Japan’s solar cell market will shrink system

Recently, the market research firm Fuji energy-related economic system released the findings of the Japanese market. According to the survey results to predict the future, solar cell systems in Japan’s market will shrink. 2007 (April 2007 ~ March 2008), the Japanese solar cell system related to sales of 148.7 billion yen, while the year 2016 is expected to be reduced to 114.3 billion yen.

Because raw materials do not use silicon or silicon reduce the use of solar battery system is constantly expanding market, the system’s average price has declined, and the stagnation of domestic demand growth in the field of increasingly intense price competition, so Fuji economic forecast, the amount calculated by The solar cell market will shrink. The organic solar cell, estimated 2016 annual sales in Japan will reach about 2.4 times the annual 08 or 55 billion yen. This non-silicon solar cells are expected to increase, so the number of calculations predict the market will go according to Wang.

Hybrid lithium-ion rechargeable battery will pull the growth of the market

Fuji economic forecasts, after 2010, the Japanese lithium-ion rechargeable battery market, driven by demand for hybrid vehicles in the field, will be expanded. 2016 annual sales in Japan will reach 07 to about 2.9 times the 110.8 billion yen.

LED lighting in 2011 will exceed the frequency fluorescent lamps

Fuji economic forecast, the year 2015, lighting (fluorescent and LED lighting commercial frequency) Japan domestic sales will increase about 2.6 times of the year 07, about 41.9 billion yen. The formation of LED lighting market faster than initially forecast, major manufacturers are expanding investment in equipment. Fuji economic view, LED lighting market in Japan in 2011 will surpass frequency fluorescent lamps.

Battery technology will occur in two changes

Lithium-ion battery charge and discharge mechanism completely different from the lead-acid batteries, nickel cadmium batteries and nickel-metal hydride batteries. After the three commonly used battery electrode by electrochemical reaction, conversion of other compounds to store electricity. The lithium-ion battery is by coating the electrode active material on the storage and release of lithium ion, lithium ion through the electrode active material on the "embed" and "emerge" through the so-called "de-embedded phenomenon" to store energy.

Because of recent times have been found in a variety of institutions can be stored (ie, embedded), release (or prolapse) ion electrode active materials, solid electrolytes and polymer membranes, together with the people of these newly discovered substances in-depth study, and then On this basis, but also the structure of the innovative transformation of the battery, so "embedded de-ion battery," the performance of rapid increase.

Japan, U.S. and German scholars generally expected that by 2015, 2030, two years, embedded de-ion battery manufacturing costs will be reduced to now the price of 1 / 7 and 1 / 40. Currently, many foreign research institutions are stepping up to this practical battery technology research, and some have been in the waiting stage of industrialization. In other words, expected from the pages of this century, the embedded de-ion battery performance, structure and manufacturing costs will certainly meet people for the high-pressure, high-capacity ion batteries have high hopes, the BEV, PHV in performance, the real price and have used a variety of advanced technology, continuous improvement of the M1 is still petrol passenger car class competition, and to mass production according to market principles (not funded by government or private sector), thereby reducing car pollutants and greenhouse gas emissions and change the car's "food" structure, making the car's driving energy costs significantly.

Found that can be used to "de-embedded response" many of the inorganic solid electrolyte conductivity is very high, very fast charge suitable for the manufacture of high voltage, high energy density batteries.
"Auto industry restructuring and revitalization plan" put forward in the next 3 years, China will form a 500,000 capacity all kinds of electric vehicles. To accomplish this task, ion battery production capacity must first be met. However, China has such advanced battery development and production planning? To produce, a liquid electrolyte the "iron battery"? Or laminated solid electrolyte for lithium ion batteries? Unknown. Japanese, German auto industry has been the driving force of the future of electric cars locked in the "laminated solid electrolyte for lithium ion batteries" on. However, lithium-ion battery manufacturers in China even the "liquid electrolyte lithium-ion battery" is also required for membrane materials can not be produced so far, all have to rely on imports more expensive, accounting for 30% of the cost of power than the battery! In recent years, the international battery manufacturers and multinational auto companies generally composed of various types of joint ventures, joint development of electric vehicle battery technology, but few of such examples. In this set up on the basis of the 50 million electric vehicle production capacity, is an independent type or attachment type, difficult to judge.

