Application

  • Multifunctional potassium hexafluorophosphate passivate interface defects for high efficiency perovskite solar cells: Potassium hexafluorophosphate (KPF6) is used to enhance the interface between SnO2 quantum dots and perovskite (Z Wang et al., 2021).
  • Potassium hexafluorophosphate additive enables stable lithium–sulfur batteries: An optimized amount of KPF6 added to the electrolyte improves the cycling stability of lithium-sulfur batteries (J Li et al., 2020).
  • Dual electrolyte additives of potassium hexafluorophosphate and tris (trimethylsilyl) phosphite for anode-free lithium metal batteries: KPF6 and tris(trimethylsilyl) phosphite enhance the electrochemical performance of anode-free lithium metal batteries (TM Hagos et al., 2019).
