| Abstract | The present invention generally relates to the field of electrical energy storage in rechargeable secondary Li-ion batteries. More specifically, the invention relates to an electrode formulation for a Li-ion battery, comprising a binder based on a mixture of fluorinated polymers. The invention also relates to a method for preparing electrodes using said formulation by means of a solvent-free depositing technique on a metal substrate. The invention further relates to an electrode obtained by this method and to secondary Li-ion batteries comprising at least one such electrode.
La présente invention a trait de manière générale au domaine du stockage d'énergie électrique dans des batteries secondaires rechargeables de type Li-ion. Plus précisément, l'invention concerne une formulation d'électrode pour batterie Li-ion, comprenant un liant à base d'un mélange de polymères fluorés. L'invention concerne aussi un procédé de préparation d'électrodes mettant en œuvre ladite formulation, par une technique de dépôt sans solvant sur un substrat métallique. L'invention se rapporte enfin à une électrode obtenue par ce procédé ainsi qu'aux batteries secondaires Li-ion comprenant au moins une telle électrode. |
