    摘要： The present invention aims to improve the fire resistance of an electrolytic solution used for a lithium-ion battery and improve the life characteristics of the lithium-ion battery. In the lithium ion battery of the present invention, specific amounts of ethylene carbonate and dimethyl carbonate are used for a non-aqueous electrolytic solution, and trimethyl phosphate is added thereto. Specifically, the non-aqueous electrolytic solution contains 60 vol % or more of ethylene carbonate (EC) and dimethyl carbonate (DMC). The volume ratio of DMC to the sum of EC and DMC is 0.3 to 0.6, and the non-aqueous electrolytic solution contains 3 to 5 wt % of trimethyl phosphate (TMP) with respect to the total weight of the non-aqueous electrolytic solution. Such a non-aqueous electrolytic solution has an effect of improving the self-fire extinguishing property, and thus improves the safety of the lithium-ion battery.

    摘要： Provided is a technique of achieving a longer-life lithium ion secondary battery. The lithium ion secondary battery includes a cathode including a cathode active material containing Mn, an anode including an anode active material containing graphite and non-aqueous electrolytic solution including electrolyte, and LiBF4 and LiPF6 are allowed to coexist in the non-aqueous electrolytic solution. Especially preferably LiPF6 is contained more than LiBF4 in the electrolytic solution. Preferably the electrolytic solution further includes iodide salt. As a result, an oxide of phosphor and boron is deposited on the cathode, thus preventing elution of Mn included in the cathode. The amount of these electrolytes is preferably in the decreasing order of phosphor, boron and then iodine.

    摘要： In a charging/discharging unit provided with: a lithium secondary battery, a voltage detecting sensor for detecting a voltage and a current detecting sensor; the charging/discharging control unit is further provided with a controller, and a discharging element for performing a constant voltage discharging operation of 3 V. A voltage, V0, of the battery when a discharging operation is terminated (t=0) is measured by the voltage detecting sensor. If V0≦3.6 V, within a rest time during which the battery is not charged/discharged until a next charging operation, a voltage, V1, of the battery when a time, t1, has elapsed is measured by the voltage detecting sensor. If this voltage charge is in a range of V1-V0≧0.2 V, then the constant voltage discharging operation of 3 V is carried out for a time duration longer than or equal to 1 hour.
