Abstract: When 3DF is used as an active material paste application method for a universal metallic foil, air remains in the 3DF to reduce the stability of electrode characteristics and a micro short circuit might occur in a battery due to the 3DF exposed to the inside and outside of the electrode or metallic microparticles attached to the 3DF. In the following manner, active material powder paste application to the 3DF is divided into two steps to resolve the above-described problem. In the first step, 3DF pastes are put to one surface for simultaneous air removal and paste charging (first-stage application process). In the second step, new paste is applied to a surface of the electric electrode obtained in the first step (second-stage application process). The electrode obtained in the second-stage application process has little remaining air and is capable of uniformly holding metallic powder or the 3DF itself in the electrode (first-stage application process). In addition, Li ions can freely move between the surface of the electrode and a core portion through an opening portion provided at tips of multiple protruding portions of the 3DF, and thus the micro short circuit of the battery can be prevented by Li dendrite even after repeated charging and discharging.
