    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.

    摘要： A non-aqueous electrolyte secondary battery comprises at least a negative electrode, a positive electrode and a non-aqueous electrolyte. The negative electrode has an active material comprised of silicon or a silicon alloy containing lithium represented by composition formula Li.sub.x Si where x satisfies 0.ltoreq..times..ltoreq.5. The positive electrode has an active material comprised of a transition metal oxide. The non-aqueous electrolyte is a lithium ion-conductive non-aqueous electrolyte having at least one lithium compound comprised of one of an organic solvent and a solid polymer. The negative electrode active material is formed by absorption of lithium ions into the silicon resulting from an electrochemical reaction between the negative electrode and a lithium metal and/or a material containing lithium. A secondary battery having high voltage, high energy density, high reliability, improved current charge and discharge characteristics and a long cycle life is obtained.
