Current leads corrosion and the problem of diagnostics of fluorocarbon-lithium cells

Corrosion behavior of niobium current leads of fluorocarbon-lithium cells are studied. Polarization measurements at plain niobium leads and at such leads in a contact with fluorocarbon cathode in an electrolyte of fluorocarbon-lithium cell were carried out. Besides, behavior of niobium lead directly in a feedthrough of real cells was studied. The contact of niobium with fluorocarbon cathode is shown to result in toughening of corrosion conditions and in possible niobium depassivation.

The review deals with studies of the properties of lead alloys used to fabricate electrode grids of sealed lead-acid batteries.

Glass Carent Lead of Lithium-Fluorocarbon Power Source

The influence of lithium-fluorocarbon glass leads on the stability and preservation, as well as the behavior of differentcurrent leads of insulator is studied. It is shown that the most resistant glass for lithium output is silicon-free glass C62. The behavior of the fluorocarbon cathode current lead (titanium, niobium, molybdenum-rhenium) during storage is investigated. Discovered high corrosion niobium current lead correlation between OCV element and the intensity of corrosion of niobium current lead.
