SoftBank announced plans to enter the energy storage market, aiming to start manufacturing battery cells and storage systems in fiscal 2027 (before March 2028) and reach gigawatt-scale annual capacity in fiscal 2028. The company will partner with South Korea’s Cosmos Lab to develop zinc-halide batteries using a water-based electrolyte—promoted as less prone to catching fire—and with DeltaX to design large-capacity energy storage systems. This move diversifies SoftBank’s portfolio into grid-scale storage and targets safer battery chemistries, relevant for renewable integration and utility-scale deployments. The partnerships signal a strategic push into hardware manufacturing and battery innovation ahead of growing demand for reliable, non-flammable storage.
Min-Jeong Lee / Bloomberg : SoftBank partners with South Korea's Cosmos Lab and DeltaX to mass produce next-gen data center batteries in Japan at the scale of one GWh per year in FY 2027 — SoftBank Group Corp.'s mobile unit said it plans to begin large-scale battery cell manufacturing at its Sakai, Osaka plant to address growing power demand for AI services.
