Title: Innovations of Dipankar Roy in Solid Organic Electrolytes

Introduction

Dipankar Roy is an accomplished inventor based in Potsdam, NY (US). He has made significant contributions to the field of solid organic electrolytes, holding two patents that showcase his innovative work. His research focuses on the synthesis and characterization of organic electrolytes that have promising applications in various technologies.

Latest Patents

Dipankar Roy's latest patents involve the development of solid organic electrolytes consisting of alkylimidazolium cations with alkyl, PEGylated, and fluorinated side chains of varying molecular weights. These electrolytes exhibit a conductivity of approximately 2×10 S/cm at 30°C. Notably, the ionic conductivity can be significantly enhanced to 1.11×10 S/cm at 30°C and 2.88×10 S/cm at 90°C by blending the PEGylated/fluorinated imidazolium iodide with another solid electrolyte, 1-ethyl-3-methylimidazolium iodide (EtMImI). The synthesized PEGylated imidazolium iodides demonstrate conductivities ranging from 1.6×10 S/cm to 2×10 S/cm at 30°C, with viscosities between 620 cP and 720 cP at the same temperature. Importantly, these organic electrolytes can function without the addition of inorganic salts such as LiI or KI, as the iodide counter ion provides the necessary anion for the I/I redox mediators in dye-sensitized solar cells (DSSCs). The thermal stability of these electrolytes extends to high temperatures, ranging from 250°C to 300°C.
