一類(lèi)陰離子自由基液態(tài)電極材料研究
[Abstract]:The alkali metal is dissolved in ether solvents containing aromatic compounds, and an electron of the alkali metal is transferred to the aromatic compounds to form an alkali metal ion and an anionic radical. A class of blue and black liquids with high electronic conductivity and ionic conductivity were obtained by dissolving in ether solvents at the same time. When alkali metal is sodium, aromatic compound is biphenyl, ether solvent is ethylene glycol dimethyl ether, its electronic conductivity and ionic conductivity are 8.4 脳 10 ~ (-3) S.cm ~ (-1) and 3.6 脳 10 ~ (-3) S. cm ~ (-1), respectively. The electrode potential is 0.09 V vs.Na/Na~, which is suitable for negative electrode material and has the advantages of low raw material and easy preparation. A new type of secondary battery was constructed by using the solution of benzoquinone and anthraquinone (AQ) as positive electrode. The results show that the battery with AQ solution as positive electrode has the advantage of long cycle life and low cost. The development of the anion free radical liquid negative electrode provides a new idea for the development of new energy storage battery.
