Japan Goes Back To The Future With Lithium-Ion Battery Powered Submarines

For nearly a century, diesel-electric submarines relied on constantly charging traditional lead-acid batteries by running their diesel engines either on the surface or later on, while snorkeling near the surface. This left them constantly vulnerable, as they could only hide deep beneath the surface for hours or a couple days at a time. Over the last few decades, Air Independent Propulsion (AIP) technology has revolutionized the traditional diesel-electric submarine  Performance capabilities approaching the the domain of highly expensive and large nuclear submarines have became available for a fraction of the cost in the form of smaller, AIP equipped diesel-electric submarines. Now the diesel-electric submarine is on the verge of yet another revolution, one that will return to type to its original roots, relying on diesel engines and batteries alone to go about its clandestine business.

Until the battery combusts.

Until the battery combusts.

It depends on how the battery is constructed. The combustion in cheap or old made Lithium battery is because molecules of the LiCo2 begin to attach themselves to the cathode in the battery, eventually, enough of the molecules have detached from the Li anode and attach to the cathode, that it creates a short, and combustion.

Some of the newer Li batteries have changed the design with a ceramic separation layer that allows the electrons to move freely but prevents the Li molecules from getting to the cathode.
