Title (EN) LITHIUM-ION RECHARGEABLE ACCUMULATORS INCLUDING AN IONIC LIQUID ELECTROLYTE
(FR) ACCUMULATEURS RECHARGEABLES LITHIUM ION COMPRENANT UN ÉLECTROLYTE LIQUIDE IONIQUE
Abstract: front page image
(EN)The invention relates to a lithium-ion rechargeable accumulator including a negative electrode in which the active material is graphite carbon, a positive electrode in which the active material is LiFePO4, and an ionic liquid electrolyte containing at least one ionic liquid of the formula C+A- in which C+ is a cation and A- is an anion, and at least one conducting salt, wherein the ionic liquid electrolyte further includes an organic additive consisting of vinyl ethylene carbonate (VEC).
(FR)L'invention concerne un accumulateur rechargeable lithium ion comprenant une électrode négative dont la matière active est du carbone graphite, une électrode positive dont la matière active est du LiFePO4, et un électrolyte liquide ionique comprenant au moins un liquide ionique de formule C+A- où C+ représente un cation et A- représente un anion, et au moins un sel conducteur, l' électrolyte liquide ionique comprenant en outre un additif organique qui est le carbonate de vinyléthylène (« vinyl ethylene carbonate » ou « VEC» en anglais).
