摘要

本研究顺应了硅碳阳极发展的趋势，合成了商业化化学气相沉积硅碳（CVD Si/C）阳极材料，并创新地将桃胶多糖（PG）与聚丙烯酸（PAA）和单壁碳纳米管（SWCNTs）结合在一起，制备了具有优异长期循环稳定性的Si/C@PGS电极。通过全面的材料表征和密度泛函理论（DFT）计算，阐明了电极循环稳定性增强的机制。电化学测试表明，在0.1 C条件下，Si/C@PGS电极在200次循环后仍能保持88.4%的高容量保持率。该电极也成功集成到商用袋式电池中，在1c充电和2c放电条件下可实现超过1600次的稳定循环。这项研究为高能量密度锂离子电池的实际应用提供了一个潜在的解决方案。

Gradient Hydrogen Bonding-Reinforced Peach Gum/Polyacrylic Acid Binder Enables Commercialization Breakthrough for Chemical Vapor Deposition Silicon-Carbon Anodes

This study aligns with the trend in silicon-carbon anode development by synthesizing commercial chemical vapor deposition silicon-carbon (CVD Si/C) anode materials and innovatively incorporating peach gum polysaccharide (PG) with polyacrylic acid (PAA) and single-walled carbon nanotubes (SWCNTs) to fabricate Si/C@PGS electrodes with superior long-term cycling stability. Through comprehensive material characterization and density functional theory (DFT) calculations, the mechanisms underlying the enhanced cycling stability of the electrodes are elucidated. Electrochemical tests demonstrate that Si/C@PGS electrodes maintain a high-capacity retention rate of 88.4% after 200 cycles at 0.1 C. The electrodes were also successfully integrated into commercial pouch cells, achieving stable cycling for over 1600 cycles under 1 C charge and 2 C discharge conditions. This research offers a potential solution for the practical application of high-energy-density lithium-ion batteries.
