ELECTRODE FOR Li SECONDARY BATTERY, METHOD OF PRODUCING THE SAME AND Li SECONDARY BATTERY

摘要

PURPOSE: An electrode for lithium secondary battery is provided to reduce a cataclastic phenomenon even while having high capacity by inducing the activation of lithium oxide generated during an electrochemical reaction. CONSTITUTION: An electrode for lithium secondary battery comprises metal nanofiber of a network structure, and a metal thin film or metal oxide thin film which contains the metal nanofiber. A manufacturing method of the electrode comprises: a step of preparing a metal-precursor-containing polymer solution; a step of forming a metal/polymer nanofiber by electrospinning the polymer solution on a substrate; a step of forming a metal oxide nanofiber by heat-treating the metal/polymer nanofiber; a step of forming a metal nanofiber during reduction of the metal oxide nanofiber; and a step of forming a metal thin film or metal oxide thin film on the substrate.
