  • Publication number: 20130323566
    Abstract: A thin secondary battery with a power-generating element 10 including positive electrode sheets 12 and negative electrode sheets 14 stacked with separators 5 interposed therebetween, wherein the outermost positive electrode sheet 12 of the power-generating element 10 includes a first resin layer 6a, instead of a positive electrode active material layer 1, on an outer surface of a positive electrode current collector 2, the outermost negative electrode sheet 14 of the power-generating element 10 includes a second resin layer 6b, instead of a negative electrode active material layer 3, on an outer surface of a negative electrode current collector 3, and the first and second resin layers 6a and 6b cover the power-generating element 10, and are bonded to each other at peripheral portions 9 surrounding the power-generating element 10, thereby hermetically sealing the power-generating element 10.

  • Publication number: 20090233176
    Abstract: An object of the present invention is to provide a non-aqueous electrolyte secondary battery that is excellent in cycle characteristics even in a high-temperature environment and high in thermal stability. The non-aqueous electrolyte secondary battery of the present invention comprises at least one of an active material A and an active material C, and an active material B as positive electrode active materials. The active material A is LixCoO2 (0.9?x?1.2). The active material B is LixNiyMnzM1-y-zO2 (0.9?x?1.2, 0.1?y?0.5, 0.2?z?0.5, 0.2?1?y?z?0.5 and 0.9?y/z?2.5; and M is at least one selected from the group consisting of Co, Mg, Al, Ti, Sr, Ca, V, Fe, Y, Zr, Mo, Tc, Ru, Ta, W and Re). The active material C is LixCo1-aMaO2 (0.9?x?1.2 and 0.005?a?0.1; and M is at least one selected from the group consisting of Mg, Al, Ti, Sr, Mn, Ni, Ca, V, Fe, Y, Zr, Mo, Tc, Ru, Ta, W, Re, Yb, Cu, Zn and Ba).
