| Popis: | This work demonstrates a high-performance and durable silicon nanoparticle-based negative electrode in which conventional polymer binder and carbon black additive are replaced with lignin. The mixture of silicon nanoparticles and lignin, a low cost, renewable, and widely available biopolymer, was coated on a copper substrate using the conventional slurry mixing and coating method and subsequently heat-treated to form the composite electrode. The composite electrode showed excellent electrochemical performance with an initial discharge capacity of up to 3086 mAh g–1 and retaining 2378 mAh g–1 after 100 cycles at 1 A g–1. Even at a relatively high areal loading of ∼1 mg cm–2, an areal capacity of ∼2 mAh cm–2 was achieved. The composite electrode also displayed excellent rate capability and performance in a full-cell setup. Through synergistic analysis of X-ray photoelectron spectroscopy, Raman, and nanoindentation experiment results, we attribute the amazing properties of Si/lignin electrodes to the judicio... |
