SoftBank bets on battery building to back bit barns
"It hopes to begin mass production in financial year 2027, and expects the operation to generate revenue of ¥100 billion (over $600 million) per year by 2030. SoftBank is working with two South Korean firms that have a track record in advanced battery-related technologies. One is Cosmos Lab, developer of zinc-halogen batteries that use pure water as an electrolyte, making them non-flammable, and the other is DeltaX, which designs and manufactures battery-based energy storage systems (BESS)."
"Reg readers may recall that SoftBank last year bought the rights to a former Sharp LCD panel factory in Sakai City, Osaka prefecture in Japan, and said it planned to convert it into a datacenter to operate AI agents developed jointly with ChatGPT creator OpenAI. The site will now become an industrial cluster, home to its battery manufacturing facility as well. SoftBank referred to it as a core hub to establish its AX Factory (a center for datacenter operations and AI infrastructure hardware manufacturing), and GX Factory (serving as a manufacturing facility for next-gen batteries, solar panels, and related products)."
SoftBank is entering the datacenter battery business and plans to manufacture battery systems at gigawatt-hour-per-year scale to meet power needs for AI infrastructure, including its own facilities. The company intends to deploy the systems first at its large-scale AI server farms, then make them more widely available in the future. Mass production is targeted for financial year 2027, with expected revenue of ¥100 billion per year by 2030. SoftBank is working with South Korean firms, including Cosmos Lab, which develops zinc-halogen batteries using pure water as an electrolyte for non-flammability, and DeltaX, which designs and manufactures battery-based energy storage systems. The manufacturing facility will be located at a converted industrial cluster tied to SoftBank’s AX Factory and GX Factory plans.
