Title: The Innovations of Nicole Viaud
Introduction
Nicole Viaud is a notable inventor based in Ville d'Avray, France. She has made significant contributions to the field of lead-acid battery technology, holding 2 patents that focus on improving the performance and durability of lead-antimony alloys used in electrode supports.
Latest Patents
Her latest patents include innovations in lead-antimony alloys for electrode supports for lead accumulators. The first patent addresses the grain size and resistance to corrosion of lead-antimony alloys containing less than 4% antimony and 0.005 to 0.1% copper. This invention improves these properties by incorporating a mixture of rare earths, preferably misch metal, in amounts ranging from 0.001 to 0.1%. The second patent focuses on low antimony alloys of lead used for casting electrode supports in lead accumulators. It emphasizes the importance of keeping antimony content below 4% to avoid poisoning effects on electrochemical processes. To reduce excessive grain size, the invention includes an additive of rare earths, such as misch metal, at a preferred concentration of 0.2%.
