Title: The Innovative Contributions of Stephane Senyarich
Introduction
Stephane Senyarich is a notable inventor based in Mornac, France. He has made significant contributions to the field of electrochemistry, particularly in the development of advanced alkaline electrolyte secondary electric cells. With a total of four patents to his name, Senyarich's work has had a considerable impact on energy storage technologies.
Latest Patents
One of Senyarich's latest patents is a method of forming a separator for alkaline electrolyte secondary cells. This invention involves an alkaline electrolyte secondary electric cell that comprises at least one positive electrode and one negative electrode positioned on either side of a separator made from polyolefin fibers grafted with a vinyl monomer. The cell also includes a device for absorbing and retaining nitrogen in a strongly basic medium, with a pH of at least 12, which is constituted by the separator. The process involves forcing a vinyl monomer solution into the pores of the separator using a suction pump.
Another significant patent is for a hydrophilic electrode designed for an alkaline electrochemical cell. This negative electrode consists of an active material and a hydrophilic agent made up of small cylindrical rods of polyolefin that are equipped with hydrophilic groups. The rods have a mean length of less than 50 microns and a mean diameter of less than 20 microns. The manufacturing method involves fragmenting long polyolefin fibers by oxidizing them, mixing the resulting rods with the active material, and applying the mixture to a current conductor.
