Abstract
Official abstract text for this publication.
A binder solution for an all-solid-state battery, an electrode slurry for an all-solid-state battery including the same and a method of manufacturing an all-solid-state battery using the same, and more particularly to a binder solution for an all-solid-state battery, in which a polymer binder configured such that a non-polar functional group is bonded to the end of a polar functional group is used, whereby the polar functional group is provided by a deprotection mechanism of the polymer binder through a thermal treatment, thus increasing adhesion between electrode materials to thereby improve battery capacity and enabling a wet process to thereby reduce manufacturing costs, an electrode slurry for an all-solid-state battery including the same and a method of manufacturing an all-solid-state battery using the same.
First claim
Opening claim text (preview).
What is claimed is: 1 . A binder solution for an all-solid-state battery, comprising: a polymer binder comprising at least one selected from the group consisting of compounds represented by Chemical Formula 7 below to Chemical Formula 10 below; and a solvent: wherein n is an integer from 100 to 5000, inclusive, and * represents a bonding site.
