Abstract:
This paper investigates the effect of electrolyte systems containing lithium hexafluorophosphate (LiPF6) and lithium tetrafluoroborate (LiBF4) as mixed solutes on LFP//Li batteries at low temperatures. It was found that electrolytes containing LiBF4 exhibited lower polarisation and superior electrochemical performance at low temperatures, with a capacity of 84.55 mAh g-1 at -20 °C and 0.2C (capacity retention of 95.3%). Furthermore, the LFP electrode after cycling exhibited a richer inorganic structure dominated by boron and fluorine-based inorganic compounds.
