The present disclosure relates to a binder solution having lithium ion conductivity for an all-solid-state battery and an electrode slurry including the same. Specifically, the binder solution includes a first binder having high binding force, a second binder having higher lithium ion conductivity than that of the first binder, a lithium salt, and an organic solvent that dissolves the lithium salt.

Binder solution having lithium ion conductivity for all-solid-state battery and electrode slurry comprising same

A method of manufacturing an electrode for an all-solid-state battery is performed in a dry manner using first and second rollers. An electrode for an all-solid-state battery having an electrode layer with a desired thickness and a desired density of a mixture material may be manufactured by adjusting conditions of the first and the second rollers. The manufacturing speed may be accelerated, because there is no drying process, so that the efficiency of the manufacturing is improved. The process of thickening an electrode is realized by using the method and the porosity of the electrode for an all-solid-state battery manufactured thereby is excellent.

An improved, low porosity, solid electrolyte membrane and a method of manufacturing the solid electrolyte membrane are provided. The low porosity, solid electrolyte membrane significantly improves both mechanical strength and porosity of the membrane, inhibits the growth of lithium dendrites (Li dendrites), and thereby maintains and maximizes electrochemical stability of an all-solid-state battery. This is accomplished by wet-coating a sulfide or oxide solid electrolyte particle with a thermoplastic resin, or a mixture of the thermoplastic resin and a thermosetting resin, using a solvent to prepare a composite and hot-pressing the composite at a relatively low temperature and at a low pressure.
