This perspective reviews the synthesis strategies and challenges of lignocellulose-derived hard carbon anodes for sodium-ion batteries (SIBs). Hard carbon anodes, derived from lignocellulosic biomasses, offer a promising alternative due to their low cost, abundance, and environmental benefits. The study highlights the importance of optimizing the structure and performance of hard carbon anodes derived from cellulose, hemicellulose, and lignin. The synthesis methods and challenges in producing these materials for SIBs are discussed, emphasizing the need for controlling the microstructure and multi-dimensional characteristics of lignocellulose to enhance sodium-ion storage capabilities. The paper discusses the role of lignin, cellulose, and hemicellulose in the formation of hard carbon anodes, noting their different chemical structures and aggregate states. It also explores the effects of calcination temperatures on the properties of hard carbon anodes, including their crystallinity, pore structure, and electrochemical performance. The study compares the electrochemical performance of hard carbon anodes derived from cellulose (CHC), lignin (LHC), and hemicellulose (HCHC), finding that CHC and LHC exhibit higher capacities and better rate capabilities than HCHC. The paper also discusses the importance of pore engineering in improving the electrochemical performance of hard carbon anodes, emphasizing the need for precise control over pore size and volume to achieve high capacity and rate capabilities. The study highlights the potential of lignocellulose-derived hard carbon anodes for commercial SIBs, noting their stability and performance under various conditions. Finally, the paper emphasizes the need for sustainable and green chemical processes in the production of hard carbon anodes to meet the demands of commercial applications.This perspective reviews the synthesis strategies and challenges of lignocellulose-derived hard carbon anodes for sodium-ion batteries (SIBs).
