High-performance Si anodes with a highly conductive and thermally stable titanium silicide coating layer

2013

We report a simple route for synthesizing titanium silicide-coated Si anodes via the silicothermic reduction process of TiO₂-coated Si. The titanium silicide enhances the electrical conductivity of Si nanoparticles and provides a highly stable solid electrolyte interface layer during the cycling, resulting in excellent electrochemical performances and significantly improved high thermal stability.
