Abstract

La présente demande concerne une solution oligomère d'un électrolyte polymère, un électrolyte polymère et un dispositif électrochimique. La solution oligomère de l'électrolyte polymère comprend des monomères et une solution électrolytique. Les monomères forment des chaînes moléculaires polymères par polymérisation radicalaire, et ces chaînes se réticulent pour former un électrolyte polymère à structure de réseau tridimensionnelle. La solution électrolytique, composée d'un solvant organique à forte mobilité, pénètre dans les pores des électrodes, favorise le contact interfacial entre l'électrolyte polymère et les électrodes, améliore l'infiltration interfaciale, augmente la conductivité ionique, facilite le passage des ions lithium et améliore les performances électrochimiques de la batterie.
