Abstract:The study presents a hybrid hard-carbon/nanocrystalline-Bi2S3 material applicable for negative electrodes in sodium-ion batteries. Through a series of comprehensive analyzes, including electrochemical measurements, operando XRD, ex-situ solid-state NMR, and high-resolution...
This study introduces a core–shell C@SnxSy@HCS composite anode for sodium-ion batteries, achieving low discharge voltage (0.5 V), high initial Coulombic efficiency (73.56%), excellent rate capability, and outstanding cycling stability.
Hard carbons are promising negative electrode materials for Na-ion batteries (SIBs), and the process of (de)insertion of Na+ ions into/from hard carbons has attracted much attention in recent research. Because...
