  text: Due to the hydrolytic instability of LiPF6 in carbonate-based solvents, HF
    is a typical impurity in Li-ion battery electrolytes. HF significantly influences
    the performance of Li-ion batteries, for example by impacting the formation of
    the solid electrolyte interphase at the anode and by affecting transition metal
    dissolution at the cathode. Additionally, HF complicates studying fundamental
    interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion
    reduction, because it is electrocatalytically relatively unstable, resulting in
    LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing
    carbonate-based electrolytes are limited. We introduce and benchmark a simple
    yet efficient electrochemical in situ method to selectively remove ppm amounts
    of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the
    application of a suitable potential to a high surface-area metallic electrode
    upon which only HF reacts (electrocatalytically) while all other electrolyte components
    are unaffected under the respective conditions.
