Non-Layered Ti2n Synthesized By Plasma Process For The Anodes Of Lithium-Ion Batteries

Non-layered epsilon-Ti2N with a work function of similar to 4.75 eV, synthesized by a rapid process assisted by N-2 plasma immersion, is successfully applied as the anode material of lithium-ion batteries with good performance; it exhibits discharge capacity of similar to 450 mA h g(-1), which is close to the theoretical value, coulombic efficiencies of > 85%, and capacity retentions (>= 80%).
