Patent

CA 2729900

The present invention concerns battery electrodes, and more particularly rechargeable lithium battery electrodes, with active materials, containing an inorganic binder for cohesion between the electrode materials and ad-hesion to a current collector. These electrodes are produced from an aqueous slurry of active electrode materials, optionally conductive additives and a soluble precursor or nanoparticles or a colloidal dispersion of the inorganic binder by spreading the slurry on a current collector and drying.

La présente invention concerne des électrodes de batterie, et plus particulièrement des électrodes de batterie au lithium rechargeable, avec des matériaux actifs, contenant un liant inorganique pour la cohésion entre les matériaux délectrodes et ladhésion à un collecteur de courant. Ces électrodes sont produites à partir dune pâte aqueuse de matériaux délectrodes actifs, optionnellement dadditifs conducteurs et dun précurseur soluble ou de nanoparticules ou dune dispersion colloïdale du liant inorganique en étalant la pâte sur un collecteur de courant et en séchant.
