Abstract
Organophosphate/organofluorophosphate esters (O(F)PEs) in spent lithium-ion power batteries (LIPBs) may pose environmental and occupational health risks. In this study, we conducted suspect and nontarget screening using high-resolution mass spectrometry to characterize O(F)PEs in spent ternary LIPBs. Using diagnostic fragment ions at m/z 98.9837, 78.9587, and 98.9648, etc., we identified 41 O(F)PEs (tri/di/mono-OPEs, cyclic OPEs, OFPEs), including 14 first-reported compounds (confidence level ≥ 3). These compounds were ubiquitously detected across 16 spent ternary LIPB packs, indicating their pervasive occurrence. The predominant compounds–trimethyl phosphate, dimethyl hydrogen phosphate, and…
