Abstract
The present invention relates to a method of preparing a positive electrode which includes forming a solid electrolyte by mixing a lithium salt and a polymer for a solid electrolyte in a dry atmosphere, forming a dry mixture by stirring after adding a conductive agent and a positive electrode active material to the solid electrolyte in a dry atmosphere, and pressing after coating a current collector with the dry mixture.
Claims9
A method of preparing a positive electrode, the method comprising:
- mixing a lithium salt and a polymer in a dry atmosphere to form a solid electrolyte which is in a solid state;
- forming a dry mixture by stirring after adding a conductive agent and a positive electrode active material to the solid electrolyte in a dry atmosphere;
- and
- pressing after coating a current collector with the dry mixture,
- wherein the dry mixture comprises granules formed by coagulation of the solid electrolyte, the positive electrode active material, and the conductive agent.
