    • Nonaqueous electrolytes which can produce a battery of high capacity and excellent storability and cycle characteristics are provided, as are batteries produced with the electrolytes. The electrolytes include ones with (i) an aromatic compound having 7-18 carbon atoms in total and a fluorinated cyclic carbonate having two or more fluorine atoms, (ii) diethyl carbonate and a fluorinated cyclic carbonate having two or more fluorine atoms, (iii) at least one of a cyclic sulfonic acid ester compound, disulfonic acid ester compound, nitrile compound, and a compound of formula (1) and a fluorinated cyclic carbonate having two or more fluorine atoms, or (iv) a nonaqueous electrolyte solution for use in a high-voltage battery having a final charge voltage of 4.3 V or higher and having a fluorinated cyclic carbonate with two or more fluorine atoms.
    • 提供了可以生产高容量电池和优异的储存性和循环特性的非水电解质,电解质产生的电池也是如此。 电解质包括(i)总共具有7-18个碳原子的芳族化合物和具有两个或更多个氟原子的氟化环状碳酸酯,(ii)碳酸二乙酯和具有两个或更多个氟原子的氟化环状碳酸酯的(i) )环状磺酸酯化合物,二磺酸酯化合物,腈化合物和式(1)化合物中的至少一种和具有两个或更多个氟原子的氟化环状碳酸酯,或(iv)使用的非水电解质溶液 在具有4.3V或更高的最终充电电压的高压电池中,并具有具有两个或更多个氟原子的氟化环状碳酸酯。
