| الوصف: | Funding Information: The part of the work related to the arc-discharge plasma-chemical synthesis, structural and electrochemical analysis was supported by the RSF grant 20-79-00085 . The part of the work related to the calculation and numerical simulation of the gas-dynamic processes was supported by the state contract with IT SBRAS. Publisher Copyright: © 2021 ; It was found that the variation of a buffer gas pressure in the reactor chamber can control the structure of the synthesized materials during electric arc sputtering of composite Sn–C electrodes. The gas dynamic model calculated by the direct simulation Monte Carlo method shows that the buffer gas pressure affects the local parameters of tin and carbon vapor condensation. As a result, Core-shell Sn–SnO2 nanoparticles packed in a carbon matrix with various structural properties have been synthesized. It has been found that an increase in the buffer gas pressure leads both to an increase in the average size of the synthesized nanoparticles and to the formation of a more disordered structure of carbon. In turn, the tin and carbon structure affects the electrochemical characteristics of the synthesized Sn–C composite as anode materials for lithium-ion batteries. ; Peer reviewed |
