Japan's why a soft spot on the lithium ion battery

In the near future, there will be such a scenario, the installation of monitoring in the home kitchen wall unit roster will have a " 92P1073 battery", if the blue skies, sunshine, solar panels on the roof of a large amount of heat into electricity, electricity generation sufficient battery display data is "full power", in addition to available air conditioning, TV, refrigerator and other appliances to use, the electric vehicle charging can guarantee supply. Finish their home, can be divided as part of a neighbor.
An era is approaching a battery. With the use of solar power growing numbers of households, and large batteries to accelerate the development, not use up the power Xucun up and delivery to the region's smart grid, automatically adjusting power in the local area. Bring this vision into a reality of life, battery indispensable. The future is the leading battery life of lithium ion batteries.

Lithium-ion battery is lithium electrode materials of rechargeable batteries, lithium-ion battery charge storage capability, the same lead-acid battery is 3 to 4 times that of Ni-MH battery hybrid double Asahi Kasei Corporation in 1985 for the first time in the world the successful development of lithium-ion battery, 1991, Sony lithium-ion battery as a product to market. Therefore, the lithium-ion batteries by the Japanese media as "born of the battery." 2008, Japanese companies in the world market share of 60%. March 25 this year, Panasonic, Osaka notebook computer lithium-ion battery factory completed the first phase of the project, the plant can be monthly 10 million lithium-ion battery, the second phase of the project scheduled for completion by 2011, to produce 5,000 hours per month 10000 lithium-ion batteries, lithium-ion battery market share of the world will tilt further to the Japanese. laptop battery

However, the current lithium-ion battery charge capacity is too small, and more for mobile phones, laptops and other portable devices. As a solar power battery is not enough.

The capacity of domestic battery takes about 5 kwh, equivalent to lithium-ion cell phone batteries 1,700 times, usually lead-acid batteries to achieve this capacity, the volume size of a small house, and the average family is not easy to free up so much space, if the lithium ion battery, size, and air-conditioning almost every family can be placed.

The development of large lithium-ion batteries are in full swing, based on the results in the development of existing large-scale battery is a shortcut, laptop lithium batteries already popular, Mitsubishi Electric Corporation to 1.8 cm in diameter, 6.5 cm high cylinder-shaped lithium-ion the battery connected, and charge storage, successful, in March launched by the 312 small-scale lithium-ion battery consisting of combination of battery, electrical storage capacity of 1.6 kwh, the price of 20 million yen. Use the existing battery connection and re-development of large battery portfolio, 92P1077 compared with less investment, low cost, quick.

To develop a small portfolio to further take up the battery, the battery can become a greater use of solar power in the parking lot, convenience stores can use, storage electricity for lighting at night. Solar power can also combine with the battery electric vehicles, electric motor charged. Increasing aging of Japanese society, more and more elderly people in wheelchairs, in every corner of the street, set the battery charge for the electric chair, hands and feet moving more convenient inconvenient for the elderly, to go further.

Similarly, more large-scale battery connected, it can be a "big" battery. This fall, Mitsubishi Electric Corporation's plant in Hyogo Prefecture, plans to 290,000 notebook computer lithium-ion batteries connected together, electrical storage capacity of up to 1,500 kwh, the factory setting has the power to 1000 kWh of solar panels, solar generation of electricity can all Xucun up.

The popularity of large-scale 92P1102 battery technology on the smart grid utility indispensable, solar power, wind power to tell the truth are somewhat dependent on the weather, unstable electricity ups and downs, in order to protect the power supply, battery is the essential facilities. Sunny, wind strength, generating a large quantity, can Xucun up to prepare for without the sun, when the use of small wind. This can really adapt to nature, and nature coexist in harmony. In this sense, it would be "everything becomes possible" a form.

Nomura Securities Financial Research Institute of the statistical data show that the smart grid research on the United States and Europe by 2030, total investment will reach 1.251 trillion U.S. dollars, of which the development costs for the battery about 60%. Battery of the importance of smart grid can be seen.

Large lithium-ion batteries real practical use, also need to address many issues:

The first is cost, currently made of a 1 kWh cost of large lithium-ion battery approximately 100,000 yen, made suitable for household of 5 kWh of batteries, 08K8196 the cost of up to 50 million yen, so people hardly expensive batteries to accept, to let it "fly into the homes of ordinary people" and must reduce costs.

Second Life issue, more delicate lithium-ion batteries, life is too short, Hitachi hardly managed a successful system life of 10 years in large lithium-ion batteries, solar panels, but now life is 20 years, the two time does not match in the middle to replace the battery, not only increasing the financial burden of the user, but also bring trouble to the user.

Again, and now the development of large lithium-ion batteries are the single test items, in the safety assessment is not authoritative, the need for mass production, on the intelligent power supply system for authentication.

Japanese government in 2020 greenhouse gas emissions reduced by 25% compared with 1990, the popularity of solar power is imperative, therefore, the Ministry of Environment suggested the use of solar power generation family from 2005 to 26 million to 10 million, 08K8194 Lithium-ion battery strong market demand will inevitably bring rapid progress, every street corner has a battery of age footsteps have ears
