Abstract:
Provided is an all-solid-state lithium battery having greatly improved cycle performance when charging and discharging are repeatedly performed. The all-solid-state lithium battery according to the present invention is provided with: an oriented positive electrode plate having a thickness of 30 μm or more and constituted of an oriented sintered body; a solid-state electrolyte layer disposed on the oriented positive electrode plate and constituted of a lithium ion conducting material; and an intermediate layer having a thickness of 0.001-1 μm disposed on the solid-state electrolyte layer and comprising a metal capable of forming an alloy with lithium. In the oriented positive electrode plate, the oriented sintered body comprises a plurality of primary particles constituted of a lithium composite oxide having a layered rock salt structure, and the plurality of primary particles are oriented at an average orientation angle of over 0° and 30° or less with respect to the plate surface of the oriented positive electrode plate.
