Japan's evolution: lithium battery life will be more than 500 kilometers

According to 'Japanese economic news' reported on December 27, 2018, 1 time charge can travel between Tokyo and Osaka 500 kilometer of lithium ion battery technology development are becoming more active in Japan. Water chemical industry technology has a breakthrough idea, agms have also been close. All can use the existing electrode, through the first half of the 20 s of this century is expected to achieve practical application.

meti will support the technical development of battery performance into full play. Worldwide, moving to a pure electric vehicle, EV) Trend is accelerating, if range greatly extended, as the subject in lithium ion battery for lead time or will continue to continue.

if in the fully charged state can travel 500 km, to match the performance of the gasoline vehicles. Meti etc. Think this is one of the conditions of pure electric vehicles popularization, put forward to achieve the goal of 2030. Rapid expansion in the pure electric vehicles in China over the distance less than 150 kilometers of the models of subsidies, subsidies increases the radius of long vehicles.

commercialization of lithium-ion battery in 1991, has been used in laptop computers and video cameras, etc. Type 2009 is used in the production of pure electric vehicles. Fully charged the distance can travel at about 200 kilometers. It is generally believed in the early 2010 s with the technology to meet the 500 kilometers, by 2030 will be all the solid battery before and after a new generation of replace battery.

the development of a new generation of batteries in the increasingly active worldwide, but a lot of technical subject. On the other hand, the lithium ion battery technology development progress, 500 kilometers of breakthrough increasingly realistic possibility. Researchers such as forecasting & other; Lithium-ion batteries still can continue to use 10 years or so & throughout; 。

lithium ion batteries with lithium ions move between the positive and negative electrodes to generate electricity and batteries. To increase the battery capacity, it is necessary to increase the ion electrode in storage, or reduce the internal resistance, make the electronic through more easily.

the water chemistry is used in the anode technology development, in the structure of carbon materials added, make it easier for electron flow. Expand of the anode through channels, electronic flows more smoothly and reach about 10 times in the past. In addition to large for the current, electrode is not easy to damage, improved durability.

will make more positive, so that more lithium ions. In the experiments, the capacity of the battery raised about 3 as. Can be up to 400 km distance from the current level of more than 500 kilometers. By 2021 as spare parts sales.

agms are through to the cathode mixed with silica, improve the capacity 2 into left and right sides. To join in using carbon materials of the cathode silicon material, facilitates the storage lithium ion, can increase the capacity. But, have in the case of capture part of the ion can't release problem. Through in the negative ion in advance, captured part does not produce activity, lithium ions and release becomes smooth. Agms strive to achieve practical application in a few years later.

in addition, the use of previously non-existent electrode materials in advance. Serval inside straight Ming, a professor at the yokohama national university cooperate with panasonic, developed with fluorine of the anode. Is not only a metal, oxygen can also be used for electrode in the electron flow, capacity to 2 times. Sumitomo chemical to promote the development of aluminum anode, put forward to improve the capacity to 2. Five times the goal.

the Japanese economy, trade and industry since 2019, the development makes it possible to completely run out of lithium-ion battery technology. In order to prevent fire accidents, to below the upper limit the capacity of the battery. Will support can accurately detect sensor soc development, increase the usage. Included in the 250 million yen in the 2019 annual budget, and strive to implement practical by 2023.

Japan has swept the world in the field of lithium ion battery, but patent applications appear to reduce after 2011. The patent application in China, universities and enterprises to increase, by 2015, for the development of Japan and China each account for a third of the whole. In order to increase the radius, significantly increase the battery capacity of technology development is moving forward, China's patent application is expected to further increase.

Neoen above said the battery energy storage system (supplied by the company The official called Hornsdale Power Reserve) Instant response and complete synchronization and frequency variation, and in this case is triggered by the Queensland generator fault, the generator is one of more than 100 generator. In the past 12 months, the generator often fail.
