Abstract
A method for manufacturing an electrode may include (S1) preparing a sol solution containing a metal alkoxide compound, and (S2) forming a porous non-woven coating layer of an inorganic fiber by electroemitting the sol solution onto an outer surface of an electrode active material layer formed on at least one surface of a current collector. The porous non-woven coating layer formed on the outer surface of the electrode active material layer may be made from an inorganic fiber having excellent thermal stability. When an electrochemical device is overheated, the porous non-woven coating layer may contribute to suppression of a short circuit between a cathode and an anode and performance improvement of an electrochemical device due to uniform distribution of pores.
