This perspective article reviews the research and advancements in lignocellulose-derived hard carbon anodes (HCAs) for sodium-ion batteries (SIBs). Lignocellulose, a low-cost and abundant resource, is promising for HCA production due to its economic viability and environmental friendliness. The article highlights the importance of understanding the chemical, crystalline, and multi-dimensional structures of lignocellulose components (cellulose, hemicellulose, and lignin) in influencing HCA performance. Key factors such as closed pore volume, defect density, and interlayer spacing are discussed, emphasizing their impact on sodium-ion storage capabilities. The study also explores the challenges in producing HCA with tailored properties for SIBs, including the need for green chemistry and sustainable development principles. Experimental results from various calcination temperatures and characterization techniques (XRD, SAXS, and GCD) are presented to demonstrate the relationship between HCA structure and electrochemical performance. The article concludes with recommendations for future research, focusing on improving HCA cycling stability and commercialization readiness.This perspective article reviews the research and advancements in lignocellulose-derived hard carbon anodes (HCAs) for sodium-ion batteries (SIBs).
