Titanium nitride coating to enhance the performance of silicon nanoparticles as a lithium-ion battery anode

Titanium nitride (TiN) coated silicon nanoparticles were synthesized via reduction of TiO2-coated silicon nanoparticles under nitrogen. When evaluated as an anode for lithium-ion batteries, the material exhibited stable performance and excellent coulombic efficiency for 100 charge-discharge cycles at 0.1 C rate, in addition to significantly enhanced rate performance.
