Title: Innovations by Inventor Sankar Das Gupta

Introduction

Sankar Das Gupta is a notable inventor based in Mississauga, Canada. He has made significant contributions to the field of electrochemistry, particularly in the development of advanced battery technologies. With a total of three patents to his name, his work focuses on improving 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 significant 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, covered by a second outer polymer layer forming a secondary seal. The second outer polymer layer comprises embedded particles to increase its thermal conductivity.
