一种对称型水系钠离子电池
摘要：
本发明设计电化学储能领域，具体涉及一种对称型水系钠离子电池，所述电池的正极电极材料层与负极电极材料层所使用的电极材料均为NaxMnO2(x＝0.22-0.66)，所述电池的电解液为钠盐的水溶液，所述电解液中钠离子浓度为0.5-6mol·L-1。本发明通过选用NaxMnO2作为电极材料，并将电解液中的钠离子浓度设置为0.5-6mol·L-1，从而使得本发明设置的对称型水系钠离子电池具有较高的能量密度，能达到40Wh/kg以上。
摘要（英）：

The invention relates to the field of electrochemical energy storage, in particular to a symmetrical aqueous sodium ion battery. The electrode material used in a positive electrode material layer anda negative electrode material layer of the battery is NaMnO2, wherein x is equal to 0.22-0.66. The electrolyte of the battery is aqueous solution of sodium salt, and the concentration of sodium ions in the electrolyte is 0.5-6mol.L<-1>. By selecting NaMnO2 as the electrode material and setting the concentration of sodium ions in the electrolyte to be 0.5-6mol.L<-1>, the symmetrical aqueous sodium ion battery of the invention has higher energy density which can reach more than 40Wh/kg.
