Abstract: A nonaqueous electrolyte composition containing at least one organic isocyanide of formula (I) R—NC, wherein: R is selected from R1, (CH2)nL, and NP(R1)3; L is selected from carboxylic ester groups, S-containing groups, N-containing groups, and P-containing groups which are substituted by one, two or three R1; R1 is selected independently from C1-C10 alkyl, C3-C10 (hetero)cycloalkyl, C2-C10 alkenyl, C3-C7 (hetero)cycloalkenyl, C2-C10 alkynyl, C5-C7 (hetero)aryl, and C6-C13 (hetero)aralkyl, and n is an integer from 1 to 10; with proviso that C3-C10 (hetero)cycloalkyl is not morpholinyl.

Abstract: A nonaqueous electrolyte battery of the present invention includes a positive electrode having a positive active material capable of intercalating and deintercalating a lithium ion, a negative electrode having a negative active material capable of intercalating and deintercalating a lithium ion, a separator interposed between the positive electrode and the negative electrode, and a nonaqueous electrolyte. The heat generation starting temperature of the positive electrode is 180° C. or higher. The separator includes heat-resistant fine particles and a thermoplastic resin. The proportion of particles with a particle size of 0.2 ?m or less in the heat-resistant fine particles is 10 vol % or less and the proportion of particles with a particle size of 2 ?m or more in the heat-resistant fine particles is 10 vol % or less. The separator effects a shutdown in the range of 100° C. to 150° C.

Abstract: Sheet-shaped mixture layers are placed on both sides of a current collector to form an electrode (positive electrode) with a layered structure. The electrode with a layered structure and a counter electrode (negative electrode) thereof are wound via a separator, while a positional shift in a winding direction is caused between the current collector and the sheet-shaped mixture layers of the electrode with the layered structure, whereby a winding body is formed. The winding body is placed in a battery case (outer can) to constitute a battery. Particularly, in the electrode with a layered structure, by forming the current collector of a plain-woven wire net, a metal foil, expanded metal, a lath, or punching metal, a battery with satisfactory productivity suitable for an intermediate load can be provided at a low cost.
