NOVELTY - A nonaqueous electrolyte solution comprises a lithium salt and a nonaqueous solvent which dissolves the lithium salt. The nonaqueous electrolyte solution contains an alkyne-containing cyclic compound (I), and lithium complex oxide, a metal-containing oxalate compound (II), and/or carbonate having carbon-carbon unsaturated bond(s) or fluorine atoms (excluding compound (I)).    USE - Nonaqueous electrolyte solution is used for batteries (claimed). Uses include but are not limited to mobile telephones, notebook personal computers, electronic book players, portable copiers and printers, liquid-crystal televisions, transceivers, electronic organizers, calculators, memory cards, radio, backup power supply, motor vehicles, lighting fixtures, toys, timepiece, electric tools, and cameras.    ADVANTAGE - The nonaqueous electrolyte solution has excellent durability, cycle characteristics, storage property, and load properties.    DETAILED DESCRIPTION - A nonaqueous electrolyte solution comprises a lithium salt and a nonaqueous solvent which dissolves the lithium salt. The nonaqueous electrolyte solution contains an alkyne-containing cyclic compound of formula (I), and lithium complex oxide of formula: LiaXOn'Fm', a metal-containing oxalate compound of formula (II), and/or carbonate having carbon-carbon unsaturated bond(s) or fluorine atoms (excluding compound (I)).    X=element of group 13, 15 or 16 of period 2 or 3;    a=1-2;    n'=1-3;    m'=1-2;    X,Z=C(R1)2, C=O, C=N-R1, C=P-R1, O, S, N-R1, or P-R1;    Y'=C(R1)2, C=O, S=O, S(=O)2, P(=O)-R2, or P(=O)-OR3;    R,R1=H, halo, or 1-20C hydrocarbyl optionally having functional group;    R2=1-20C hydrocarbyl optionally having functional group;    R3=Li, NR4, or 1-20C hydrocarbyl optionally having functional group;    R4=1-20C hydrocarbyl optionally having functional group;    n,m=0 or more;    W'=R;    A=alkali metal;    M=transition metal, or element of group 13, 14 or 15;    b,o=1-3;    n"=0-6;    q=0 or 1;    R5=1-10C (halo)alkylene or 6-20C (halo)arylene (both optionally substituted and optionally having heteroatom);    R6=halo, or 1-10C (halo)alkyl or 6-20C (halo)aryl (both optionally having heteroatom), or X3R7;    X1-X3=O, S, or NR8;    R7,R8=H, or 1-10C (halo)alkyl or 6-20C (halo)aryl (both optionally substituted and optionally containing heteroatom);or    two or more R7+R8=ring.    (i) The adjacent carbon in the ring may mutually bond and carbon of R may be decreased; (ii) m R5 groups may be bonded; and (iii) n R6 groups may couple to form a ring. An INDEPENDENT CLAIM is included for nonaqueous electrolyte solution battery consists of a negative electrode which can occlude/release lithium ion, a positive electrode, and the nonaqueous electrolyte solution.
