Non-aqueous electrolyte secondary cell with improved safety |
摘要 |
A non-aqueous electrolyte secondary cell is provided having enhanced safety against overcharge and reduced self-discharge. The non-aqueous electrolyte secondary cell includes: a positive electrode having a positive electrode active material; a negative electrode having a negative electrode active material; and a non-aqueous electrolyte containing a non-aqueous solvent and electrolytic salt. The non-aqueous solvent contains 20 to 80 volume % tertiary carboxylic acid ester represented by Formula 2 at 25° C. and 1 atm. The non-aqueous electrolyte contains a halogenated benzene compound. where R1 to R4 each denote a straight-chained or branched alkyl group having 4 or less carbon atoms and may be the same or different. |
