Core offering

I.D.F (Ishinomaki Dream Factory) manufactures and sells laminated manganese lithium-ion battery cells, custom-size cells, modules, and packs using technology developed at Tohoku University Future Science and Technology Collaborative Research Center. The batteries feature low internal resistance for superior cold-weather and overcast-condition performance, particularly when paired with solar panels. The company also sells downstream battery application products including solar LED lighting (まいてらす), a 4.8kWh residential/commercial energy storage system (うごたま), a cloud-based water measurement system, and floating rescue stations (FRS).
