Abstract
Official abstract text for this publication.
A main object of the present disclosure is to provide an all solid state battery in which the reversibility of the deposition and dissolution reaction of a metal Li can be improved while inhibiting an occurrence of short circuit. The above object is achieved by providing an all solid state battery utilizing a deposition and dissolution reaction of a metal Li as an anode reaction, the all solid state battery comprising: an anode current collector, a porous layer comprising a resin, a solid electrolyte layer, a cathode active material layer, and a cathode current collector, in this order; wherein an electric resistance of the porous layer is 1Ω or more and 690Ω or less; and a thickness of the porous layer is 14 μm or less.
