The article discusses the development of indium nitride (InN) nanowires as a new anode material for lithium-ion batteries (LIBs). InN, with its low redox potential (<0.7 V vs Li/Li⁺) and narrow bandgap (0.69 eV), is proposed as a high-energy density anode material. The nanowires are grown on Au-decorated carbon fibers (InN/Au-CFs) using chemical vapor deposition, achieving a high aspect ratio of 400. The Au-CFs provide high conductivity and enhance the binding force for dense growth of InN nanowires, leading to shortened Li-ion diffusion paths, high structural stability, and fast Li⁺ kinetics. The InN/Au-CFs anode exhibits stable and high-rate Li delithiation/lithiation without Li deposition, achieving a capacity of 635.5 mAh g⁻¹ at 0.1 A g⁻¹ after 450 cycles and 416 mAh g⁻¹ at a high rate of 30 A g⁻¹. The full cells paired with commercial LiNi₀.₈Co₀.₁₅Zn₀.₀₅O₂ cathode show long-term cycling stability, demonstrating the potential of InN nanowires as a promising material for high-energy-density and high-power-density LIBs.The article discusses the development of indium nitride (InN) nanowires as a new anode material for lithium-ion batteries (LIBs).
