Pollution-free electric cars lithium battery run-up
Many cities limit, ban on electric bicycles One of the reasons are: lead-acid batteries used in electric bicycles, after the abandonment can not be effectively recycled, pollute the environment. By Changxing County, Zhejiang Xinghai Energy Technology Co., Ltd. self-developed lithium Digital Camcorder Battery power, from the fundamental solution to the pollution problem, can replace lead-acid batteries for electric bikes. Xinghai Energy Technology Co., Ltd. from 2003 began to develop lithium batteries for electric bikes. At Peking University, Zhejiang University’s support, the company invested 50 million yuan, successfully developed a lithium-ion battery power, the recent products through national laboratory testing.
According to reports, the power lithium battery using lithium nickel-cobalt-manganese oxide as the positive plate material, and join the nano-fiber fabric tubes and corporate self-developed dispersant HW-1, significantly increased battery high current ability to work; use of nickel belt as negative conductive plate so that the battery discharge the surface temperature is not obvious. At the same time, the company developed its own additive HW-2 electrolyte, using safety devices with independent intellectual property rights, can greatly reduce the burning of electrolyte solve the lithium batteries that may arise during the use of security issues.

Shanghai plans for the Beijing Olympic Games in 2008 to provide 100 hydrogen fuel cell vehicles, but by 2010, the World Expo 1000 will provide hydrogen fuel cell vehicles.
Frequent problems from the Japanese lithium Canon Battery fought in solar cell manufacturing enterprise
While the world’s lithium batteries have been recalled frequently a problem when the major battery manufacturers have set his sights on solar cells in order to meet rapidly growing demand.
March 3, the Japanese electronics maker Kyocera will invest 40 billion to 50 billion yen, in the fiscal year 2010-2011 before the company’s solar cell production capacity to 500 megawatts. It is reported that Kyocera will increase the plant equipment at home and abroad, introduction of higher performance new products.
In fact, Kyocera has already started overseas expansion plans. Kyocera solar cell is located in Tianjin, China factory expansion was the second capital increase successfully completed late last year. Expansion is completed, the Tianjin factory Kyocera solar panels monthly capacity of 3.5 megawatts or more.
In the meantime, the world’s largest solar cell maker Sharp will invest about 3 billion yen to improve solar cell production capacity from the existing 600 MW to 710 MW upgrade. While another solar cell maker Sanyo Electric Group, also plans to before the 2010-2011 fiscal year, at least invest 40 billion yen in the company’s solar cell business; Japan’s Mitsubishi Heavy Industries Group, the company also plans to increase solar cell production capacity nearly Canon NB-2L twice the .
The four Japanese companies accounted for 46.5% of the total output of solar cells. Order in connection with several other major rival to compete against the four companies have invested a huge solar cell business capital. With rising oil prices and the market demand for renewable energy an increasingly strong global sales of solar cells is growing rapidly, they can not pass up this opportunity.
New non-reflective coating materials, the birth of nanotechnology is expected to enhance the efficiency of solar cells and LED
According to the U.S. National Science Foundation (NSF) message, the U.S. Rensselaer Polytechnic Institute (Rensselaer Polytechnic Institute) researchers have recently developed an almost non-reflective coating of nano-materials, reflective rate is only currently used electronic equipment coating a fraction of the material. The material is expected to create more efficient light-emitting diode (LED) and solar batteries to create the conditions. The research is published in the March 1 of the “natural – Photonics” on.
The new nano-coating materials, optical materials, Rensselaer Polytechnic Canon NB-2LH Institute is the expert Fred Schubert and colleagues through the aluminum nitride (AlN) substrate deposited on silicon dioxide or titanium dioxide vapor to get. Researchers make silicon dioxide or titanium dioxide formed in the blanket-like AlN nanorod arrays, each root nanorods of about 50 nanometers wide, and to a certain angle oblique Qiao Zhao.
In general, the greater the difference between the two kinds of refractive index, light reflection through the interface will be more intense. In electronic equipment, reflecting the loss of light the surface of solar cells will reduce its energy conversion efficiency. Thus, a long time, scientists hope to find a way to control the reflex.
As a newly developed coating materials, the refractive index of air is almost the same, so reflections are extremely weak. Schubert said that the material of low refractive index due to its porous nature. Nanorod arrays by five-story lined up, the researchers realized the coating material of different refractive index of 2.03 from the bottom to the top of the 1.05 (air is 1), the total degree of reflection can be reduced to 0.1%. Another excellent performance of this new material is that it applies to many different wavelengths and incident angles of light.
Despite the paper’s lead author Fred Schubert and Jong Kyu Kim that they invented this new material is not in the windshield and glasses can be used, but the University of California, LED lighting expert Steven DenBaars said, “This is what I have seen anti-reflective effect of One of the best materials, Canon NB-3L nano-coating, which LED brightness can be increased by 5% to 10%. ”
Argentina’s restrictions on heavy metals in batteries for money
Recently, Argentina issued the relevant laws and regulations, for some cells in some of the biggest heavy metal content of the provisions proposed by the new limit.
