摘要： The invention concerns ionic compositions with high ionic conductivity, comprising a salt with delocalized anionic charge. An ionic composition comprises a salt dissolved in a solvent and has a conductivity higher than 10?-5 S.cm-1¿ between -30 °C and 150 °C. The cation is a proton, a hydronium, a hydroxonium, a nitrosonium NO+, an ammonium -NH¿4?+, or an organic or organometallic metal cation. The anion is a carbanion bearing a perfluorinated substituent or a substituent bearing at least a F on the α carbon of the carbanion, and two non-perfluorinated electroattractive substituents. Said composition can be used as electrolyte in electrochemical devices, as catalyst for chemical reactions, as photochemical or thermochemical initiator for polymerisation or cross-linking reactions.

摘要： The invention concerns a method for producing a multilayer material based on active lithium, consisting of the deposition of an active lithium film on a protection layer with a sufficient speed to substantially avoid oxidation of the lithium and/ or over a sufficient period such that the adhesion of the lithium occurs upon contact with the protection layer. A multilayer material of the invention presents excellent impedance stability and absence of dendrite formation after the cycling process, when incorporated into an electrochemical battery as anode. The batteries, the anode of which is composed of a multilayer material of the invention are particularly efficient with respect to their coulombic efficiency.
