A new kind of resin-based battery developed in Japan moved a step closer to a real-world debut -- in a robot submarine.
Kawasaki Heavy Industries Ltd. is testing an autonomous underwater vehicle powered by an all-polymer battery made by APB Corp., the battery maker said in a statement on Monday. The Japanese industrial giant plans to commercialize the sub, which measures about 3 meters (10 feet) in length and weighs 7 tons, for use in subsea pipeline inspection by March 2022.
