Abstract
The most widely used electrolyte for lithium-ion batteries was lithium hexafluorophosphate in a mixture of organic carbonate solvents.However,lithium-ion batteries containing lithium hexafluorophosphate-based electrolytes had poor stability at elevated temperatures( 60 ℃).Using1 H,13C,19 F NMR spectroscopy and1 H,13C,19 F coupling splitting were used to study the decomposition of the lithium hexafluorophosphate.It was found that the main products of decomposition were HF,PF5,O =PF3,O =PF2(OH) and O =PF(OH)2.
