Non-layered Ti2N synthesized by plasma process for the anodes of lithium-ion batteries

Abstract

Non-layered ε-Ti₂N with a work function of ∼4.75 eV, synthesized by a rapid process assisted by N₂ plasma immersion, is successfully applied as the anode material of lithium-ion batteries with good performance; it exhibits discharge capacity of ∼450 mA h g⁻¹, which is close to the theoretical value, coulombic efficiencies of >85%, and capacity retentions (≥80%).
