摘要:
The present invention concerns thermotropic ionic liquid crystal molecules, comprising a so-called rigid part, a so-called flexible part bonded covalently, directly or via a spacer, to said rigid part, and one or more ionic groups bonded covalently to said rigid part. Said molecules can be used as electrolytes in an electrochemical device, in particular a lithium-ion battery.
摘要:
The invention relates to polymer compositions that conduct lithium ions, comprising the following ingredients: at least one ionic polymer from the polymerisation of an ionic liquid, the cation of which carries at least one polymerisable function; at least one lithium salt; and at least one non-ionic polymer, said composition being a solid composition, i.e. a composition devoid of water and organic solvent(s). The invention also relates to the use of said compositions for entering into the formation of elecrolytic membranes of electrochemical lithium generators.
摘要:
Interpenetrating polymer networks comprising a first network of polymer A formed from monomers, at least one of which contains an aromatic group functionalized with a cation-exchange group, and a second network of polymer B formed from monomers, at least one of which contains a fluorinated group (R F ). Use of these interpenetrating polymer networks for manufacturing fuel cell membranes.
