I have been continuously learning and upgrading knowledge on Li-ion Battery, Na-ion Battery, Dual-ion Battery, Redox-Flow Battery and Li-CO2 Battery. Some of the selective achievements and skills Chemical modification of Silicon for LIB anode 4 minutes charging battery by our daily using Caffeine Discovery of alternative anode for graphite, Sulfur-doped Hard CarbonExploring Polybenzothiophene both as anode and cathode for bipolar battery Tuning the redox states of Polyanilines for metal-free dual-ion battery Electrochemical analysis of Li-containing cathode with various electrolytesFine-tuning in synthesis of hard carbon, organic materials, polymers and nanomaterials
