Dry Electrode for Electrochemical Device and Method for Manufacturing the Same

A dry electrode for an electrochemical device includes a dry electrode film as an electrode active material layer. The electrode active material layer includes an electrode active material and a binder resin. The binder resin is fibrillated. The electrode active material layer has an average pore diameter of 5.0 μm or more and a porosity of from 15 vol % to 50 vol %, wherein the average pore diameter is calculated based on a longest pore diameter. The large pore diameter of the electrode active material leads to easy lithium (Li) migration, low Li diffusion resistance and fast lithium movement, thereby reducing or suppressing overvoltage, and improving high rate charge/discharge characteristics. Also provided is a method of manufacturing a dry electrode film.
