About Mononita Das

PhD in Chemistry specializing in electrochemistry, batteries, and materials science, with 4+ years of research experience in developing cellulose-based composite separators and solid-state polymer/ceramic electrolytes for energy storage applications, including large-scale fabrication (roll-to-roll />100 g batch).My doctoral research demonstrated high-performance, thermally stable, and low-cost paper-based separators as sustainable alternatives to conventional polyolefin separators in lithium-ion batteries, and to NKK separators in supercapacitors. I have extensive experience working with LLZO and NZSP solid electrolytes for Li- and Na-metal cells, NVP-based cathodes for Na-ion batteries, and Si/C composite anodes for Li-ion batteries, with a strong focus on interface modification and electrochemical performance evaluation.I am proficient in cell fabrication, sol-gel and solid-state synthesis, advanced materials testing and electrochemical characterization, including XRD, SEM/TEM, EDX, XPS, TGA/DSC, CV, EIS, DRT, GCD, along with in-depth data interpretation and failure analysis. I have relevant knowledge in useful softwares like MATLAB, Python, FORTRAN77, ZView etc.My research interests lie in bridging materials design with interfacial stability, safety, scalability, and performance, and I am motivated to contribute to the development of sustainable, scalable, and high-performance materials for next-generation energy storage technologies.Apart from research, my other interests lie in reading books, practicing yoga and animal welfare.
