Boosting electronic and Li+ transport in silicon via titanium nitride incorporation for high-performance all-solid-state lithium-ion batteries

Abstract

Incorporating highly conductive TiN significantly improves the rate performance and cycling stability of Si anodes. Si@TiN anode based all-solid-state Li-ion batteries provide a specific capacity of 158.9 mAh g⁻¹ at 0.1C, retain 50.0 mAh g⁻¹ at a high rate of 40C, and exhibit stable cycling for 1000 cycles at 2C.
