TTFP {Tris(2,2,2-trifluoroethyl) Phosphite} is a multi-functional additive primarily designed to enhance the stability and performance of high-voltage LIBs, especially those utilizing lithium-rich layered oxide (LRLO) or high-nickel (NCM) cathodes. TTFP is mainly used to address the severe stability issues that arise when charging cathodes to high voltages (>4.5 V). The multifunctional roles of TTFP are shown below: (1) Cathode Protection (CEI Formation); (2) Oxygen Scavenger; (3) Aluminum Current Collector Passivation.
