AI-summarised brief · reviewed before publication
Softbank Corporation has launched a battery cell and battery energy storage system manufacturing business in Japan, aiming to produce non-lithium battery cells based on zinc-bromine chemistry. The company plans to achieve GWh-scale mass production by around FY2028 and integrate cells into containerised BESS enclosures. Softbank has partnered with startup COSMOS LAB to develop the cells, which use water electrolyte and are designed to be highly safe and non-flammable. The move is part of a play to capitalise on growing demand for AI data centres and new energy infrastructure, with Softbank aiming for annual revenue exceeding JPY100 billion by FY2030. Two new facilities will be built in Osaka to support the business.