Recently discovered a large number of excellent lithium-ion batteries or "non-lithium batteries," the alternate positive and negative active material for a new generation of vehicle power battery research and development, promote the use of essential, but also will promote the rapid development of various types of electric vehicles. For example, the relevant foreign agencies have recently found that "sulfide lithium-ion conductor" became crystal material, the existing lithium-ion conductivity is high, there are wide "electrochemical window", therefore, it is likely to become a solid battery electrolyte (solid electrolyte). In addition, the glass state lithium-ion solid electrolytes, non-integer ratio of compounds and some other lithium-ion battery cathode, anode active materials that alternate, but also much industry attention.
To be sure:

First, will debut in 2015's "preemption" battery will not be the "iron battery", is likely to be non-lithium compounds "embedded de-ion batteries."

Second, will be available before and after 2030 the "innovative" batteries will not be the "iron battery", it should be a high-capacity, low cost, "embedded detachable battery," it will find extensive use of new types of electrode active materials and auxiliary materials. For the second conclusion of the discussion, will be launched in the next column.

The implementation of the battery electric vehicle anti-theft number plate system

With the popularity of electric bicycles, in actual use, a very troublesome problem for consumers there - electric vehicles and electric vehicle batteries stolen frequently. According to the survey, many people have been lost in Yangzhou or battery electric vehicle experience. It is understood that the replacement of the current electric vehicle batteries, about 70% of consumers are victims of theft battery.

Recommended

Related to the implementation of military members suggested that electric vehicles number plate system. By the public security, industrial and commercial producers can carry an identity card similar reference electric bicycle license plate, license plates should be specified in the buyers name, invoice number, electric cars and steel to match the battery. The vehicle license plate provided in the sales of electric car, the corresponding increase city and out of the city crossing the mouth of the check card, such as providing no license plate, or vehicle with the battery does not correspond to the number of persons, vehicles and batteries to thorough investigation Department. Who do not receive before the car's license plate, with the original purchase invoice to the car at the replacement, so that stolen cars, the battery Xianchuyuanxing.

Increase investment in video surveillance devices by the use of public security monitoring checks at any time. Banks, shopping malls, hotels, business centers must force the installation of the door; hope still practiced in front of an effective system of security lump sum, restaurants, shopping mall security responsibilities should be clearly responsible for the inspection, should bear some loss of joint and several liability. Can increase the security of electric vehicle batteries propaganda, incentive intensity.

In addition, the proposed electric vehicle production and sales of the manufacturers and sales departments to improve electric cars and battery technology content of the safety locking device, anti-theft insurance factor to enhance the battery to prevent loss. At the same time, it is recommended to do electric car electric car manufacturing industry and the car battery corresponding relationship between the number of the form in order to find the owner as soon as possible after detection, and to the owner to become the most important witnesses alleged thief, so the thief to justice as soon as possible.

Battery drop in demand

Decline in demand lead smelting enterprises battery cut winter park

China's largest manufacturer of lead Ling lead a new industry, said the global economic slowdown has spread to battery manufacturers, lead the domestic manufacturers have stopped production. Ling lead the new business manager, said, "The majority of lead smelters have cut production or shut the whole plant, the new capacity of 100,000 tons Ling has 60% idle," and he further added that "no one can predict when the market will recover" .

It is understood that the main battery electrodes made from lead. At present, China mainly lead-acid batteries car batteries, accounting for about 60% of the total. As the financial crisis broke out, China's car consumption also fell, to lead the industry to combat serious.

Prior to this, 27 domestic and smelting enterprises and Zinc Mine, announced the cut of 5% to 10%, the joint limited production, cut, cut rate would be around 10%.

Industry analysts pointed out that the deteriorating global economy to cars, toys, telephone needs, the battery will be a decline in demand. Currently, the lead futures fell 52% this year, the market for the first time in six years into oversupply.

CUP analysts believe that the joint limit of lead and zinc production enterprises is limited. The costs are soaring lead and zinc industry, the product price has been dropped. "The whole industry is facing excess supply of primary products to the test, the situation will be more severe next year."

Not only lead the industry in order to encourage buyers to sign long-term orders, yesterday, the world's largest copper producer Codelco, Chile business next year's trading of copper exports to China down 32% surcharge, from $ 110 per ton this year, down from 75 per ton dollars.
