Fe 3 SnC@CNF: A 3 D Antiperovskite Intermetallic Carbide System as a New Robust High‐Capacity Lithium‐Ion Battery Anode (original) (raw)

Fe3SnC@CNF, a 3D antiperovskite intermetallic carbide, is introduced as a high-capacity anode material for lithium-ion batteries. The composite exhibits a reversible lithium-ion capacity of 600 mAh g−1 after electrospinning and pyrolysis, with remarkable cycling stability (96% capacity retention after 1000 cycles) and impressive rate performance (500 mAh g−1 at 2 A g−1). This study highlights the potential of carbide-based materials in improving lithium-ion battery technology, addressing limitations seen in conventional anode materials.
