摘要： The invention relates to a method of manufacturing a separating membrane in gel form, for an alkali metal ion battery, the method consisting of extruding a mix comprising: an alkali metal salt, a dinitrile compound with formula N≡C—R—C≡N, in which R is a hydrocarbon group CnH2n, and n is equal to 1 or 2 and preferably equal to 2, a hot melt support polymer, soluble in the dinitrile compound.

摘要： The present invention concerns a metal-oxygen battery containing, as the electrolyte, a monophasic electrolytic solvent medium having at least an alkali metal or alkaline earth metal supporting salt, preferably a lithium salt; a fluorocarbon solvent having an oxygen solubility at least equal to 30% v/v; 10 to 60% by volume of at least fluorinated solubilising agent; and a carbonate solvent. The fluorinated solubilising agent is different from the fluorocarbon solvent; is chosen from the mono-, poly- and perfluorinated, saturated, unsaturated and/or aromatic, linear, branched and/or cyclic hydrocarbon compounds; and has 4 to 18 carbon atoms with the carbon chain having at least one polar end unit and can be interrupted by one or more heteroatoms of oxygen and sulfur atoms and radicals —N(R1)-, —B(R1)- and —P(R1R2)- in which R1 a d R2, identical or different, represent a hydrogen atom or a C1 to C4 alkyl radical.

摘要： The invention relates to a bipolar lithium-ion battery comprising n electrochemical cells (C1, C2, C3) connected in series, n being an integer greater than or equal to 2. Each cell comprises a positive electrode (P1, P2, P3), a current collector (2) supporting the positive electrode, a negative electrode (N1, N2, N3), a current collector (8) supporting the negative electrode, and an electrolyte placed between each pair of positive and negative electrodes. In said battery, a so-called “common” current collector (4, 6) from each cell is integral with the current collector from an adjacent cell, the common current collector (4, 6) supporting an electrode of each polarity, and at least the n−1 common current collectors are made of a material formed of carbon fibers.
