This all-solid-state lithium-ion secondary battery comprises the following layered together in an alternating fashion: battery cells each provided with a positive electrode, a solid electrolyte layer, and a negative electrode; and collectors that provide electrical conductivity between adjacent battery cells. Said all-solid-state lithium-ion secondary battery is characterized in that each collector is provided with an electron conduction layer containing electron-conducting inorganic particles and a low-melting-point glass for binding said inorganic particles together. In an all-solid-state lithium-ion secondary battery with the above design, the inorganic particles between the electrodes and the collectors form electron-conducting paths, and the low-melting-point glass between the particles improves the characteristics of the joins between the collectors and the electrodes. This makes it possible to provide an all-solid-state lithium-ion secondary battery that exhibits low electronic resistance and a low rate of resistance increase per charge/discharge cycle. |
