Das japanische Unternehmen „SoftBank Corp.“ hat die Entwicklung eines Batteriepacks für den Einsatz in Höhenplattformen für die kabellose Kommunikation bekanntgegeben. Das Pack enthalte Lithium-Metall-Batteriezellen des Herstellers „Enpower Japan“ mit einer spezifischen Energie von 439 Wattstunden pro Kilogramm. Anfang 2023 hatte SoftBank zusammen mit der Tochtergesellschaft HAPSMobile einen Zyklustest des Akkupacks in der Stratosphäre vorgenommen.

SoftBank Corp. develops battery pack with Enpower Greentech's next-generation battery cells and successfully demonstrates operation in the stratosphere.

Enpower Greentech Inc. has successfully developed a 4095mAh cylindrical battery, delivering industry leading energy densities of 389Wh/kg and 888Wh/L. This development has resulted in a new energy density record in the class of rechargeable 18650 cylindrical batteries.

Enpower Greentech Inc. has successfully developed a 100Ah lithium metal battery (LMB), another major step in the commercialization of next-generation batteries for electric vehicles.

Enpower Greentech Inc. (the holding company of Enpower companies in the US, Japan and China) has raised $20 million in a Series-A+ round led by Sequoia China and Dayone Capital. GAC Capital, BR Capital, Tianqi Capital and Niuli Venture also participated in the financing round. Scheme Capital served as the financial advisor.

Enpower Greentech’s lithium metal battery (LMB) has passed the nail-penetration test, which is a very challenging safety test for lithium-ion batteries. Enpower also obtained the UN38.3 transport safety certification from an accredited third-party tester.
