Abstract
Disclosed are a current collector having a primer layer comprising a conductive material and a binder having a three-dimensional network structure, an electrode for an all-solid-state battery comprising the current collector, an all-solid-state battery comprising the same, and a method for manufacturing the electrode for the all-solid-state battery.
Claims20
A current collector comprising:
- a substrate;
- and
- a primer layer disposed on the substrate,
- wherein the primer layer comprises a conductive material and a binder having a three-dimensional network structure,
- wherein the binder of the three-dimensional network structure comprises a crosslinking between a polymer having an unsaturated bond and a vulcanizing agent.

A method for manufacturing an electrode for an all-solid-state battery, the method comprising:
- preparing a primer layer slurry comprising a conductive material, a polymer having an unsaturated bond, and a vulcanizing agent;
- applying the primer layer slurry on a substrate so as to have a predetermined thickness and drying the primer layer slurry to form a primer layer on the substrate;
- additionally applying and drying an electrode slurry comprising an electrode active material and a solid electrolyte on the primer layer to form an electrode layer on the primer layer;
- and
- drying the primer layer under a temperature condition of 120° C. or higher and 180° C. or lower to perform a crosslinking between the polymer having the unsaturated bond and the vulcanizing agent.
