Title:
SLURRY COMPOSITION FOR LITHIUM SECONDARY BATTERY COMPOSITE ELECTRODE, METHOD FOR MANUFACTURING COMPOSITE ELECTRODE USING SAME, AND METHOD FOR MANUFACTURING LITHIUM SECONDARY BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2018/139868
Kind Code:
A1
Abstract:
A slurry composition for a lithium secondary battery composite electrode, a method for manufacturing a composite electrode using the same, and a method for manufacturing a lithium secondary battery including the same are provided. In the slurry composition for a composite electrode according to the present invention, a sulfide-based solid electrolyte powder, an electrode active material, and a binder are mixed in a solvent, wherein the solvent is a nonpolar solvent and may have a hydrogen bonding parameter (δh) of the Hansen solubility parameters of 4 to 7. According to the present invention, by providing a slurry composition for a composite electrode for electrostatic spray deposition and a method for manufacturing a composite electrode for a lithium secondary battery including the same, it is possible to control the thickness of the composite electrode to be formed and to enlarge the surface area thereof, and to improve bonding properties with a substrate.
