Universal Bulk Pre‐Oxidation Strategy for Programming High‐Performance Pitch‐Derived Hard Carbon Anodes

) in conventional carbonate electrolytes, surpassing most reported pitch-derived analogues. Through in situ characterization analyses, a sequential "adsorption-intercalation-pore filling" sodium storage mechanism, facilitated by the tailored disorder-pore architecture, is elucidated. This work provides a universal platform for achieving uniform bulk pre-oxidation of carbon precursors, offering fundamental insights and scalable material design principles for high-performance sodium-ion batteries.
