Abstract
Abstract Emerging sodium‐ion batteries (NIBs) and potassium‐ion batteries (KIBs) show promise in complementing lithium‐ion battery (LIB) technology and diversifying the battery market. Hard carbon is a potential anode candidate for LIBs, NIBs, and KIBs due to its high capacity, sustainability, wide availability, and stable physicochemical properties. Herein, a series of hard carbons is synthesized by hydrothermal carbonization and subsequent pyrolysis at different temperatures to finely tune their structural properties. When tested as anodes, the hard carbons exhibit differing ion‐storage trends for Li, Na, and K, with NIBs achieving the highest reversible capacity. Extensive materials and electrochemical…
