It is worth mentioning is that the Japanese trend of great importance to cooperation with China in the smart grid, Hitachi determine the experimental smart grid, environmentally friendly eco-city in Tianjin, China to cooperate with China in May. Mid-April this year, celebrities meeting in Northeast Asia, held in Nara, Japan and South Korea on behalf of the Environment and Energy Group Meeting on the next generation Grid, a lively discussion, Niwa Uichiro called attending the meeting as the consultant of the Itochu Corporation, Japan and Korea, including the United States on the development of smart grid now Niwa Koizumi was appointed Japanese ambassador to China, I believe he will play a certain role in promoting in this regard.

lithium ion battery electrode using lithium rechargeable battery material, lithium-ion battery storage capacity is 3-4 times the lead-acid batteries, hybrid vehicles use nickel-metal hydride battery twice, Asahi Kasei 1985, the company in the world the first successful development of lithium-ion battery, and Sony Corporation in 1991 as a product of lithium-ion battery market. Therefore, the lithium-ion battery by the Japanese media as the "battery" was born in Japan. 2008, the market share of Japanese companies in the world for more than 60%.

However, lithium-ion batteries currently in use build power is too small, and more for mobile phones, laptops and other portable devices, but as the battery of the solar power is not enough. According to reports, the household capacity of the battery takes about 5 kwh, equivalent to a cell phone lithium-ion battery 1700 times.

smart grid needs a variety of devices connected together, so the need to standardize the specifications, the U.S. Obama administration to foster new industries and vigorously support the development of smart grid, the American International Institute of Standards and Technology is related to the international standards in Europe to confront the development of different international standards. Japan would like to take the lift, her own expertise battery control system, transmission and distribution devices become the international standard, so actively cooperating with the U.S. smart grid test. At present, the most important co-operation, there are two, one is the Japan-US bilateral cooperation in Okinawa Prefecture and the Hawaii pilot smart grid. Another is 30 large companies in Japan Incorporated Administrative Agency New Energy and Industrial Technology Development Organization and Japan and the United States World Steel Pipe News , New Mexico to work together next fall in the U.S. smart grid demonstration experiments, the experimental site is the U.S. cutting-edge research focused Los Alamos and the state's largest city of Alba Kutch, mainly for family-oriented test, the use of smart grid residential construction focus on advanced technology. In addition to the New Energy and Industrial Technology Research Institute to participate in, as well as Toshiba, Hitachi, Shimizu Construction Company, the U.S. Los Alamos National Laboratory, through joint experiments.

Nomura Securities Financial Research Institute statistics show that the US-European research smart grid investment to 2030 will have reached $ 1.251 trillion, of which about 60% of development costs for the battery. Japanese domestic investment in this area to total $ 5 trillion yen in 2020. The importance of the battery in the smart grid is evident.

Japan in 2030, all universal smart grid. Meanwhile, Japanese officials and the public one out to promote smart grid in overseas construction, environmental energy field has just introduced this month, Japan's new growth strategy will focus on emerging industries, plans to record more than 50 trillion yen market by 2020, to increase employment 1.4 million people. The smart grid is an important part.

Fortunately, Japan's large-scale lithium-ion battery research and development is in full swing. Mitsubishi Electric Corporation diameter of 1.8 cm, 6.5 cm high cylindrical lithium-ion battery connected to charge storage at the same time, has been successfully tested and launched in March a small combination battery 312 lithium-ion battery, the electrical storage capacity of 1.6 kWh, the price of ¥ 200,000. Further develop a small portfolio battery pick up can become a bigger battery, the use of solar power parking, convenience stores, etc. can be used for charging electric vehicles, electric motorcycle, and can also be used for lighting at night. Similarly, the more connected a large battery, it can be a "huge" battery. This fall, Mitsubishi Electric Corporation is located in Hyogo Prefecture, the plant is scheduled to 290,000 notebook computer lithium-ion battery connected to the electrical storage capacity of 1500 kwh, the factory setting power of 1000 kwh of solar panels, solar power generation all Xucun. At present, the development of large-scale battery more and more companies World Pipe network informed, Mitsubishi Heavy Industries Co. and Kyushu Electric Power Company 448 battery connect successfully made the charge storage capacity of 132 kwh battery.

smart grid is one of the advanced technologies for effective use of solar power and green energy. Solar energy compared to fossil fuels, inexhaustible, inexhaustible, one hour exposure to the Earth's sunlight into electricity, enough of the world consumption for one year, at the same time, solar power does not emit planet-warming carbon dioxide gas is the best choice for the human. Japan on the one hand lack of energy, in addition to nuclear power, energy self-sufficiency rate of only 4% of oil dependence to 50%; the other hand, the Kyoto Protocol entered into force in 2005 and 1990, Japan from 2008 to 2012 years, carbon dioxide and other greenhouse gas emissions by an obligation to a decrease of 6%, these objective factors to force Japan to vigorously explore the potential of the smart grid.

smart grid has long been a hot topic in the world, Japan is one of the few advanced countries, a lot of experiences and learn from.
