Enhanced electrochemical performance of FeS coated by Ag as anode for lithium-ion batteries

▸ The FeS and FeS/Ag composite are successfully prepared with a facile electroless deposition method. ▸ The improved cycling stability is ascribed to the suppression of the volume expansion after Ag coating. ▸ The improved rate ability is ascribed to the enhanced electronic conductivity of Li2S after Ag coating.
