Title
(EN) CYCLIC SILOXANE-BASED COMPOUNDS AND SOLID POLYMER ELECTROLYTE COMPOSITION CONTAINING THE SAME AS A CROSSLINKING AGENT
(FR) COMPOSE A BASE DE SILOXANE CYCLIQUE ET COMPOSITION ELECTROLYTIQUE POLYMERIQUE SOLIDE CONTENANT CE COMPOSE EN TANT QU'AGENT DE RETICULATION
Abstract
(EN)
The present invention relates to a cyclic siloxane-based compound and a solid polymer electrolyte composition containing the same as a crosslinking agent, more particularly to a cyclic siloxane-based compound having a novel structure in which polyalkylene oxide acrylate groups are introduced into a cyclic siloxane compound and a solid polymer electrolyte composition containing the cyclic siloxane-based compound as a crosslinking agent along with other electrolyte components such as a plasticizer, lithium salt and a curing initiator. Since the solid polymer electrolyte composition of the present invention improves ion conductivity and electrochemical stability at room temperature, it can be useful as polymer electrolyte for electrolyte films, small-sized to high-capacity lithium-polymer secondary batteries, etc. Also, physical properties of the polymer electrolyte can be controlled easily by controlling the length of the polyalkylene oxide group in the cyclic siloxane-based crosslinking agent.
(FR)
L'invention concerne un composé à base de siloxane cyclique, ainsi qu'une composition électrolytique polymérique contenant ce composé en tant qu'agent de réticulation. L'invention concerne plus particulièrement un composé à base de siloxane cyclique présentant une nouvelle structure dans laquelle des groupes oxyde de polyalkylène-acrylate sont introduits dans un composé siloxane cyclique, ainsi qu'une composition électrolytique polymérique solide qui contient ce composé à base de siloxane cyclique en tant qu'agent de réticulation, ainsi que d'autres constituants électrolytiques tels qu'un plastifiant, du sel de lithium et un initiateur de durcissement. Comme la composition électrolytique polymérique solide selon l'invention augmente la conductivité ionique et la stabilité électrochimique à température ambiante, elle peut être utile en tant qu'électrolyte polymérique pour des films électrolytiques, des piles secondaires lithium-polymère du petit format à la grande capacité, etc. En outre, les propriétés physiques de l'électrolyte polymérique peuvent être facilement commandées par la longueur du groupe oxyde de polyalkylène dans l'agent de réticulation à base de siloxane cyclique.
