    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： In a conventional electrochemical cell, since a welding between a container and a sealing plate is performed in the atmospheric air, a weld zone is oxidized and a corrosion resistance decreases. For this reason, impurities are eluted from the weld zone into an electrolyte, and this causes an internal resistance increase and a capacity decrease of the electrochemical cell. Further, there is a possibility that an organic solvent in the electrolyte is oxidized by the welding. According to the invention, in order to solve the above problems, the seal welding between the container and the sealing plate of the electrochemical cell is performed under an inert atmosphere.

    摘要： In an electrochemical cell in which a container is bonded to a cap, observation of liquid leakage has been needed in directions from four sides of the container, therefore much time and high cost have been required. The outer circumference of the cap is made to be smaller than that of the container, whereby surfaces for observing liquid leakage can be made to be only one surface in a direction from an upside of the cap, consequently an electrochemical cell can be provided at low cost.
