Structure Regulation of Hard Carbon with Enriched Semi‐Closed Ultramicropores for Enhanced Rapid Sodium Storage
Changsha University of Science and Technology · Shanghai University
Abstract
Abstract Regulating the microstructure of hard carbon (HC) anodes has emerged as a popular strategy to enhance the application potential of sodium‐ion batteries (SIBs). However, the low platform capacity and inferior rate property remain significant barriers to their further development. Herein, HC materials with abundant ultramicropores (0.3‐0.8 nm) are prepared employed epoxy resin and zinc acetate as precursors. Benefiting from the abundant hydroxyl and epoxy groups, the synergistic generation of simple aromatic free radicals and the precipitated ZnO promote the cross‐linking between precursor molecules during the first‐step pyrolysis, alter the twisting and folding of carbon layers during high‐temperature…
