Fluorinated Materials as Positive Electrodes for Li- and Na-Ion Batteries

Autor: Kévin Lemoine, Annie Hémon-Ribaud, Marc Leblanc, Jérôme Lhoste, Jean-Marie Tarascon, Vincent Maisonneuve

Publikováno v: Chemical reviews. 122(18)

Fluorine is known to be a key element for various components of batteries since current electrolytes rely on Li-ion salts having fluorinated ions and electrode binders are mainly based on fluorinated polymers. Metal fluorides or mixed anion metal flu

Mechanochemical synthesis of cobalt/copper fluorophosphate generates a multifunctional electrocatalyst

Autor: Nikolay Kornienko, Nina Heidary, Kévin Lemoine, Yoshiyuki Inaguma

Publikováno v: Chemical Communications. 56:9276-9279

The utilisation of inductive effects is emerging as a powerful tool to enhance material properties. Within the context of electrocatalysis, such effects may alter an active site's electronic structure and consequently, its catalytic activity. To this
