摘要： A method of manufacturing an all-solid-state battery includes forming an anode active material layer on surfaces of an anode current collector, forming a first solid electrolyte layer covering exposed surfaces of the anode active material layer to form a symmetrical electrode structure, pressing the structure at a preliminary pressing pressure lower to form an anode, forming a cathode active material layer on a surface of cathode current collectors, the cathode active material layer being smaller than the cathode current collectors, forming a second solid electrolyte layer covering the cathode active material layers and the cathode current collectors to form first and second cathodes, forming a laminate by laminating the cathodes on opposite surfaces of the anode, the second solid electrolyte layers of the cathodes facing the anode, and pressing the laminate at the final pressing pressure.

摘要： A system and method of estimating the state of health of an all-solid-state battery are provided to detect the amount of hydrogen sulfide that is generated in all-solid-state battery cells and using the amount as a factor for estimating the state of health of the battery. The method of estimating a state of health (SOH) of an all-solid-state battery includes detecting whether hydrogen sulfide is generated in each cell of the all-solid-state battery, and estimating the state of health of the all-solid-state battery corresponding to an amount or an increase rate of generated hydrogen sulfide based on data prepared in advance.
