Title (EN) GEL-TYPE POLYMER ELECTROLYTE AND USE THEREOF
(FR) ELECTROLYTE POLYMERE GELIFORME ET SON UTILISATION
Abstract: front page image
(EN)A gel-type polymer electrolyte, wherein said polymer comprises(A) an ethylene-unsaturated carboxylic acid copolymer or aderivative thereof and (B) a polyalkylene oxide having a hydroxylgroup at one terminal thereof or a derivative thereof, which arebonded together by an ester bond. The gel-type polymer electrolytehas a high ionic conductivity, and makes it possible to provides acell which has excellent charge/discharge characteristics at low temperatures as well as at high temperatures.
(FR)L'invention concerne un électrolyte polymère géliforme. Ledit copolymère comprend (A) un copolymère d'acide carboxylique insaturé par éthylène ou un de ses dérivés et (B) un oxyde de polyalkylène ayant un groupe hydroxyle à une de ses terminaisons ou un de ses dérivés, qui sont liés mutuellement par une liaison ester. Cet électrolyte polymère géliforme présente une conductivité ionique élevée et permet d'obtenir une cellule comportant d'excellentes caractéristiques en matière de charge/décharge à basses températures comme à températures élevées.
