Skills

I have hands-on experience in synthesizing sulfurized polyacrylonitrile (SPAN) cathodes using the chemical vapor deposition (CVD) technique. The resulting active material was processed into a slurry and uniformly coated onto carbon-coated aluminum foil using the Doctor Blade method to ensure consistent electrode thickness. The coated electrodes were then vacuum-dried to remove residual solvents and improve adhesion. This process provided me with strong practical skills in electrode fabrication, thin-film coating, and optimization of cathode preparation for lithium–sulfur battery applications.

I have extensive hands-on experience operating an MBRAUN inert atmosphere glovebox for the assembly of lithium-based coin cells. My work involves precise handling of air- and moisture-sensitive materials under controlled argon environments (O₂ and H₂O < 1 ppm). I routinely prepare and assemble CR2032 coin cells, ensuring proper electrode stacking, electrolyte filling, and cell sealing for electrochemical testing. This experience has strengthened my technical expertise in maintaining contamination-free conditions and ensuring reliable, reproducible battery performance measurements.

I am skilled in battery performance evaluation using advanced charge–discharge and electrochemical analysis systems. My experience includes operating the Neware CE-6000n series (20 V / 60 A) charge–discharge setup integrated with an environmental thermal chamber capable of controlling temperatures from –40 °C to 150 °C. I routinely test battery packs at various C-rates while monitoring real-time temperature profiles using thermocouples. For coin cell testing, I use a 5 V / 6 A Neware system to study charge–discharge behavior. In addition, I perform cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) using a Gamry potentiostat, enabling detailed analysis of redox kinetics, charge-transfer resistance, and electrochemical stability. These skills allow me to comprehensively assess the performance, reliability, and thermal behavior of advanced energy storage systems.

I have hands-on experience in measuring and analyzing thermal properties of advanced materials using multiple techniques. I use the Laser Flash Analysis (LFA) method with an LSR system to determine the thermal diffusivity of thermal interface materials (TIMs), as well as the thermal diffusivity, Seebeck coefficient, and electrical resistivity of 2D materials such as graphene. In addition, I perform thermogravimetric analysis (TGA) using the TA Instruments Q600 system to study material stability, decomposition behavior, and compositional analysis. These skills enable me to comprehensively evaluate the thermoelectric performance and thermal management potential of functional materials for energy and electronic applications.
