Abstract
An inorganic solid electrolytic rechargeable battery having positive and negative electrodes and an inorganic electrolyte interposed therebetween is provided. The positive and negative electrodes each contain an active material layer and a current collector layer. The positive electrode collector layer or the negative electrode collector layer is a conductive metal oxide layer. The negative electrode active material layer contains lithium metal or lithium alloys. This negative active layer may optionally be made of a material which provides an operation voltage potential of the negative electrode to be more noble than 1.0 V with respect to the potential of a metallic lithium.
