Abstract

L'invention a trait à un procédé de préparation d'une cellule électrochimique pour batterie au lithium comprenant une électrode positive et une électrode négative disposées de part et d'autre d'un électrolyte gélifié comprenant les étapes suivantes : a) une étape de réalisation d'une cellule comprenant l'électrode positive, l'électrode négative disposées de part et d'autre d'une membrane comprenant au moins un polymère apte à gélifier au contact d'un solvant dinitrile ; b) une étape de mise en contact dudit assemblage avec une composition comprenant au moins un solvant dinitrile et au moins un sel de lithium, moyennant quoi la membrane se gélifie formant ainsi l'électrolyte gélifié.The invention relates to a method for preparing an electrochemical cell for a lithium battery comprising a positive electrode and a negative electrode arranged on either side of a gelled electrolyte comprising the following steps: a) a production step a cell comprising the positive electrode, the negative electrode arranged on either side of a membrane comprising at least one polymer capable of gelling on contact with a dinitrile solvent; b) a step of bringing said assembly into contact with a composition comprising at least one dinitrile solvent and at least one lithium salt, whereby the membrane gels thus forming the gelled electrolyte.
