    Abstract: A manufacturing method of a secondary battery is provided to improve a manufacturing efficiency of a non-rectangular electrode. The manufacturing method is provided for a secondary battery and includes forming the non-rectangular electrode. The step of forming the electrode includes, prior to forming an electrode precursor by applying an electrode material layer raw material to a metal sheet material that becomes a current collector, controlling a wettability of a local portion of a surface of the metal sheet material to the electrode material layer raw material and forming a wettability control region in the local portion. The local portion becomes a cutaway region of the non-rectangular electrode.

The electric load is connected to the power supplying mechanism by the power line. The storage pack is connected to the power line. The charging/discharging curve of the storage pack has a step difference that passes through the rated voltage of the power supplying mechanism. An average discharging voltage on a lower-SOC side of the start point of the step difference is ?20% or more of the rated voltage. An average charging voltage on a higher-SOC side of the end point of the step difference is +20% or less of the rated voltage.
