Abstract

La présente invention concerne un procédé de fabrication de maghémite. Plus spécifiquement, on fait réagir du NaBH4 avec du Fe(NO3)3·9H2O dans des conditions contrôlées de temps de réaction et de température de réaction pour obtenir de la lépidocrocite cristalline (γ-FeOOH) qui est ensuite traitée thermiquement dans un état gazeux non actif pour produire de la maghémite de haute pureté (γ-Fe2O3). L'application de la maghémite sur une cathode d'une batterie secondaire au lithium-soufre peut améliorer la capacité de décharge.
