Title (EN) THIN APROTIC ELECTROLYTE FILMS, IMMOBILIZED LIQUID MEMBRANE CONDUCTORS, AND BATTERIES
(FR) COUCHES MINCES D'ELECTROLYTE APROTIQUE, CONDUCTEURS A MEMBRANE LIQUIDE IMMOBILISES ET BATTERIES
Abstract:
(EN) Thin aprotic electrolyte films and immobilized liquid membrane conductors which can easily be reduced in the thickness or enlarged in the area are excellent in the retention of an aprotic electrolyte solution over a wide temperature range and improved in long-term stability and mechanical strengths, and are produced by impregnating a polyolefin film with an aprotic electrolyte solution to make the electrolyte solution immobilized by the film, the polyolefin film being one made from a polyolefin composition comprising a main skeleton made of a polyolefin excellent in solvent resistance, a terminal chain made of an end-modified polypropylene having a functional group having an affinity for the solvent of the electrolysis solution to be used, and if necessary an electronically conducting material. Batteries are made by using them.
(FR) L'invention concerne des couches minces d'électrolyte aprotique ainsi que des conducteurs à membrane liquide immobilisés dont on peut réduire facilement l'épaisseur ou dont on peut agrandir la surface, caractérisées par une excellente rétension de la solution d'électrolyte aprotique sur une large gamme de températures et une meilleure stabilité à long terme ainsi que de meilleures résistances mécaniques. Leur production consiste en l'imprégnation d'une couche mince de polyoléfine avec une solution d'électrolyte aprotique pour rendre la solution d'électrolyte immobilisée par la couche mince, la couche mince de polyoléfine étant constituée d'une composition de polyoléfine comprenant un squelette principal en polyoléfine présentant une excellente résistance aux solvants, une chaîne terminale en polypropylène à modification terminale présentant un groupe fonctionnel ayant une affinité pour le solvant de la solution d'électrolyse à utiliser, et si nécessaire un matériau conducteur électroniquement. Leur utilisation permet de produire des batteries.
