Abstract
Disclosed is an electrode, comprising a coating layer of crosslinked polymer, formed on a surface of electrode active material particles, while maintaining a pore structure formed among the electrode active material particles interconnected to each other in the electrode. A method for manufacturing the electrode and an electrochemical device comprising the electrode are also disclosed. The electrode, which comprises a coating layer of crosslinked polymer formed on the surface of the electrode active material particles, can improve the safety of a battery, while minimizing degradation in the quality of a battery.
