The first in the world: the Japanese launched the submarine with lithium-ion batteries

Last week, the Kobe Mitsubishi Heavy Industries shipyard held a solemn launching ceremony of the world's first non-nuclear Oryu submarine equipped with lithium-ion batteries, reports bmpd.


The first in the world: the Japanese launched the submarine with lithium-ion batteries


This will allow Japanese shipbuilders to abandon the use on submarines not only traditional lead-acid batteries, but also on air-independent Stirling engines.

Oryu became the 11-th in a series of submarines of the type Soryu. Its length is 84 meters, displacement is 2950 tons, maximum speed is 20 knots. Laid in November 2015. A transfer to the Japanese Navy is scheduled for 2020 year.



According to the resource, lithium-ion batteries give submarines the duration of the underwater stroke, comparable to the duration when using air-independent installations (VNEU). At the same time, unlike VNEU, the supply of energy in lithium-ion batteries can be constantly replenished using the RDP device.

In addition, lithium-ion batteries, compared with lead-acid, have a much longer service life and do not require maintenance.

The disadvantages include the high cost of new batteries - the contract value of the eleventh Soryu submarine was about $ 556 million versus $ 454 million of the previous boat of this type. The difference in 112 of millions is given just by lithium-ion batteries.

      Along the way, we are all stuck on lithium-ion batteries, Imha people will make a leap forward when they come up with a new type of battery, more compact and energy-intensive.
      The difference in 112 million give just lithium-ion batteries.

      Imha. The difference is not 112 million but even more. We must also throw out the cost of lead-acid batteries and Stirling's non-volatile engines.
      There probably all 200 million worth of batteries.

        This fee is not so much for the batteries as for the possibility of a long autonomous course, i.e. for the new quality. Estimate what the lead batteries with a double energy reserve would cost and if the boat would not drown with them. Lithium batteries have up to 200 Wh / kg, and lead batteries have 30. So this is also an additional place on the boat, which is always in short supply.

          Donetsk.
          Once upon a time - a couple of years ago I read about an American company that at one time was engaged in industrial lithium-ion batteries, but began to endure bankruptcy and it was bought by one "Russian businessman," Putin's friend "" ... I began to wait when on Russian submarines will have just such batteries so as not to bother about expensive Stirling engines ... But so far they have only appeared on electric buses ... for now ... or already? I really hope that they will be on the new air-independent boats. And on ordinary diesel engines, equalizing their combat capabilities with any air-independent and enemy nuclear submarines. If we had our own lithium for the batteries, the cost of our batteries would be noticeably lower than the Japanese one, and the combat capabilities of the new Varshavyankas would acquire a truly strategic character (taking into account their special design CD weapons).

            I believe that control and maintenance of "maintenance-free" LI batteries can be more expensive than nuclear power plants.

              ---------------------------
              Li-on seems to be temperature-dependent, the charge decreases faster at low temperatures. Yes, and even degrade during storage, that is, after a year or two they will require replacement. Many advantages, but many of their shortcomings. And in general, do they just have lithium-ion or already lithium-propylene (Li-Pol)?

        Those. the cost will double. And about half a billion dollars Yasen-M will cost us, so here we can’t even compare, though noisier, but it pounds from a distance, which doesn’t matter, the speed is an order of magnitude, etc. Well, Poseidon’s nuclear weapons, the insider tells us that quiet, and the super torpedo lies on the ground and waits for three years on duty, then returns to the service. YaSU is the best VNEU, and if it is compact, and even low noise, then there is no alternative to it and the same batteries are not the best option in this life and take up a lot of space and, by the way, are also highly explosive and fire hazardous, contain aggressive substances, etc.

          For some reason, it seems that the best option is a low-power, small-sized, low-noise YaSU, working on battery charging. Then the battery can be charged without surfacing under the RPD, to the delight of anti-submariners, but rather going to an ambush depth.

