Research AssistantApplied Physics And Applied Mathematics At Columbia University Feb 2023 - Nov 2023New York, United States·Synthesized TAPB-PDA and Tp-Tta COF film through self-assembly on copper foil substrate. Characterization with SEM, XRD, FIB. Test the mechanical property and chemical stability in electrolyte of the COF. Choose Cu with TAPB-PDA COF film as current collector to manufacture the anode-free pouch cell.·Adjust the morphology and thickness of COF film on Cu with different reaction time and condition. Find 16h COF(0.7um) significantly increase the number of battery cycles with essentially no reduction in battery efficiency in 10g/Ah electrolyte. The mechanism is COF film allows Li ions to pass through it selectively with its pore size(1.4nm) and inhibits the Li dendrite grow on the Cu through its mechanical strength.·Use 5wt% TMP-TMA polymer to solidify/lock the LiDFOB/LiBF4( in FEC-DEC) dual-salt electrolyte to improve its stability to resist the puncture of Li dendrite, increasing the durability and safety of battery. Wet the pore of COF with electrolyte to avoid polymer blockage in it, because the blockage will prevent Li ion to pass through the film and increase the cell polarization. -
