Selection of cathode current collector materials using electrochemical techniques

Galvanic corrosion, cyclic and potentiodynamic polarization experiments were conducted to identify potential cathode current collector materials for the lithium silver vanadium oxide (Li/SVO) cell. Electrochemical tecnhiques were employed to study the corrosion response of 304L stainless steel, commercially pure Grade 1 titanium, and a high chromium ferritic stainless steel, Remanit 4575 Superferrit, in the Li/SVO cell environment. To obtain comparative qualitative information for candidate current collector materials, ASTM methods G5-87, G61-86, and G71-81 were used. Material response are displayed to potentiodynamic and cyclic polarization experiments. Electrochemical results are reported along with actual cell corrosion data
