In order to promote energy conservation and renewable energies, which have seen a sudden increase in popularity since the Great East Japan Earthquake, there is an indispensable need for storage devices that can capture such energy. Among such devices, next-generation lithium-ion batteries possess high energy density and can be reused many times. They are widely used as small storage devices ranging from small-scale dispersed power sources to batteries for electric vehicles and mobile phones, with further applications continuing to be researched and developed. However, it is not easy to purchase small-scale production line batteries for use in research or at the starting stages of businesses. This poses barriers to research and development, new market entries, and the founding of start-up firms.


This technology makes it possible to supply 50 to 1,000 mAh next-generation laminated lithium-ion batteries. The laminated cells are constructed under laboratory conditions within a dry-air environment (supplied air – dew point at <-95 Celsius, room dew point when non-operational at -70 Celsius). By making use of superior assembly devices and knowledge about next-generation lithium-ion battery development cultivated in a laboratory, it is possible to provide stable cells. In addition, as research-use cells, it is possible to disclose internal samples, and it is possible to provide cells on a custom order basis using any type of material and with the characteristics the recipient desires. 


Based on this technology, it is possible to supply a variety of next-generation lithium-ion cells with varying capacities and characteristics according to the recipient’s desires and conditions. 


As small-scale next-generation lithium ion-cell batteries for research use, it is possible to disclose internal samples and it is possible to provide cells on a custom order basis using any type of material and with the characteristics the recipient desires.
