What is Enhancing Electrochemical Performances of Small Quinone Toward Lithium and Sodium Energy Storage about?
Further application of organic quinone cathodes is restricted because they are inherent in poor conductivity and tend to dissolve in aprotic electrolytes. Salinization can work on the strong solubility of quinones. Herein, the ortho-disodium salt of tetrahydroxyquinone (o-Na 2 THBQ) was selected to promote the electrochemical properties of tetrahydroxyquinone (THBQ). Reduced dissolution of o-Na 2 THBQ in electrolyte after salinization (replacement of two H with two Na) contributed to enhanced electrochemical performance. In sodium-ion batteries (SIBs) in ester-based electrolyte, o-Na 2 THBQ cathodes at 50 mAÁg -1 exhibited a reversible discharge capacity of 107 mAhÁg -1 after 200 cycles. Ulteriorly, in ether-based electrolyte, reversible discharge capacities of 200.4, 102.2, 99.5 and 88 mAhÁg -1 were obtained at 800, 1600, 3200 and 4800 mAÁg -1 after 1000, 2000, 5000 and 8000 cycles, respectively. The ultraviolet absorption spectra and ex situ dissolution experiments of THBQ and o-Na 2 THBQ showed that o-Na 2 THBQ hardly dissolved in ether-based electrolyte. In lithium-ion batteries (LIBs), graphene was selected to further enhance the conductivity of o-Na 2 THBQ. At 50 mAÁg -1 , o-
