Japan roars ahead with Li-ion batteries

7th March 2020 - 02:00 GMT | by Gordon Arthur in Christchurch


The Japan Maritime Self-Defense Force (JMSDF) commissioned its first lithium-ion (Li-ion) battery-powered submarine on 5 March. 

This makes Japan the first nation in the world to adopt this type of battery in a conventional SSK.

The 2,950t JS Oryu (SS 511) was inducted in a ceremony in Hyogo Prefecture. The vessel will be assigned to Submarine Flotilla 1 based in Kure.

The 84m-long boat was built by Mitsubishi Heavy Industries (MHI) in Kobe, and it is the eleventh Soryu-class submarine to enter the JMSDF. JS Oryu was laid down in March 2015 and launched in October 2018.
