Abstract: There is provided a metal or metal-ion battery comprising an aluminum current collector and a low-corrosiveness non-aqueous electrolyte comprising, as a solvent, a carbonate compound of formula (I): This battery has an upper voltage limit of about 4.2 V or more and anodic dissolution of aluminum during battery operation at said voltage is suppressed.

Abstract: Compounds based on an element from Groupe IIIA (column 13) of the periodic table of the elements, such as boron, aluminum, gallium or indium, are here described, as well as their processes of preparation and their use as salts and/or additives, for instance, in combination with other salts in electrolyte compositions for electrochemical cells, inter alia, in electrolyte compositions in the presence of a liquid solvent and/or a solvating polymer, the electrolyte being in liquid, gel or solid form.

Abstract: Electrolyte compositions comprising lithium hexafluorophosphate, lithium 4,5-dicyano-2-(trifluoromethyl)imidazolate, a solvent, and at least one electrolytic additive, are herein described. The present application also describes the use if these electrolyte compositions in batteries, e.g. within a temperature range higher than or equal to 25° C.

Abstract: A method for making a Li-ion battery including the preparation of a positive electrode from an ink comprising at least one active electrode material, and at least one binder; the preparation of an electrode separator from an ink comprising at least one fluorinated copolymer; the preparation of a negative electrode from an ink comprising at least one active electrode material, and at least one binder. The fluorinated copolymer comprises: from 99.99 to 90 mol % of at least one fluorinated monomer; from 0.01 to 10 mol % of at least one acrylic acid derivative of formulae CR1R2?CR3—C(?O)—O—R4 wherein each of R1, R2, R3, equal or different from each other, is independently a hydrogen atom or a C1-C3 hydrocarbon group, and R4 is a hydrogen or a C1-C5 hydrocarbon moiety comprising at least one hydroxyl group.
