| 英文摘要 | Tin (Sn)-based materials are one of most promising candidates for rechargeable (Li+ and Na+ ion) batteries because of their high theoretical capacities (993 mAh/g for Li4.4Sn and 847 mAh/g for Na15Sn4) and reasonable working potentials. However, Sn-based anodes suffer from huge volume changes during cycling that hinder the applications in commercialized rechargeable batteries. Unique particle engineering to fabricate Sn-core-carbon(shell) (Sn@C) particles has been shown to address or circumvent these problems. In this work, a distinct core-shell-structured Sn@C anode material has been successfully developed by using a one-step and template-free process (colloidal spray pyrolysis). A comprehensive analysis of chemical reaction kinetics of core-shell particles assists the product design to control the particle composition and structure by tuning the process variables, such as reaction temperature and cosolvent concentration. The unique Sn@C anode delivers a high capacity of 720 mAh/g after 300 cycles at 0.5C for lithium-ion batteries and a high capacity of >500 mAh/g at 0.2C for sodium-ion batteries. More importantly, this work advances the design of high-performance Sn@C composites for lithium/sodium-ion batteries in scalable process development, particle engineering, and material innovation. |
