Title: Japan proposes building lithium ion battery-power
Post by easel on Oct 6^th, 2015 at 7:38pm

Quote:

A Japanese team seeking to win a bid to build Australia's submarine fleet said Tuesday it plans to construct the vessels in Australia and proposed jointly developing the world's first lithium ion battery-powered sub.

Representatives of the Japanese government and Mitsubishi Heavy Industries Ltd. made the remarks at a briefing session for the local defense industry held during a three-day international maritime exposition which got under way in Sydney on Tuesday.

The team, which is competing for the project with French and German companies, said it plans to train Australian engineers before the actual construction begins and transfer Japan's submarine technologies.

Then how would it be a Soryu class submarine? Does this mean they are not offering the Japanese submarine anymore? Is this a joke? Is lithium an appropriate battery source for major machinery? Apparently it has issues with storage.

If I google lithium I get bipolar.

Japan is hoping Australia will chose a variant of its 4,000-ton Soryu submarine for one of the world’s most lucrative defense contracts. It played up the high-capacity lithium ion battery, the world’s first, as well as the stealth technology that they said they would be happy to share with Canberra despite concerns over espionage, particularly from Beijing.

apan has decided to power its new batch of Soryu-class submarines with Lithium-ion batteries instead of air-independent propulsion (AIP) technology — a move that could raise eyebrows after similar types batteries were faulted for fires aboard the Boeing 787 Dreamliner.

Yasushi Kojima, a spokesman for the Maritime Self-Defense Force (MSDF), said the change would affect the next four remaining Soryu-class submarines in Japan’s 10-boat class.

All I can find is that there is one submarine they haven't built yet they are proposing to develop these batteries in.

If this goes ahead, it appears that the single submarine will be a test vehicle. The battery type will have no impact on endurance, performance, silence or detectablity.

They are proposing to have the entire Australian submarine fleet experimental.

Either that or they are spreading disinformation to protect top secret technology.

That has nothing to do with the thread.

To continue the topic:

Australia has a navy fleet of about 5 capable warships. China has hundreds. In a war, they would expect to lose at least a third before the second stage of the war, due to modern warfare and all that.

Australia has a navy that is not war capable.

And now it appears as though Australia is being touted as a source for military experimentation. It has no other purpose.

The publicly available information states Japan will build one submarine with this battery design and the rest will have tried and tested technology. That would imply that the single submarine will be an experimental test vehicle. They are further proposing to have the entire Australian submarine fleet as a Japanese military experiment utilising untested technology, if that rationale is followed.

these are sanctions that can get worse

So the Australian submarine will not actually be a Japanese Soryu design if Australia goes with a Japanese option.

It will also not be a French Barracuda submarine if Australia goes with the French option. It will be a Shortfin Barracuda.

This is also neglecting that, regardless of what it looks like, internally it will not have the same systems as what either the French or Japanese are using themselves.

Australia is getting shortchanged.

Reuters reported in September that Australia was leaning towards buying 12 submarines based on Soryu-class vessels built by Mitsubishi Heavy Industries and Kawasaki Heavy Industries. The new submarines will replace six ageing Collins-class boats.

In talks since then, Canberra has said it wants a lithium-ion battery propulsion system for the submarines, two Japanese officials and one Australian official told Reuters.

If Australia buys 12 submarines with this technology they will be the only country in the world to do so.

And the Australian submarine fleet will be an experiment to provide data for r&d for the rest of the allied worlds submarine development projects.

They are being offered AIP though.
