HAPSMobile and APB reach basic agreement to develop storage batteries for HAPS using All Polymer Battery
Sanyo Chemical Industries, Ltd.
announced today its affiliate; APB Corporation (“APB”) and a subsidiary of SoftBank Corp.; HAPSMobile Inc. (“HAPSMobile”)
have reached a basic agreement to collaborate on the development of high energy density storage batteries for the High Altitude Platform Station (HAPS) stratospheric telecommunications platform being developed by HAPSMobile.
HAPS is a stratospheric telecommunications platform
that can provide mobile Internet connectivity, such as LTE and 5G, from the stratosphere to areas without Internet access.
For its HAPS business, HAPSMobile
is developing the “Sunglider” unmanned aircraft, which will 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.
To achieve high quality batteries, a bipolar structure
has been developed where the current flows through the cellular interfaces perpendicular to the electrode plane.
The electrode material of All Polymer Battery is wrapped with gel-like polymer containing an electrolytic solution.
With the adoption of such technologies, All Polymer Battery
is characterized by such features as high reliability, high energy density, and innovative manufacturing processes at the same time.
With few parts required, thanks to bipolar structure and polymer-based constituent material, All Polymer Battery
has high flexibility in size and shape of the cells, which will help us to create thicker electrodes and larger cells.
HAPSMobile and APB
believe that All Polymer Battery may be able to support Sunglider’s long stratospheric flight times due to its high energy density and high reliability.
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
