Abstract
(EN)
The present invention provides a composition for an electrode mix with which it is possible to increase the adhesive strength between a current collector and an electrode mix layer in a battery such as a lithium ion secondary battery. This composition for an electrode mix has a configuration that includes a synthetic resin including 99 mass% or more of a vinylidene fluoride polymer, and a polyisocyanate compound in which at least some of the isocyanate groups are blocked by a blocking agent.
(FR)
La présente invention concerne une composition pour un mélange d'électrode avec lequel il est possible d'augmenter la force d'adhérence entre un collecteur de courant et une couche de mélange d'électrode dans une batterie telle qu'une batterie secondaire au lithium-ion. Cette composition pour un mélange d'électrode a une configuration qui comprend une résine synthétique comprenant 99 % en masse ou plus d'un polymère de fluorure de vinylidène, et un composé polyisocyanate dans lequel au moins certains des groupes isocyanate sont bloqués par un agent de blocage.