          Well, you can’t be so reckless!
          1. ABs with silicon anodes instead of graphite (Yu.Kaliforniansky un-t) have 3 times greater capacity than Li-I.
          2. ABs with porous carbon nanowires with electrolytic additives (Stanford University) and a nano-coated anode - have 5 times higher capacitance than Li-I.
          3. ABs with an anode of tin (Washington University) - have 3 times greater capacity than Li-I.
          And such examples up to 17 pieces.
          But the most impressive is Fuji Pigment's Al-air AB (Alfa battelj) has 40 (!) times more capacity, than Li-I. Moreover, the recharge is topping up water, possibly even salty!
          Therefore, there will still be something to be surprised. Aha

      The Japanese lost the war, and therefore work. By the difference of 112 cartoons, it was also tricky, it’s not only the difference between new batteries in comparison with acid batteries, but also the power plant and cryo equipment are also worth a lot of money, so the difference in the cost of the batteries themselves will be even greater. Also, there is no operational experience, if it does not explode for a long time then it will be possible to judge.

        Lead is safe in open ventilated volumes and the more volume and ventilation the better — in closed vapors, acid is not good, but especially on pl. So with a car you do not need to compare, it was nearby and with the battery shop too.

        What nonsense? We compared the polyethylene shell of the household with the battery case on the submarine. So lead with leaked electrolyte will also die.
        Modern lithium ones have long been relieved of the shortcomings of the first samples - lithium is not formed there in a metallic form (because of which there were fires), only ions. The charge-discharge algorithm is more serious - that's how two buckets of "smart" electronics were invented for this.
        specific characteristics of lithium-ion acc: 100-180 Wh / kg and 250-400 Wh / l 360-648 kJ / kg
        It is taken into account that 1 kg of oxygen per 3 kg of kerosene. If you count kerosene + oxygen, and taking into account Stirling's efficiency of 30%, Kerosene 43500 kJ / kg 43500 / 4.18 = 10287 - stirling efficiency 30% - 3 429 kJ / kg
        Stirling is, in principle, 5 times better, but the weight of the engine, cryogenic installations and the fact that you cannot replenish oxygen during the campaign, and the hassle with it at the bases is an expected solution. Return to a conventional diesel-electric boat, which can crawl at low speed 5 times longer than a lead boat. No more.

The electric car crashed into a concrete splitter at high speed, after which it collided with two more cars.

During the conversation (question-answer), he said that although the boat itself is not in the construction plans, VNEU successfully passed bench tests for it. About the type of VNEU did not split, but said that it was different from the Western ones and better than them. I don't know, I didn't force him to lie.

      For me, VNEU is a dead end, and even the Germans have how many of these boats, 5 definitely do not come out of the repair. In general, l-and batteries, especially on a boat, are a dangerous thing, hydrogen too. For napl, this is still a big problem, replacing diesel engines. Moreover, ours are not copying the Stirling scheme, but they are developing their own, better longer, but better. Although, again, this is a way to a dead end in my opinion. Yes, and lithium batteries should be disposed of as needed, but nobody knows how it would be cheaper than the batteries themselves.

The ideal described in the books of our science fiction writers is the ability to charge using your position in the depths, without ICE, without liquid oxygen (hello VNEU).

      Varshavyanka will be the basis of the KTOF submarine forces. Due to problems with the construction of the 855M project and the inability to repair the 971A project, the only linear MAPL 971A project remained at the KTOF.

      Liotech, Chubais's brainchild, is not enough for you? To build a plant, you first need to develop Li-Ion-accumulators and batteries, develop technology, equipment, organize the production of materials - but there have been no serious investments in HIT since the times of the USSR. Once we were leaders in both primary and secondary lithium HPS, both thermal and fuel, and now the industry is where our legs grow. Lagged behind forever.

        Here the question is, how to dispose of them? At the same time, at a price lower than the battery itself, eh? L-also not a panacea, but most likely a dead end branch. So, in this regard, the stupor is still technological, and it may not be in vain that they refused at one time. But radiochemical batteries are a promising issue.

