Abstract
A conductive agent having a nonzero surface charge, a positive electrode slurry composition of a lithium secondary battery, including the conductive agent, and a lithium secondary battery including the conductive agent.
Claims9
A positive electrode slurry composition comprising:
- a positive electrode active material, a conductive agent, a dispersing agent, and a solvent, wherein the conductive agent has a nonzero surface charge;
- wherein the particles of the conductive agent are surface-treated by the dispersing agent, and the dispersing agent contains an aryl-based main chain containing a fluorine group at the end of the main chain, and has a molecular weight from about 100 to about 100,000 g/mol.
