ABSTRACT:
A highly alloyed nickel-containing ferritic stainless steel material for use as a cathode current collector for lithium solid cathode cells is provided. The material does not require costly melting practices and provides high corrosion resistance particularly where elevated temperature, 72.degree. C. or higher, storage and performance is required relative to other cathode current collector materials thereby increasing cell longevity.
