摘要:
The present invention relates to copolymers, to a process for their preparation and to their use for the production of ionically conductive materials. A copolymer according to the invention consists of monomer units corresponding to the formula --CH.sub.2 --O--CHR--CH.sub.2 O (I) and monomer units corresponding to the formula --CH.sub.2 --CHR'--O-- (II), in which: R denotes a hydrogen atom, a linear or branched alkyl radical containing from 1 to 8 carbon atoms or a radical CH.sub.3 (--O--CH.sub.2 --CH.sub.2).sub.n --O--CH.sub.2 --, in which 1.ltoreq.n.ltoreq.10; R' denotes an aliphatic radical containing an unsaturation which can be polymerized by a radical route and inert in the conditions of cationic polymerization. The copolymers can be obtained by cationic polymerization of the appropriate oxirane and dioxolane. Application to the production of ionically conductive materials.
摘要:
In some embodiments, the present disclosure pertains to energy storage compositions that comprise a clay and an ionic liquid. In some embodiments, the clay is a bentonite clay and the ionic liquid is a room temperature ionic liquid (RTIL). In some embodiments, the clay and the ionic liquid are present in the energy storage compositions of the present disclosure in a weight ratio of 1:1. In some embodiments, the ionic liquid further comprises a lithium-containing salt that is dissolved in the ionic liquid. In some embodiments, the energy storage compositions of the present disclosure further comprise a thermoplastic polymer, such as polyurethane. In some embodiments, the thermoplastic polymer constitutes about 10% by weight of the energy storage composition. In some embodiments, the energy storage compositions of the present disclosure are associated with components of energy storage devices, such as electrodes and separators. In some embodiments, the energy storage compositions of the present disclosure are associated with an energy storage device, such as a battery or a capacitor.
