    摘要: A non-aqueous electrolyte secondary battery capable of withstanding a reflow temperature has a positive electrode having a conductive material, a binder, and an electrode active material selected from the group consisting of LiCoO2, LiNiO2 and LiMn2O4. A negative electrode has a conductive material, a binder and an electrode active material selected from the group consisting of a titanium oxide having an anatase structure, lithium titanate having a spinel structure and a molybdenum oxide. An electrolyte has a supporting salt and a non-aqueous solvent having a boiling point greater than 200° C. A gasket is comprised of a material having a heat deformation temperature greater than 230° C. A separator is disposed between the positive electrode and the negative electrode and is comprised of a material having a heat deformation temperature greater than 230° C. At least one of the positive electrode and the negative electrode comprises an electrode heat-treated to a temperature of 250° C. to 450° C. for deactivating a thermally active portion of each of the conductive material, the binder and the electrode active material thereof.

    摘要: An electrochemical cell has an outer case formed of one of ceramics and glass. An electrochemical cell element is hermetically sealed in the outer case. The electrochemical cell element contains a positive pole, a negative pole, and a non-aqueous electrolyte containing an organic solvent. A metal layer is formed on an edge of the outer case. A sealing plate is resistance welded to the metal layer. The sealing plate is made of an alloy containing, in weight percentage, Co by 1 to 50%, Ni by 1 to 70%, Fe by 20% or higher, Cr by 10% or lower, Mn by 2.0% or lower, Si by 1.0% or lower and C by 1.0% or lower.
