YUKI MURAKAMI, Nikkei staff writerJuly 21, 2020 00:29 JST KYOTO -- Sanyo Chemical Industries' rechargeable battery made almost entirely of plastic is now powering an unmanned submarine by Kawasaki Heavy Industries in a test run, with the promise of doubling the vehicle's operation range to 16 hours. The trial presents the first commercial use of the all-polymer device made by Sanyo subsidiary APB. The battery, whose electrolytes are also made of resin, lasts twice as long as its lithium-ion cousin and boasts cheaper production costs and greater resistance to fires. Kawasaki's autonomous underwater vehicle is designed to inspect oil pipelines and other deep sea equipment. Due to the nature of the work, an internal battery would be subjected to high pressures. The all-polymer battery can withstand depths of more than 3,000 meters. APB's battery can power the vehicle for about 16 hours on a single charge, up from roughly eight for a lithium-ion battery. Mass production for the all-polymer battery is said to cost 90% less than for a lithium-ion counterpart due to the simplicity of the manufacturing process. APB, is setting up a plant in Japan's Fukui Prefecture. Full-scale production will be ready around fall 2021, with sales to begin before the fiscal year ends in March 2022. The aim is to develop a business worth hundreds of billions of yen (100 billion yen equals $934 million) within five to 10 years. The operation will focus on stationary power storage for buildings, but batteries for undersea drones have become feasible as well. APB has raised roughly 9 billion yen from eight investors through June, including trading house Toyota Tsusho and energy major Eneos Holdings. Both Nissan Motor and Sanyo have licensed polymer battery technology to APB to accelerate development. 1 Link to comment Share on other sites More sharing options...
meng.huat Posted July 26, 2020 Share Posted July 26, 2020 battery powered sub can be easily mod into a very dangerous weapon of mass destruction. battery powered, no engine. "silent" operation, difficult to detect by sonar or other radar. just load the sub with a nuke and launch it as a self driving torpedo. 1 Link to comment Share on other sites More sharing options...

They use ambient noise from other ships, marine life to mask their presence. 1 Link to comment Share on other sites More sharing options...