A just legal provisions in force in Argentina, prohibit the production, assembly and import of cylindrical or prismatic shape, containing some heavy metals, carbon zinc and alkaline (Mn) of the original battery. These heavy metals and their maximum limit values were 0.0005% of mercury, cadmium and 0.015%, lead 0.2% (all weight percent).
The country’s existing laws and regulations introduced by the new battery, allowing it to continue to sell three years to December 2009.
In addition, the country’s Environment and Sustainable Development Department January 11 issued a resolution, provides for the maximum mercury button batteries limit of 2%.
Environment protection and energy Battery: walking in the fork in the road policy and Canon NB-4L consumption
From the 1997 nine ministries and commissions jointly issued the “battery products on the limited amount of the provisions of mercury” has nearly 10 years, but today, as the mainstream products in environment protection and energy battery – alkaline batteries in our coverage only to the battery products 20%
As always, at this year’s two sessions on the environmental problems are still widespread concerns, including environmental protection in China has been troubled by the focus of one of the problems — mercury pollution from waste batteries.
Response to national energy-saving, environmental protection policy appeals, production and energy-saving, environmentally friendly products, to effectively maintain social sustainable use of energy and environment for sustainable development, which is China’s current social development situation of the outstanding requirements, but also the manufacturing industry due The responsibilities and obligations. However, some manufacturing companies in response to national policy in place, the transformation of production of high quality environmentally friendly energy-saving products are facing the market test asked to promote the situation is not optimistic. Among them, the battery industry faces embarrassment on the market is particularly prominent.
One side is the pressure of the relevant policies, on the other side is the market reacted with indifference, no doubt those who have been determined to make a transition in alkaline battery production enterprises feel more lost. In the face of the formation of policy and market fork in the road, many Canon NB-5H battery companies exist such a question: in the end of the where to go? Policy-oriented market under the embarrassment of
In 1997, China Light Industry Association, the National Environmental Protection Bureau, Bureau of Technical Supervision Bureau and other ministries, nine launched “on the restriction of the provisions of mercury batteries,” the notice requirement, since January 1, 2001, the prohibition in the domestic production of various kinds of mercury batteries is greater than the weight of 0.025% of the cells; since January 1, 2005, the ban in the domestic production of mercury batteries is greater than the weight of 0.0001% of the alkaline zinc-manganese batteries (not mercury content of less than 2% alkaline manganese and silver oxide button batteries). Designed to take the lead source from the production of high standards and strict requirements, thereby bringing about market consumption, in order to achieve the popularity of environmentally friendly energy-saving battery.
In fact, the traditional carbon-zinc batteries for the pollution problem, there is a sense of responsibility in the policy promulgation of the battery business as early as the beginning before they take the lead in developing environmentally friendly batteries. The last century, the early 90s, the domestic battery industry to give up the boss at that time Nanfu unified domestic market, carbon-zinc batteries, the negative high mountains of debt for imported equipment from abroad and turned green battery manufacturing. In 1997, Nanfu Battery undertake innovative projects — the state “high-energy mercury-free alkaline manganese batteries and equipment development” research, and embarked on the road of independent innovation, and in 2000 completed the excellent research and development tasks, achieve a full range of alkaline batteries “no mercury, no cadmium, lead-free” and environmentally friendly production.
At the same time, many domestic enterprises have started large-scale cell production of environment protection and energy transformation of alkaline batteries, so as to drive the domestic alkaline battery production process. It is understood that in 1995 launched the first batch of environmentally friendly Canon NB-5L batteries when industry-wide production of alkaline batteries just over 10 100 million, and now has grown to 60 billion to 7 billion.
But the need to be aware that the alkaline batteries in absolute terms in recent years to achieve a doubling of growth in aggregate demand is based on the market under the premise of substantial growth, and alkaline batteries in the battery sales are slow growth in the proportion of At present only around 20%, not only in developed countries 80% ~ 90% of the high penetration rate far away from the national “Tenth Five-Year Plan” for 30% of the goals there is great distance.
According to the China Battery Industry Association Zhang Shanmei introduced in 2005, China’s battery production was 30.5 billion, but the alkaline manganese battery production is only 6.5 billion, accounting for about 20%, of which green mercury-free, low-mercury-free products has accounted for only 60 %. In foreign countries, as early as 1996, the United States, Canada, alkaline battery market share has reached 86%, and Japan in 2004 has reached 61%. Clearly, our consumers do not ignite consumer passion for alkaline batteries.
In fact, policy guidance, cell production, while energy-saving environmentally friendly batteries, the relevant state departments and industry associations are also actively doing business Tuiyou limit inferior work, and strive for environmental protection to create a good energy-saving battery consumption environment. Since August last year, started by the National Quality Supervision and Test Center battery-light special inspection, China Battery Industry Association decided to Nanfu, 555 in 11 brands of alkaline manganese Canon NB-6L battery identified as the first “green alkaline manganese batteries products”, to the community published recommended.
However, even at the national relevant departments and the joint efforts of manufacturing enterprises, environmental protection and popularization of energy-saving battery pace remains slow. The reason, many of the industry laid bare the truth: In the market, consumer links, there are great lies. The crux of environment protection and energy consumption of the battery
Policy orientation of the manufacturing enterprises often can play an immediate effect, but the impact of consumers have to play a much weaker.
