  • Publication number: 20200274195
    Abstract: In order to improve the safety of a rechargeable battery, methods for manufacturing the rechargeable battery using a solid-state electrolyte are being studied. However, a process of manufacturing the all-solid state rechargeable battery by separately preparing and laminating an electrode and a solid-state electrolyte is not only complicated, but also may cause side reactions due to residual moisture between the electrode and the solid-state electrolyte. In addition, additional processes are required to reduce the interface resistance between the electrode and the solid-state electrolyte. In order to solve these disadvantages, the present invention is to manufacture an integral all-solid state rechargeable battery by applying a mixed slurry of a conductive ceramic material and a polymer mixed with a solvent onto an electrode, evaporating the solvent, absorbing a liquid electrolyte, and then covering the electrode with a counter electrode.
