“Production of parts of special battery-cell for civil aircrafts and space use”
Shimamoto Factory


Our company’s history has been that of manufacturing battery components. Over the past 45 years, as battery components have evolved, we have accumulated the technologies necessary to manufacture them in our company. We combine these technologies, skilled people, and equipment to manufacture excellent battery components.


We manufacture almost all components used for specialized battery, from the cases and lids used for battery cells to the processing of electrodes and separators used inside the cells, busbars and bolts that connect the cells, and the assembly of battery unit boxes and connectors.
