Located in tsukuba, ibaraki prefecture of Japan's industrial technology research institute, Japan's biggest solar power system. The solar panels at a cost of 800 million yen, covers an area of 6500 square meters, there are football pitches, used the four kinds of materials, such as monocrystalline silicon, respectively, set within the institute building, parking lot on the slopes of the roof and open space, a dc ac unit 21 sets, power up to 869 kw, and existing equipment together, more than 1000 kw power, electricity for 300 homes, is the crystallization of the latest technology of Japan.
China, Japan and South Korea as Asia's three biggest powers, has always been competitive in various aspects. A few days ago, South Korea announced that its manufacturing lithium battery submarine is superior to the previously made in Japan the world's first lithium battery submarine & other; Burn dragon number & throughout; 。 According to the previous Japanese media reports, & other; Burn dragon number & throughout; Applied in the military field may export to the Philippines.
manufacturing three KSS - South Korea prepared Type 3 lithium battery submarines. In September last year, South Korea's samsung company independent research and development made the first lithium battery submarine has been completed, the other two is understood to have been built in the 2024 years ago, and claims that can truly be put into use. Relevant personage also said, & other; South Korean company has the world's best lithium-ion battery technology & hellip; … ”
however, Russia has a little pessimistic experts made by South Korea's samsung, the submarine, don't think its technology level. Although Russia has also produce lithium-ion batteries used in submarine, but battery soon malfunction, can't really be put into use, thus, Russian experts & other; Despise & throughout; South Korean submarine is a justification for lithium-ion batteries.
it is known that used by the navy submarine in countries around the world, traditional lead-acid battery dominant position, but a breakthrough of the lead-acid battery can not further, performance in itself is not enough, and lithium ion battery as battery with popular nowadays, safe and reliable, some developed countries are seeking such as lithium battery power system development for submarine areas.
in addition to the lithium battery submarines, South Korea's work is also underway to develop a water battery in recent years, and is expected to be used for commercial. It is understood that the r&d team is working to improve water battery technology, so that its market in the future. Relevant personage says, seawater battery will also be used to military unmanned submarine and unmanned surface vessel.
