Abstract

Nanostructure engineering and carbon incorporation can effectively achieve superior lithium storage performance of SiO₂ anode. However, the working operation at high rates and extreme temperatures remains a challenge for SiO₂-based anode. Here, SiO₂@N-doped carbon (SiO₂@NC) nanospheres encapsulated in the TiN/C nanofibers (SiO₂@NC@TiN/C) were fabricated via coaxial electrospinning. The SiO₂@NC@TiN/C with a robust structure and conductive shells exhibited excellent cycling stability and fast Li⁺ diffusion kinetics. The SiO₂@NC@TiN/C electrode delivered a superior rate performance (317.9 mAh g⁻¹) and ultra-long cycle life (284.5 mAh g⁻¹ after 3200 cycles) at 10 A g⁻¹. Furthermore, the SiO₂@NC@TiN/C electrode maintained an excellent cycling stability at 65 ℃ (420.6 mAh g⁻¹ after 300 cycles at 1 A g⁻¹). This research offered an ingenious design way to create a multilayer coated anode, which could exhibit good electrochemical performance under harsh conditions.

期刊介绍： The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
