    Ok, so the Japanese are just substituting better batteries for a Sterling engine; but my gut tells me this could be a huge development in conventional submarine technology. Just imagine the market/performance possibilities raised by swapping lead-acid for lithium in other diesel boats!

    Would Litium-ion batteries be more expensive than the traditional AIPs? Not that is matters if it is just a little bit more expensive. I guess Lithium-ion battery makers will make a lot of profit, not the AIP makers.

    I'd have expected you to be more pleased. Ditching traditional AIP technology for lithium-ion power simplifies the powertrain for high-performance SSKs, likely reducing costs. It also adds the prospect of relatively cheap retrofits to older boats.

    Japan is pioneering this idea with subs, so yes, I would certainly give them credit. You are correct about the simplified powertrain. I didn't think about that.

    its a good move, the use of LI ion battery is cheaper, easily available and more safer. and yo don't have to get air independence in such sources.

    Safer ? Maybe, we do not know for sure, yet.
