摘要:
Die Erfindung betrifft ein Kompositmaterial (19) umfassend mindestens eine poröse Struktur aus mindestens einem thermisch stabilen Material und mindestens ein ionenleitfähiges Polymer, wobei das ionenleitfähige Polymer die Poren (49) der mindestens einen porösen Struktur im Wesentlichen vollständig ausfüllt. Das Kompositmaterial (19) kann vorteilhaft in einer elektrochemischen Festkörperzelle (1) zur Separation der Elektroden (21, 22) voneinander eingesetzt werden.
摘要:
A method of producing an organopolysulfide or salt thereof is provided which includes a step of mixing an organomonosulfide or salt thereof and elemental sulfur, wherein the mixing is carried out at a temperature not greater than 95C and in the absence of any added liquid phase for a time effective to produce the organopolysulfide or salt thereof. The described method makes possible the preparation of organopolysulfides and organopolysulfide salts without the use of solvent or catalyst.

Electrolyte pour batterie lithium-ion comprenant au moins un copolymère à blocs caractérisé en ce que ledit copolymère à blocs comprend au moins un segment polymérique A soluble dans ledit électrolyte et au moins un segment polymérique B doté d'une température de solubilisation « T » dans ledit électrolyte, les segments polymériques A et B étant présents en des quantités suffisantes pour permettre une augmentation de la viscosité de l'électrolyte préférentiellement jusqu'à la gélification de l'électrolyte à une température supérieure ou égale à la température « T », la conduction ionique étant réalisée par un solvant comprenant le copolymère et des sels de lithium.
摘要:
A heat-resistant material based on an amorphous thermoplastic polymer that is resistant to, but highly compatible with electrolyte solutions is disclosed. In an aspect, the heat-resistant material is used to form a separator for a battery cell and/or an electrolytic capacitor cell.
摘要:
Disclosed are: an amide compound having a specific structure in which an amine group has been substituted with an alkoxy group; and an electrolyte containing an ionisable lithium salt and electrochemical elements comprising the same. The electrolyte of the present invention has outstanding heat-stability and chemical stability and a wide electrochemical window. Further, the electrolyte exhibits adequately low viscosity and high ionic conductivity, and can hence be advantageously employed as an electrolyte for electrochemical elements employing diverse cathode materials.
摘要:
The present invention relates to a non-aqueous electrolyte for a lithium secondary battery and a lithium secondary battery containing the electrolyte. According to the present invention, the non-aqueous electrolyte for a lithium secondary battery containing electrolyte salt and organic solvent comprises: (a) a multi-functional compound containing two or more functional groups and having at least one acryl group among the functional groups; and (b) one anion receptor selected from the group consisting of borane, borate compounds, and mixtures thereof. A lithium secondary battery containing the non-aqueous electrolyte has a stable SEI membrane in the cathode, and the amount of LIF in the formed SEI membrane is controlled. Therefore, the lifetime of a battery is increased.
