SoftBank to begin large-scale battery cell manufacturing at Osaka plant starting next April, partnering with South Korea's Cosmos Lab and DeltaX

SoftBank Corp. will partner with South Korea's Cosmos Lab and DeltaX to enable mass production of large-scale battery cells from the fiscal year starting next April at its plant in Sakai, Osaka Prefecture.

The facility aims to output energy storage systems at a scale of one gigawatt-hour per year, which would make it one of the largest facilities in Japan. SoftBank could scale up to a capacity of several GWh.

The batteries will be used to help power AI data centers that SoftBank is developing, and the company also plans to provide them for grid applications, factories, and other industrial and residential uses. Over the medium term, SoftBank will look to expand into global markets.