      "The world's largest" plant "Liotech" in Novosibirsk, to which "Rusnano" invested 7.5 billion rubles. was opened in 2011. And "successfully went bankrupt" in 2015.
      The total investment is 14.8 billion rubles.
      An innovative enterprise was created as a joint venture Rusnano and the Chinese Thunder Sky Group.
      Creditors of the bankrupt Novosibirsk plant Liotech (LLC Energy Solutions) plan to conclude a settlement agreement. Previously it was planned that a new enterprise would be created on the basis of the plant, where a part of Liotech's production assets would be withdrawn. The remaining assets, as well as the shares of the new company, were supposed to be sold and thus settled with the debts of the plant.
      The bankruptcy manager of the plant, Yulia Trofimova, noted that the company plans to profit from production activities and rental of premises.

      In 2017, Liotech plant mastered the production of a new type of product - lithium-ion traction batteries for electric loading equipment.
      In 2018, the company plans to release more than 200 car kits on lithium-ion batteries.

      In 2016, a plant was opened in Grozny (Chechen Republic)
      The first phase of the Russian-Korean plant for the production of innovative lithium batteries opened in Grozny. The project was implemented on the basis of Chechenneftekhimprom JSC together with the Korean company KOKAM. With the launch of the enterprise, 70 jobs were created. The staff was trained in South Korea.
      The project consists of two stages with a total cost of 7,6 billion rubles.

    Japanese Shipbuilder Mitsubishi Heavy Industries (MHI) launched an 11th-class submarine Soryu for Japanese naval self-defense forces at its Kobe shipyard.
    JS Oryu (SS-511) was launched on October 4 and is the first JMSDF submarine powered by lithium-ion batteries that store significantly more energy than the lead-acid batteries installed on the previous ten Soryu class submarines.
    Oryu is the sixth class boat built by MHI. Another shipbuilder involved in the construction of Japanese diesel-electric submarines is Kawasaki Heavy Industries, which launched the tenth submarine in November 2017.
    Soryu are also Japan's first submarines equipped with non-volatile propulsion systems that allow them to remain submerged for longer.
    2950-ton submarines are driven by a diesel-electric engine to a maximum declared speed of 20 knots. Crew 65 people
    Japan has commissioned 9 units in the class so far, while a total of 13 are planned to be operational by 2023.

      At the same time, the Japanese returned to the roots

      Japas replaced conventional zinc-acid with lithium-ion batteries. 3-4 times increased battery capacity, but from this boat did not stop diving. Charging through 10-15 days under the RPD also unmasks the boat, as with conventional batteries. But, if Stirling will rotate the EG in the underwater position, then it will only be necessary to float to ventilate the compartments through the end or through the same RDP device. In addition, electric propulsion is by far the most low-noise diving method, even for nuclear powered ships. By the way, in order to reduce the unmasking signs of whether the PLO will also be transferred to electric propulsion, especially in areas of search for submarines. Such developments are available.
      Therefore, it’s too early to panic. Let's see how our Kulibins will be born. Reforming diesel fuel and a single GED is a promising business for our nuclear submarines.
      IMHO.

    There are proposals for diesel, nuclear, lithium-ion and VNEU installations, all of the listed installations (all have data) are being built by all states who have "experience". Do not be fooled (sorry) from a submarine with the duration of its stay under water. Russia has gone a lot far (thanks to our designers) - and now - diesel fuel - atom - vnutryanka !? - I do not think that it will not, will not be in the near future, plasma is used (in the circumference of the object), well, and the main thing for which science is striving is to control objects using gravity (maybe not even from the ground). I saw it sober - not alone (do not use at all) - Chelyabinsk region. - not far from the city of Chebarkul (during night shooting - in winter).

    In addition, lithium-ion batteries, compared with lead-acid, have a much longer service life and do not require maintenance.


    It is good if these lithium-ion batteries do not swell during operation. Apparently the Japanese have already eliminated these shortcomings since they are building submarines with these batteries.

      Exactly, especially when you read "Pallas Frigate". In 1853, they were in feudal Japan, where they went to the backward ship and everything was a wonder to them, and in 1905 they shook them off to the fullest. Until now, the mind does not climb how this could happen ...
