China's lever to shake the world has appeared, and such good news should be included in my blog as an exception. According to the technical data listed below, the energy density of high-speed rail battery can reach above 1000w/kg, and the discharge current is 3- 10 times that of ordinary battery. The discharge curve of high-speed rail battery is gentle, and the discharge time of more than 70% is1.2-1.5v. The raw materials are abundant, the cost is low, and it is green and pollution-free without recycling. Fast charging 10 minutes can reach 50% of the power, and it only takes 9 hours to charge slowly with ordinary sockets at home. I am very excited to see such data. The emergence of this kind of battery is enough to subvert the current automobile industry and even the energy industry. It is no exaggeration to say that it is the outpost of an energy revolution. The author discussed in detail in the article "Zero Emissions of Greenhouse Gases and Electric Vehicles" and put forward suggestions to the central government, strongly demanding the establishment of a national power supply company specializing in battery production and leasing, and implementing a national monopoly and recycling system for all batteries with the same specifications. Here, you can imagine that a set of 2-4 tons of batteries, plus a specially designed constant power torque transmission motor, without a gearbox, can carry at least 10 tons of materials, ammunition and weapons on the Type 99 tank, and transport the batteries with a transport vehicle of 20-40 tons. Haha, old rice can only bow down. It really shows how amazing China people are, and they dare to teach the sun and the moon to change the sky.
China changes the mass production of BYD iron battery in the world.
At present, the power supply of digital cameras is mainly lithium-ion rechargeable batteries. Lithium-ion batteries have many advantages, such as large capacity, light weight and no memory effect, but they also have many disadvantages, the most prominent of which are poor safety, short circuit, fever and so on, which are easy to explode. Reports of battery explosion hurting people are often seen in newspapers. Secondly, although the capacity is "large", it is not enough to meet the development needs of digital cameras with higher and higher pixels, larger LCD and stronger video recording function. People generally look forward to the advent of batteries with better performance.
In the past, people focused on fuel cells, but due to the complexity of technology, fuel cells still have a long way to go in miniaturization and safety. Recent reports about BYD's new energy vehicles have aroused people's concern: this new type of battery is much better than lithium-ion battery in many aspects, and it is closer to fuel battery in practicality, which is expected to provide continuous energy for our digital cameras in the near future. It is exciting that BYD is in a leading position in the application research of iron batteries, and China will change the world again in this field.
What is an iron battery?
At present, there are two kinds of iron batteries studied at home and abroad: high iron and lithium iron. BYD iron battery seems to be the former, and no other manufacturer claims that its products can be applied on a large scale except BYD.
High-iron battery is a new chemical battery with high energy density, small volume, light weight, long service life and no pollution, which is synthesized from stable ferrate (K2FeO4, BaFeO4, etc.). ).
Advantages of iron battery:
High energy and high capacity. At present, the specific power of civil batteries on the market is only 60- 135w/kg, while that of high-speed iron batteries can reach more than 1000w/kg, and the discharge current is 3- 10 times that of ordinary batteries. It is especially suitable for occasions requiring high power and current. High-speed rail batteries are cost-effective. At present, alkaline manganese batteries can not meet the needs of digital cameras, video cameras and other electronic products that require large current and large capacity, and lithium-ion batteries are not very competitive in this respect because of the cost.
The discharge curve of high-speed rail battery is gentle. Such as Zn-K2FeO4, more than 70% of the discharge time is1.2-1.5v. ..
Rich in raw materials. The most abundant elements in the earth's crust are aluminum and iron. The iron content in the crust is 4.75%, and the manganese content is 0.088%. At the same time, each mole of +6 valence iron can produce 3 moles of electrons, while each mole of +4 valence manganese can only produce 1 mole of electrons. The consumption of iron is only 1/3 of that of manganese in the case of its own abundance, which greatly saves social resources and reduces the cost of raw materials. On the market, MnO2 is about 9000 yuan/ton, and Fe(NO3)3 is about 7500 yuan/ton.
Green and pollution-free. The product of ferrate discharge is FeOOH or Fe2O3-H2O, which is non-toxic and pollution-free and environment-friendly. No recycling is required.
