ELECTRODE FOR ALL-SOLID-STATE BATTERY AND METHOD FOR MANUFACTURING ELECTRODE ASSEMBLY COMPRISING SAME

WIPO Patent Application WO/2020/231234

A1

According to the present invention, an all-solid-state battery electrode having low porosity can be obtained by adjusting concentrations of a slurry for forming an electrode active material layer and a slurry for forming a solid electrolyte layer. In an all-solid-state battery, which does not use a liquid electrolyte material but a solid electrolyte material, close contacts are required between battery component materials such as an electrode active material and a solid electrolyte material. When a method according to the present invention is applied, an electrode active material layer is filled with a solid electrolyte material and thus the component materials can come into close contact with each other, whereby the interfacial resistance properties are improved.
