Overview

LiBF4 offers better low-temperature performance and high-voltage tolerance than LiPF6 but lower conductivity, and is mostly used as an additive or as the electrolyte in lithium primary batteries. It can improve low-temperature discharge and high-voltage cycling.

  • Good low-temperature performance
  • High-voltage tolerance
  • H₂O ≤ 20 ppm