News link: Nissan's old brand has a pleasant journey. Domestic batteries subvert the old market structure (Source: Consumer Daily Author: Chen)
Domestic batteries have finally ushered in the moment of "open sesame" in the capital market.
In September, Shenzhen BYD Group's latest patented technology "iron battery" entered the countdown stage of market operation. If the application is successful, it means that the battery manufacturer, which ranks second in the world in rechargeable battery production, will subvert the current automobile world and realize four-wheel drive and stepless speed change of electric vehicles.
Although there are many questions from the outside world, foreign giants in the industry still dare not underestimate. The reason is that "BYD once broke through the' forbidden zone' caused by the monopoly of the battery industry by independent research and development, and strongly reduced the once high-priced mobile phone battery from the' price' of 1,000 yuan to the' parity' of several tens of dollars now, so that the mobile phone gradually changed from aristocratic consumption to civilian consumption."
Mr. Jiu Nan Shirai, R&D Commissioner of China for Japanese lithium-ion power battery project, expressed the above feelings in public more than once. He told reporters that since the 1980s, Japanese manufacturers such as Fuji, Toshiba and Panasonic began to develop and produce disposable alkaline batteries. From the late 1980s to the early 1990s, Japanese disposable batteries entered the China market to look for foundries, and he had already paid attention to the consumer market in China. "In this period, both the popular BP machines and the portable radios, alarm clocks and miniature flashlights that are still in use today need a lot of disposable batteries. Although China battery manufacturers such as Shuanglu, Fu Nan and Baixiang appeared at that time to produce disposable batteries in batches, the long-term output was large and the output value was low. It can be explained that domestic batteries at that time have been in the downstream of the industrial chain due to the lack of core technology. "
To Mr. Shirai's surprise, only 10 years later, domestic battery brands developed disposable batteries with independent intellectual property rights. In 2004, Shuanglu Battery began to develop the national torch plan project, namely LR6 alkaline digital king battery. At present, its alkaline battery products have also developed from LR6 to LR20, ZR6, ZR03 and other 12 series, which basically covers all alkaline battery product lines. "Reflected in the consumer market, Japanese and European and American brand batteries are shrinking in the domestic market, while China brands are gradually entering overseas markets."
At the same time, it was Liu Guoen, editor-in-chief of a science and technology website in Beijing, who confirmed this change to reporters. He defined this period as the first watershed in the development of domestic batteries. "This is the stage when domestic batteries sacrifice the market for technology, and it is also the secret of the rapid development of many domestic battery companies." Since then, in 2005, China Battery Industry Association officially released the "Comparative Test Results of Ni-MH Battery Products in the Market" for the first time, which also showed that domestic brands such as Fu Nan and Shuanglu were obviously superior to Nissan's old batteries in performance and price.
Actually, the benefits are obvious. In 2003, GlobalSourcesLtd released a market information report entitled "Production Capacity of Battery Suppliers in China". The report shows that China's annual battery output is 654.38+09 billion knots, which is recognized as a producer of primary batteries. The average annual output value of this industry exceeds $4 billion. It is estimated that there are more than 2,000 battery manufacturers in this area, of which 300 produce export products. Finally, the report predicts: "China is now the world's largest supply market for non-rechargeable batteries, and it will soon become a major producer of rechargeable batteries."
As it says. Soon, with the introduction of rechargeable secondary batteries, domestic batteries reached the second watershed. "At the beginning of this stage, no enterprise in China can produce secondary batteries. At that time, the global secondary battery field, regardless of nickel chromium cadmium, nickel zinc hydrogen and lithium batteries, was monopolized by a few Japanese companies. " Liu Guoen said, "However, domestic battery companies rely on independent research and development, and finally break through the industry monopoly of Japanese companies, and strongly reduce the high value of secondary batteries to the parity stage."
At the same time, domestic secondary battery manufacturers have also completed the original accumulation. Until around 1998, a "mobile phone" of 30,000 yuan and a nickel-cadmium battery made in Japan cost more than 1000 yuan. However, after the domestic battery is manufactured, even if it is sold in 600 yuan, plus the maintenance cost, the profit is still 50%-60%, and the profit margin is very considerable. Xia Zuoquan, the founder of BYD, once said frankly: "BYD successfully entered the field of mobile phone batteries in just a few years, which not only broke the monopoly of Japanese companies, but also made a lot of profits."
