Recently, Japan successfully developed a capacity than the existing eight times a new battery, it is understood that the new battery is referred to as lithium sulfur batteries, since in recent years, Japan is to the lean the strength of his whole battery research and development, it was not long ago, with the Japanese kansai university soup shallow company finally successfully developed the lithium-sulfur battery samples, the battery capacity per hour of 8 amp, It is eight times larger than existing lithium-ion batteries, which is the world's leading technology. Did Japan really underestimate its capabilities? Is it true that China will not be able to catch up with Japan for 10 years? For the battery, remember to give me a triple loop.

Japan's research and development of lithium sulfur batteries, is indeed a practical very large new energy, since the 1990 s, more and more things in People's Daily life with the battery, in modern times, both laptops, mobile phones or video cameras and other electronic products, and new energy vehicles such cutting-edge technology, currently used in lithium ion battery, Although the current lithium ion battery industry chain is highly developed, this kind of battery also has high stability, but its endurance is always a big problem, for ordinary electronic products there are not so many problems, but for the rapid development of new energy vehicles, the endurance is an unavoidable problem.
Due to the poor battery life of lithium ion battery, new energy vehicles using this kind of battery will be charged once every 100-150 kilometers on average. The cost of charging each year is not lower than that of fuel cars. Therefore, in addition to continuing to improve lithium ion battery, countries are also looking for other energy to replace lithium ion battery. Lithium sulfur batteries for lithium ion batteries is one of the ideal object, with the use of sulfur material, lithium sulfur batteries in theory can be done in the case, almost the same performance in the life to about 10 times of ordinary lithium ion battery, if you use this kind of batteries, a new energy cars are likely to need to charge 5 times a year, can meet the demand of most of the trip.

In addition, due to the lithium sulfur batteries in no doped nickel and cobalt elements required for production, so on cost compared to lithium ion battery can also further reduce, though the prospect of lithium sulfur batteries is very bright, but the battery at present is still in the primary stage, the development of lithium sulfur batteries in Japan were capacity is 8 times of ordinary lithium ion battery, but repeated use only a few times, This is obviously not ready for practical use, and Japanese companies will need to improve the performance of the negative electrode at least for practical use, a process that will take at least five to eight years.
In the whole world, Japan is not the only country interested in lithium-sulfur battery. China is also carrying out relevant lithium-sulfur battery research. As early as 2016, China Kepi Energy Storage Technology Company has begun to develop lithium-sulfur battery project, and last year, Chinese Academy of Sciences published a number of papers on the characteristics of lithium-sulfur battery. This means that China's lithium-sulfur battery technology and Japan's are basically at the same starting line. Given China's increasing subsidies to the new energy vehicle industry in recent years, the two countries that started at the same level may end up with China's victory.

Lithium sulfur batteries in general, for Japan, China isn't worry too much, after all, oneself also have related technologies, to worry about is Japan, if Japan could not be sulfur in lithium battery technology beyond China, then in the existing lithium-ion battery industry completely under the condition of "rule" by China, the development of the Japanese in the battery industry will be increasingly vulnerable.
