🔋 Pore‐Stitching Engineering of Biomass‐Derived Hard Carbon for Enhanced Sodium‐Ion Storage

📝 استراتژی دوخت منافذ با هیدروکسی‌اتیل سلولز برای بازسازی کربن سخت مشتق از زیست‌توده، ظرفیت ۳۷۵.۳ mAh g−۱ و پایداری ۹۷.۸٪ پس از ۲۰۰ چرخه در باتری یون سدیم را نشان می‌دهد.

💡 Novelty & Significance:
The novelty lies in using hydroxyethyl cellulose to "stitch" pores in acid/alkali-purified biomass hard carbon, reconstructing the disrupted framework and reducing irreversible capacity loss. This yields 375.3 mAh g⁻¹ and a 150 Wh kg⁻¹ pouch cell with 97.8% retention after 200 cycles, offering a viable route to convert impurity-rich agricultural waste into practical sodium-ion battery anodes.
