such as temperature and pressure of CVD pyrolysis, flow rates of carbon source gas and substrate selection, have a significant impact on the microstructure and properties of PyG, thus the preparation of high-quality anisotropic pyrolytic graphite and the study of microscopic kinetic processes have always been the focus of attention. Hareesh et al 8 prepared PyG coatings by CVD method and investigated the effect of pyrolysis temperature on the microstructure, density, oxidation kinetics, and growth and nucleation modes of the deposited PyG. It was found that the PyG growth rate was proportional to the pyrolysis temperature, the disorder of stacking was inversely proportional to the pyrolysis temperature, and the increase of temperature favors for the graphitization of PyG.…”
