NOVELTY - A nonaqueous electrolyte contains a heterocyclic-ring-containing alcohol derivative (I).    USE - Nonaqueous electrolyte is used in lithium secondary batteries (claimed). Uses include but are not limited to notebook personal computers, mobile telephones, headphone stereo cassette tape recorders, liquid-crystal televisions, electronic organizers, calculators, radios, backup power supplies, motors, motor vehicles, electric vehicles, motorbikes, electric motorcycles, bicycles, electric-power-assisted bicycles, lighting fixtures, game machines, timepieces, electric tools, and cameras.    ADVANTAGE - The nonaqueous electrolyte provides lithium secondary batteries having suppressed battery resistance, and excellent durability and storage characteristics even in high-temperature environment.    DETAILED DESCRIPTION - A nonaqueous electrolyte contains a heterocyclic-ring-containing alcohol derivative of formula (I).    R1=1-12C haloalkyl;    R2=H, 1-12C (halo)alkyl, or 6-14C aryl optionally substituted by halo or 1-6C alkyl;    R1+R2+C=3-7C fluorocycloalkyl;    R3=H, 1-12C alkyl, 2-12C alkenyl, 2-12C alkylcarbonyl, 2-12C alkoxycarbonyl, 3-12C dialkylaminocarbonyl, 1-12C alkylsulfonyl, 2-12C alkenylsulfonyl, phenylsulfonyl optionally substituted by halo or 1-6C alkyl, 2-12C dialkylphosphoryl, or -SiR4R5R6;    R4-R6=1-12C alkyl, 2-12C alkenyl, 1-12C alkoxy, or 6-14C aryl;    Q=optionally substituted 5-membered or 6-membered aromatic heterocyclic which may be condensed with benzene ring;and    m=1, 2 or 3.    INDEPENDENT CLAIMS are included for the following:    (1) additive containing compound (I); and    (2) lithium secondary battery consisting of a positive electrode (1), a negative electrode (2) containing metallic lithium, lithium-containing alloy, metal which can be alloyed with lithium, alloy which can be alloyed with lithium, oxide in which dope and dedope of lithium ion is possible, transition-metal nitride in which dope and dedope of lithium ion is possible, and/or carbon material in which dope and dedope of lithium ion is possible as active material, and the nonaqueous electrolyte.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a coin-type battery.    Positive electrode (1)    Negative electrode (2)    Separator (5)    Gasket (6)    Spacer board (7)
