Materials that do not react with chemical substances are required for stable storage of chemical energy. Therefore, surface treatment of stainless steel is performed using nitrogen heat treatment and sputtering. Evaluate corrosion resistance by electrochemical measurement and use various analytical instruments to search for optimal conditions for surface treatment. Due to the high stabilization of stainless steel, it is expected to be used for stable storage of energy, specifically for current collector materials of lithium-ion cells and bipolar plates for polymer electrolyte fuel cells.
