Abstract:
A secondary battery includes a cathode, an anode, and an electrolyte layer including non-aqueous electrolytic solution and a polymer compound. The polymer compound includes a graft copolymer. The graft copolymer includes a block copolymer as a main chain, and includes one or both of a homopolymer and a copolymer as one or more side chains. The block copolymer includes, as polymerization units, vinylidene fluoride and hexafluoropropylene. The homopolymer includes, as a polymerization unit, one selected from the group consisting of vinylidene fluoride, hexafluoropropylene, monomethyl maleate, trifluoroethylene, chlorotrifluoroethylene, acrylic acid, and methacrylic acid. The copolymer includes, as polymerization units, two or more selected from the group consisting of vinylidene fluoride, hexafluoropropylene, monomethyl maleate, trifluoroethylene, chlorotrifluoroethylene, acrylic acid, and methacrylic acid.
Abstract:
A secondary battery includes a cathode, an anode, and non-aqueous electrolytic solution. The non-aqueous electrolytic solution includes a boron compound. The boron compound includes six or more boron (B) atoms, and includes an octavalent boron-hydrogen-containing structure represented by Formula (1), a dodecavalent boron-carbon-containing structure represented by Formula (2), or both.
Abstract:
An electrode material is provided. The electrode material includes a porous carbon material, wherein the porous carbon material has a half-width of diffraction intensity peak of a (100) face or a (101) face of 4 degrees or less with reference to a diffraction angle 2 theta on a basis of an X-ray diffraction method. An absolute value of a differential value of mass can be obtained when a mixture of the porous carbon material and S8 sulfur mixed at a mass ratio of 1:2 is subjected to thermal analysis, where temperature is employed as a parameter, has a value of more than 0 at 450° C. and a value of 1.9 or more at 400° C. A battery and method of manufacture are also provided.