While the battery environment protection and energy issue has attached great importance to all sectors of society, but in the eyes of the vast majority of consumers, the battery life is just the ordinary consumer goods, and soap, toothbrushes little different. “No. 1, a carbon-zinc batteries discarded after the 1 square meter of land can lose value, can make 10 cubic meters of water contamination,” such a concept, in the minds of many consumers is almost zero.
In addition, many consumers mind awareness of the potential savings are tied to the alkaline battery consumption. Because the price of alkaline batteries than ordinary carbon-zinc batteries high, many consumers feel that is more affordable carbon-zinc batteries, especially in the rural market, often laptop battery biased in favor of carbon-zinc batteries that the consumption of alkaline batteries was wasted.
Experts pointed out that this is a consumer misunderstanding. Although the price of energy-saving environmentally friendly batteries will be higher, but it reflected the energy-saving, environmental protection targets are ordinary carbon-zinc batteries several times. Like the first batch of 11 mercury-free “green alkaline manganese batteries products”, are the long-term storage, power and stability, but their mercury levels were below 0.0001%.
The south of Fu battery, for example, from the electricity index point of view, a Nanfu alkaline battery power is the same size carbon-zinc batteries of six times; from the environmental indicators point of view, alkaline batteries is almost no pollution to the environment; from life indicators point of view, the life of ordinary carbon-zinc batteries is 6 months, to maintain the original power capacity of 70%, Nanfu battery shelf life is three years, to maintain the original power capacity of 90%.
In addition, the alkaline batteries used in the production of materials and more energy saving society. Alkaline batteries do not use natural manganese ore, manganese dioxide, its use can be used or other low-grade manganese carbonate manganese ore for processing. The carbon-zinc laptop batteries are the main component of natural manganese, manganese ore discharge fewer resources in China, due to years of over-exploitation, the availability of discharge manganese nearly depleted.
In order to reverse the majority of consumer misunderstanding of alkaline batteries, many battery companies have done a great deal of market development work, every year spend a lot of marketing costs, but the effect was played less than encouraging. In addition, the battery business of publicity is limited to major cities in China, where the majority of rural markets, it is beyond the reach of the rural market. Guide consumption intensify strict law enforcement and the need
Today, the alkaline battery production enterprises is not only against loss and helplessness, there is the cruel pressure of survival. Of these enterprises in order to product transformation, is bound to increase the fixed assets investment, technical input, manual input and so on. It is understood that an annual investment Nanfu 2% of annual turnover to research and development. If the market does not generate sufficient returns, will inevitably badly shaken confidence in the development of enterprises, affecting the popularity of environmentally friendly energy-saving process of the battery.
In fact, the policy-oriented enterprises for environmental protection to the battery energy-saving requirements of the development, it is also engaged in guiding the work of market consumption. With regard to battery production and use of the relevant policies have explicitly pointed out: “to step up publicity and education, to encourage and support consumers to use mercury content of less than 0.0001% of the high-performance alkaline zinc-manganese Dell Battery; to encourage and support consumers to refuse to purchase and use of poor quality, and counterfeit battery products, and not properly marked on the battery identification products. “However, this policy, consumer groups, how much actually can cause reactions, but it is not known.
Prior to that, the battery in the consumers to have a greater response from the recovery matters. Carbon-zinc batteries in the general popularity of the times, when people see that after the recovery of the battery box will naturally think of things that the battery is not environmental protection, it should be put boxes for centralized treatment. Clearly, this state of civil actions initiated by the relevant departments to achieve a good recovery performance. Experts say: In the environment protection and energy the battery will become the mainstream of the times, if we can learn from this way of thinking, to guide people in popular awareness and consumption of alkaline batteries, they will certainly speed up the process of the popularization of environmentally friendly energy-saving battery.
“Nine ministries and the administration’s” notice “is given a very specific timetable, but also to the industry and all enterprises earmarked for eight years, and now time has passed to strengthen supervision and strict law enforcement should be put on the agenda of the.” China Battery Industry Association, vice chairman and secretary general Wang Jingzhong that: has now reached the standard mercury-free factories have strongly called for the strengthening of law enforcement is indeed a Latitude D820 Battery restructuring of the industry a good opportunity. Vision of the future development of the industry is that the battery industry, large and small manufacturers, constantly eliminated, development, so as to concentration, and size until large capacity. If so, that is a virtuous development circles.
Experts called for, whether it is to guide consumers, or strict law enforcement, need to intensify. After all, the battery companies can not afford to delay, the state can not afford to drag the energy and social environment can not afford to delay. Related links:
“Will be credited the cost of waste battery recycling sales prices, mainly in order to resolve the current of this embarrassing situation. This is part of the funds can be sold in the battery after the battery is specifically designed as the recovery of funds, thus effectively recycling used batteries.”
Song Xiaohua CPPCC proposals: the recycling of used Latitude D830 Battery has not attracted enough attention to the case, you can consider the cost of waste battery recycling credited to sales price.
