HAPSMobile, APB Collaborate to Develop High Energy Density Storage Batteries

Tokyo-headquartered HAPSMobile and APB Corporation (APB) have collaborated to develop high energy density storage batteries for the High Altitude Platform Station (HAPS) stratospheric telecommunications platform being developed by HAPSMobile.

APB Corporation was founded in 2018, and its business area includes R&D, production and sales of lithium ion batteries.

HAPS platform provides mobile Internet connectivity, such as LTE and 5G, from the stratosphere to areas without Internet access. For its HAPS business, HAPSMobile has been developing the ‘Sunglider’ unmanned aircraft, which is going to be equipped with a large capacity and lightweight storage battery to provide long-term service.

All Polymer Battery, the first large-scale bipolar lithium-ion battery module, has been developed jointly by Hideaki Horie, the current CEO of APB, and Sanyo Chemical.

All Polymer Battery is characterized by features such as high reliability, high energy density, and innovative manufacturing processes at the same time. These batteries have high flexibility in size and shape of the cells, which will help us to create thicker electrodes and larger cells.

By taking advantage of the bipolar structure of All Polymer Battery, both companies will endeavor to eliminate wiring parts necessary for high voltage, increase the ratio of polymer in the components, and adopt next-generation electrode materials that contribute to high energy density with high reliability.

HAPSMobile, founded in 2017, is into research, development, operation and management of solar HAPS and network devices; Core network building, management and operation; Acquisition of frequency for solar HAPS; and Business development using solar HAPS.
