摘要： PROBLEM TO BE SOLVED: To provide a battery with high capacity and superior cycle characteristic by suppressing the deposition of lithium to a negative electrode in the charge of a nonaqueous electrolyte lithium secondary battery, having a positive electrode containing a positive active material capable of releasing/absorbing lithium ions in charge/discharge and a negative electrode containing carbon capable of absorbing/releasing lithium ions in charging/discharging. SOLUTION: Carbon fluoride is added to the negative electrode of a battery. Thereby, lithium ions equivalent to the irreversible capacity of a positive electrode in a first cycle charge react with the additive having large reaction amount per volume with the ions and are fixed to the negative electrode. As a result, the increase in volume of the negative electrode is suppressed, and in addition, the conductivity of the negative electrode is increased by carbon produced in the reaction. A battery design capable of ensuring sufficient filling amount of an active material and suppressing the deposition of lithium to the negative electrode in charge is made possible, and the battery with high capacity and superior cycle characteristics can be obtained.
