The invention provides a non-aqueous electrolyte solution containing a phosphonosulfonic acid compound represented by formula (I): 

Non-aqueous electrolyte solution containing phosphonosulfonic acid compound, and lithium secondary battery

A non-aqueous electrolyte solution containing a cyclic sulfone compound having a 1,3-dithietane-1,1,3,3-tetraoxide structure is provided. The cyclic sultone compound is preferably a compound represented by formula (I) [wherein in formula (I), Rto Reach represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, or the like]. 

Nonaqueous electrolyte solution containing cyclic sulfone compound, and lithium secondary battery

A non-aqueous electrolyte solution containing a cyclic sulfate compound represented by formula (I) is provided, wherein in formula (I), Rrepresents a group represented by formula (II) or a group represented by formula (III); Rrepresents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, a group represented by formula (II), or a group represented by formula (III); and in formula (II), Rrepresents a halogen atom, an alkyl group having from 1 to 6 carbon atoms, a halogenated alkyl group having from 1 to 6 carbon atoms, an alkoxy group having from 1 to 6 carbon atoms, or a group represented by formula (IV). 

Cyclic sulfate compound, non-aqueous electrolyte solution containing same, and lithium secondary battery

The present invention provides a non-aqueous electrolytic solution for a lithium secondary battery, wherein the lithium secondary battery includes, as a cathode active material, a composite oxide in which at least 35% by mole of a transition metal included in the composite oxide is manganese, and wherein the non-aqueous electrolytic solution includes an unsaturated sultone.

A heat treatment was carried out in a pressurized condition on an amorphous metal ribbon containing Fe and Co as main components and being represented by the general formula: (CoFe)XY. (In the formula, X represents at least one species of element selected from Si, B, C and Ge, Y represents at least one species of element selected from Zr, Nb, Ti, Hf, Ta, W, Cr, Mo, V, Ni, P, Al, Pt, Rh, Ru, Sn, Sb, Cu, Mn and rare earth elements, c, a and b satisfy 0&#x2266;c&#x2266;1.0, 10&#x3c;a&#x2266;35 and 0&#x2266;b&#x2266;30, respectively, and a and b are represented in terms of atomic %.) By carrying out a heat treatment in a pressurized condition in the same manner on a magnetic substrate comprising an amorphous metal ribbon and a heat resistant resin or a laminate of the substrates, not only the magnetic properties but also the mechanical properties and the processability are improved. The substrates can be used in antennas, which are devices that convert an electric wave to an electric signal, rotors and stators of electric motors and so on.

Magnetic substrate, laminate of magnetic substrate and method for producing thereof
