Title:

SOLID ELECTROLYTE, BATTERY INCLUDING THE SAME, AND METHOD FOR MANUFACTURING THE SAME

Document Type and Number:

Japanese Patent JP2013140762

Kind Code:

A

Abstract:

To provide a Li_0.35La_0.55TiO₃-based solid electrolyte that can be made by sintering at low temperatures and has relatively high ionic conductivity.

A solid electrolyte of the present invention is a sintered body that satisfies at least one of the following conditions: a low-melting point material substitutes for a portion of the crystal structure of an oxide represented by the formula Li_pLa_(2-p)/3TiO₃, where 0<p≤0.5, the low-melting point material having a melting point lower than the sintering temperature of the oxide; the sintered body is mainly composed of the oxide and contains a low-melting point material that has a melting point lower than the sintering temperature of the oxide in addition to the oxide. The low-melting point material is preferably one or more selected from Bi, Li₂B₄O₇, and LiBO₂.
