Submarines use batteries for quiet propulsion underwater.
Until recently, submarines used lead acid batteries, which were heavy and less energy efficient.
The adoption of lithium ion batteries is a huge improvement over the older batteries but carries some risks.
Japan’s submarine fleet is getting a major upgrade, and it’s likely the same tech found in the device you’re using to read this article. The new submarine Toryu, or “Fighting Dragon,†is equipped with lithium ion batteries, which power most of the consumer technology available worldwide. The result is submarines capable of cruising silently underwater longer than ever.
