📄 Abstract（原文）
ABSTRACT The growing demand for sodium‐ion batteries (SIBs) in grid storage underscores the need for electrode materials that balance performance and cost, including sustainable and robust carbon sources. The equitable and abundant distribution of materials for SIBs, along with their superior low‐temperature performance, safety, and fast‐charging capability, further distinguishes them from lithium‐ion batteries (LIBs). Hard carbon (HC) is the state‐of‐the‐art anode for SIBs, but current commercial HC production is localized mostly to one region of the world, raising concerns about supply chain vulnerability, critical material dependency, and environmental aspects. Here, the first demonstration of humins, an abundant biorefinery byproduct, as a precursor for HC anodes for sodium‐ion storage is reported. Humins were carbonized at C, and the resulting materials were subjected to comprehensive materials and electrochemical characterization. Among the temperatures studied, humins‐derived hard carbon synthesized at C delivers an initial reversible capacity , with stable cycling performance up to 500 cycles and excellent rate capability, representing the optimal performance. This study establishes humins as a promising and low‐cost carbon source that provides a route to mitigate supply chain risks and valorizes an underutilized biorefinery waste stream for high‐performance SIB anodes.
