Estimating the term…
A non-aqueous electrolyte electrochemical cell comprises a negative electrode, a positive electrode, a non-aqueous electrolyte, a positive electrode case and a negative electrode case. The positive electrode case comprises a high-grade corrosion resistibility stainless steel having a pitting index between 30.5 and 45, the pitting index being calculated by the formula Cr %+3.times.Mo %+16.times.N %. An enhanced pressure sealed electrochemical cell can be manufactured in which the production cost of the positive electrode case is reduced and the productivity of the electrochemical cell improved by suppression of anodic oxidation of the positive electrode case.
