Project 1: Process Optimization of Natural Graphite Anodes for Comparative Supplier Evaluation • Optimized the natural graphite anode process, resulting in a first discharge capacity above 370 mAh/g. • Performed root cause analysis on process variation using viscosity test, TGA and SEM, correlating microstructural changes with performance deviation • Prepared and tested coin cells, generating capacity data and cycle performance insights to guide optimization. • Standardized the process in mixing, drying, calendaring and coin cell making to reach consistent performance. Project 2: SOP for Ion Chromatograph & Mass Spectrum (IC-MS) Lithium-ion Batteries Electrolyte Test • Established an SOP for IC-MS electrolyte analysis, improving accuracy in ion identification and quantification. • Developed parameter setting and data process method for routine analytes, enabling higher reproducibility. • Designed a new test method, achieving clearer peak resolution and more precise electrolyte characterization.
Project 1: Optimization of Cathode Coating for Enhanced Performance in Solid-State Batteries • Engineered co-polymers coating on the LFP, NMC cathode and PEO electrolyte, enhancing cell performance. • Synthesized novel copolymers with perfluoro and sulfonate groups via ATRP, expanding the function of coating. • Evaluated coating performance through potentiostat and cycle test, confirming the improved stability and capacity. Project 2: Synthesis and Performance Evaluation of DNDA • Optimized the synthesis process of polyimide precursor (DNDA), increasing yield from 35% to 58%. • Engineered fluid mixing system (venturi + peristaltic pump), improving 3 phase precursor mixing uniformity.
