Abstract
(EN)
A preparation method for a cross-linked polymer electrolyte, and a semisolid polymer battery and a preparation method therefor. A cyclic borate ester with two terminal groups as alkenyl groups is taken as a cross-linking agent to cause in-situ polymerization of a polymer monomer and the like on a support material, to obtain a cross-linked polymer electrolyte. The preparation method for the electrolyte is simple; the polymer electrolyte has small interface resistance and good compatibility with an electrode, and has good mechanical properties, high electrical conductivity, and a great transport number; the polymer battery assembled using the polymer electrolyte has good stability and rate performance.

L'invention concerne un procédé de préparation d'un électrolyte polymère réticulé, ainsi qu'une batterie polymère semi-solide et un procédé de préparation associé. Un ester de borate cyclique avec deux groupes terminaux en tant que groupes alcényle est pris comme agent de réticulation pour provoquer la polymérisation in situ d'un monomère polymère et équivalents sur un matériau de support, pour obtenir un électrolyte polymère réticulé. Le procédé de préparation de l'électrolyte est simple ; l'électrolyte polymère présente une faible résistance d'interface et une bonne compatibilité avec une électrode, et présente de bonnes propriétés mécaniques, une conductivité électrique élevée, et un grand nombre de transport ; la batterie polymère assemblée à l'aide de l'électrolyte polymère présente de bonnes performances de stabilité et de vitesse.
