Abstract:
(EN) Composite particles for lithium secondary battery positive electrodes, which contain coated active material particles and a binder, and wherein each of the coated active material particles comprises a positive electrode active material particle and a coating material that covers the surface of the positive electrode active material particle. The coating material contains a coating polymer that has a specific SP value, and optionally contains a conductive agent. A constituent element of secondary batteries, which uses the composite particles for lithium secondary battery positive electrodes; a secondary battery; a method for producing the composite particles for lithium secondary battery positive electrodes; and a method for producing the constituent element of secondary batteries.
(FR) L'invention porte sur des particules composites pour des électrodes positives de batteries secondaires au lithium, lesquelles particules contiennent des particules de matériau actif revêtu et un liant, et dans lesquelles chacune des particules de matériau actif revêtu comprend une particule de matériau actif d'électrode positive et un matériau de revêtement qui revêt la surface de la particule de matériau actif d'électrode positive. Le matériau de revêtement contient un polymère de revêtement qui présente une valeur PS spécifique, et qui contient, éventuellement, un agent conducteur. L'invention porte également sur un élément constitutif de batteries secondaires, lequel élément utilise les particules composites pour des électrodes positives de batteries secondaires au lithium ; sur une batterie secondaire ; sur un procédé pour produire les particules composites pour électrodes positives de batteries secondaires au lithium ; et sur un procédé pour produire l'élément constitutif de batteries secondaires.
