Abstract
A non-aqueous electrolyte secondary battery has a high initial capacity and excels in cycle characteristics and storage characteristics even when charged until the potential of the positive electrode active material exceeds as high as 4.3V versus lithium. The non-aqueous electrolyte of the secondary battery contains both 1,3-dioxane and a sulfonic acid ester compound.
