摘      要：p-Benzoquinone(BQ)is a promising candidate for next-generation sodium-ion batteries(SIBs)because of its high theoretical specific capacity,good reaction reversibility,and high resource ***,practical application of BQ faces many challenges,such as a low discharge plateau(~2.7 V)as cathode material or a high discharge plateau as anode material compared with inorganic materials for SIBs and high solubility in organic electrolytes,resulting in low power and energy ***,tetrahydroxybenzoquinone tetrasodium salt(Na_(4)C_(6)O_(6))is synthesized through a simple neutralization reaction at low *** four-ONa electron-donating groups introduced on the structure of BQ greatly lower the discharge plateau by over 1.4 V from ~2.70 V to ~1.26 V,which can change BQ from cathode to anode material for *** the same time,the addition of four-ONa hydrophilic groups inhibits the dissolution of BQ in the organic electrolyte to a certain *** a result,Na_(4)C_(6)O_(6) as the anode displays a moderate discharge capacity and cycling performance at an average work voltage of ~1.26 V versus Na/Na^(+).When evaluated as a Na-ion full cell(NIFC),a Na_(3)V_(2)(PO_(4))_(3)||Na_(4)C_(6)O_(6) NIFC reveals a moderate discharge capacity and an average discharge plateau of ~1.4 *** research offers a new molecular structure design strategy for reducing the discharge plateau and simultaneously restraining the dissolution of organic electrode materials.
