Title: Innovations of Rajshekar Das Gupta
Introduction
Rajshekar Das Gupta is a prominent inventor based in Toronto, Canada. He has made significant contributions to the field of electrochemistry, particularly in the development of advanced battery technologies. With a total of four patents to his name, his work focuses on enhancing the performance and stability of lithium-ion batteries.
Latest Patents
One of his latest patents is for a lithium-ion battery electrode with a uniformly dispersed electrode binder and conductive additive. This innovation relates to an electrode produced with a non-toxic solvent, resulting in a homogeneous mixture with uniform distributions of a conductive additive and a binder. The electrodes produced according to this disclosure feature a narrow binder particle size distribution, which distinguishes them from typical electrodes produced via a N-Methyl-Pyrrolidone (NMP) process. The resulting microstructure promotes the flow of current through the electrode and has improved cycling stability due, in part, to the binder's and the conductive additive's ability to bind with the active material particles used in the fabrication of the electrode.
Another notable patent is for a thin film electrochemical cell with a polymer double seal. This invention comprises a double-sealed thin film electrochemical pouch cell, which includes a cathode current collector, a cathode, an electrolyte, an anode, and an anode current collector. The cell is double-sealed by a first inner laminate layer forming a primary seal, which is covered by a second outer polymer layer forming a secondary seal. The second outer polymer layer comprises embedded particles to increase its thermal conductivity.
