8 Claims

1. An electrode for a lithium ion secondary battery, comprising a current collector, and an electrode active material layer comprising an electrode active material particle, the electrode active material layer being formed on at least one side of the current collector,

wherein the electrode comprises an electroconductive layer comprising solid electrolyte particles and electroconductive particles, between the current collector and the electrode active material layer,

wherein a particle diameter of the solid electrolyte particles is smaller than a particle diameter of the electrode active material particle, and greater than a particle diameter of the electroconductive particles, and

wherein the electroconductive layer is formed by a solid electrolyte-electroconductive particle complex in which the electroconductive particles are disposed on a surface of the solid electrolyte particles.
