Double-buffer-phase embedded Si/TiSi2/Li2SiO3 nanocomposite lithium storage materials by phase-selective reaction of SiO with metal hydrides
Energy Storage Materials（2022）
Abstract
•Si/TiSi2/Li2SiO3 nanocomposite was prepared by phase-selective reaction of SiO with metal hydrides.•Si/TiSi2/Li2SiO3 nanocomposite outperformed pristine and prelithiated SiO for up to 500 cycles without a significant decrease in initial Coulombic efficiency.•Si/TiSi2/Li2SiO3 nanocomposite demonstrated improved thermal stability and rate capability compared to pristine and prelithiated SiO.
