Laser Synthesis of Hard Carbon for Anodes in Na‐Ion Battery

Advanced hard carbon is produced by short-time laser irradiation, which increases the local ordered structure to give a high proportion of Na storage capacity in low voltage plateau. It could bring a 11% increase in energy density when matching with Na3V2(PO4)2F3 cathode to make a full cell.
