BATTERY ELECTRODE MANUFACTURING METHOD AND BATTERY MANUFACTURING METHOD

摘要

PURPOSE: A manufacturing method of an electrode for a battery is provided to manufacture an electrode for a battery with a plurality of stripe active material patterns, thereby improving the capacity and charging and discharging capacity of a battery. CONSTITUTION: A manufacturing method of an electrode for a battery comprises a step of moving a nozzle(21) to a specific injection direction, spreading an active material-containing liquid to a substrate with a stripe shape to form a first active material pattern(221); a step of moving the nozzle to the injection direction, spreading the active material-containing liquid to the substrate with a stripe shape to form a second active material pattern. The starting point of the first active material pattern and the starting point of the second active material pattern are different to each other in the injection direction.
