Abstract
The prevent invention provides a non-aqueous electrolyte for batteries comprising the dissolving of an electrolytic salt in an organic solvent, wherein said organic solvent contains at least one type each of cyclic carbonate compound, alkyl mono-carbonate compound represented by chemical formula (1), alkylene bis-carbonate compound represented by chemical formula (2), glycol diether compound represented by chemical formula (3) (R.sup.6 O--(R.sup.7 O).sub.n --R.sup.8) and phosphorous-containing organic compound. The use of at least one type of glycol diether represented with this general formula is able to yield satisfactory output characteristics by lowering the internal resistance of the battery as a result of increasing the mobility of lithium ions at the solid-liquid interface.
