Solid electrolyte battery

摘要

A solid electrolyte battery attempted to raise a utilization rate of electrodes thereof and improve cycle characteristics, the solid electrolyte battery incorporating a positive electrode; a solid electrolyte layer formed on the positive electrode; and a negative electrode formed on the solid electrolyte layer, wherein the solid electrolyte layer has a multi-layer structure having two or more layers, a solid electrolyte layer of the layers constituting the solid electrolyte layer having the multi-layer structure which is nearest the positive electrode is constituted by a polymer having a glass transition point of - 60 DEG C or lower when measurement is performed by using a differential scanning calorimeter and a number average molecular weight of 100,000 or larger, and at least one of the layers constituting the solid electrolyte layer having the multi-layer structure except for the layer nearest the positive electrode is formed by crosslinking a polymer solid electrolyte having a functional group which can be crosslinked.
