SoftBank Group Corp.¡¯s telecoms arm is considering using battery technology from Japanese startup 3DOM Inc. as the investment giant pushes further into wireless communications projects that use flying devices, according to the battery-maker.

3DOM¡¯s technology will likely be used for future mobility applications that require high-battery capacity, such as flying taxis or drones, 3DOM Vice President Shusuke Oguro said.

3DOM is working on lithium-metal batteries, which are more energy dense and charge much faster than lithium-ion batteries. Last month the seven-year-old firm announced plans to list in Singapore via a reverse takeover of restaurant operator Chaswood Resources Holdings Ltd.
