ABSTRACT:
Disclosed is an electrode slurry comprising: (a) an electrode active material capable of lithium intercalation/deintercalation; and (b) monomers capable of forming a polymer via polymerization. An electrode having a binder polymer formed by applying the electrode slurry onto a current collector and carrying out in situ polymerization of the monomers, and an electrochemical device comprising the electrode are also disclosed. The electrode uses monomers capable of forming a binder polymer via polymerization under heat or light upon drying of the electrode, instead of the conventional PVdF or SBR-based binders. Therefore, it is possible to simplify a process for manufacturing an electrode, to provide an eco-friendly electrode by virtue of the use of an aqueous solvent as a dispersion medium, to improve the ion conductivity of a binder by virtue of the use of a solvent for a battery electrolyte as a dispersion medium, and thus to improve the quality of an electrochemical device.
