NOVELTY - The battery (10) has a battery main body provided with a negative electrode (A), a positive electrode (C) and a non-aqueous electrolyte. The non-aqueous electrolyte contains aromatic ketone compound, butyrolactone, ethylene carbonate, dimethyl carbonate, diethyl carbonate and methyl ethyl carbonate. The negative electrode is provided with a negative electrode active material. Electric potential of the negative electrode is more than 0.4V. An electron withdrawing group and/or aromatic group is bonded with a condensed aromatic ring through a single bond or coupling group.    USE - Electrolyte solution containing non-aqueous secondary battery i.e. lithium ion secondary battery, for use in a portable electronic device. Uses include but are not limited to a notebook personal computer, a pen input personal computer, a mobile personal computer, an electronic book player, a mobile telephone, a cordless phone mobile unit, a pager, a hand-held terminal, a portable fax machine, a portable copy, a portable printer, a headphone stereo, an LCD TV, a handicap cleaner, a portable CD, a mini-disk, an electric shaver, a transceiver, an electronic organizer, a calculator, a memory card, a portable tape recorder, a radio and a backup power supply. Can also be used for a motor vehicle such as electric vehicle and hybrid vehicle, a lighting fixture, a toy, a game machine device, a load conditioner, a timepiece, an electronic flash, a camera and a medical device such as pacemaker, hearing aid and shoulder massager.    ADVANTAGE - The electric potential of the negative electrode is more than 0.4V so as to ensure high-rate discharge capacity maintenance property and low-temperature characteristic.    DETAILED DESCRIPTION - The negative electrode active material is selected from one among lithium alloy, metal oxide and lithium titanic acid. The condensed aromatic ring is a polycyclic aromatic ring or fused aromatic ring.
