Abstract

La présente invention concerne un générateur électrochimique au lithium comportant au moins une électrode composite comprenant un matériau actif, et un premier et un second électrolyte solides distribués de façon non-homogène dans le composite. Le premier électrolyte solide est de nature minérale, vitreux ou partiellement vitreux, et est un conducteur spécifique des ions lithium, et est localisé préférentiellement en surface des particules du matériau actif de l'électrode. Le second électrolyte solide est de nature organique, comprend un électrolyte polymère sec ou gélifié conducteur mixte des ions répartis autour des phases solides dispersées et agissant comme liant déformable, préférablement de façon élastomérique, du composite en contact également avec le collecteur et l'électrolyte séparateur du générateur. Une mince couche du premier électrolyte mouille et recouvre au moins une partie de la surface des particules du matériau actif de façon à protéger la surface recouverte des réactions de passivation ou de dégradation induites par le second électrolyte, et à maintenir la qualité des échanges ioniques et électroniques entre la matière active de l'électrode et les autres constituants du composite, le premier électrolyte étant imperméable aux composantes du second électrolyte.