As one of the direct results of this innovation, domestic batteries with low price and good quality are rapidly diversified in the consumer market. "Mobile phones, laptops, MP3 players, digital cameras ... almost all digital products you want are inseparable from batteries." Liu Guoen said happily that batteries are also used in industrial cordless equipment, standby power supply, military and medical markets.
At the same time, mobile phones, laptops, Bluetooth headsets, PHS phones, mobile DVD and other electrical appliances are all developing in the direction of portability. All these make small and light batteries popular.
What Mr. Shirai regrets is that the development of secondary batteries in China only took less than 10 years. The lithium battery market forecast released by Irish ResearchandMarkets also shows that the output of large-scale lithium batteries (disposable batteries and rechargeable batteries) in China ranks first in the world. China accounts for 23.8% of the global total output of lithium batteries.
Moreover, the idea of using domestic batteries for development goes far beyond this. 1997, nine ministries and commissions jointly issued "regulations on limiting mercury content in battery products". The aim is to take the lead in high standards and strict requirements at the source of production through the baton of policy, and then drive market consumption and realize the popularization of environmentally friendly and energy-saving batteries.
In fact, long before the promulgation of the policy, domestic battery companies began to take the lead in developing environmentally friendly batteries. In 2000, Fu Nan battery realized the environmental protection production of a full range of alkaline batteries, which were mercury-free, cadmium-free and lead-free. Since then, many large domestic battery enterprises have also begun to transform to produce environmentally friendly and energy-saving alkaline batteries, which has led to the production of domestic alkaline batteries. It is understood that when the first batch of 1995 environmentally-friendly batteries went on the market, the output of the whole alkaline battery was more than 100 billion, and now it has increased to 6-7 billion. Since August last year, the mercury content in alkaline manganese batteries of leading enterprises such as Fu Nan and 555 1 1 has been lower than the mercury content limit index of mercury-free batteries.
News link: BYD iron battery is the first automobile power revolution in the world (Source: Shenzhen Special Zone News Author: Blue An Xu An)
The first dual-mode "ferroelectric" car "F6" is expected to be launched next year.
The curtain of the high-tech fair has not yet been opened, and the good news of new technological breakthroughs has come frequently. Yesterday (10), BYD released the world's first iron battery at the convention and exhibition center, and announced that the commercial use of iron battery is mature-F6, a dual-mode hybrid vehicle powered by iron battery, is expected to be put on the market in 2008.
According to reports, BYD's iron battery is superior to lithium battery in three core indicators: high capacity, high safety and low cost. Not only is it expected to bring an electric vehicle industrial chain to Shenzhen, but it is also expected to become an energy substitute for notebooks, mobile phones and electric toys in the future.
BYD's iron battery was first commercialized.
It is understood that compared with traditional Ni-MH batteries and lithium batteries, the iron battery developed by BYD has inherent advantages: the world is rich in iron resources, and iron is cheaper than nickel and lithium metals, and its environmental protection will not cause pollution caused by the abandonment of Ni-MH batteries and lithium batteries.
As early as a few years ago, BYD organized a research and development team of 500 people and started the research and development of iron batteries. After tens of thousands of experiments and tests, BYD successfully developed a special iron battery for electric vehicles, named "ET- POWER". The relevant person in charge of BYD said that it represents BYD's latest scientific research achievements in the field of batteries, in which E stands for environment and electricity, T stands for technology, and power stands for power and energy. BYD named the new technology of automobile power with "ET-Power", which means future technology and future automobile power.
BYD F3e equipped with "Iron Power"
It is understood that the voltage of each "ET-Power" iron battery is 3.3 volts. At 60 amps, the number of battery charging cycles can reach more than 2000 times, and the continuous mileage life of the battery is more than 600,000 kilometers. Take F6 dual-mode electric vehicle as an example. It uses 65,438+000 iron batteries, has a fully charged cruising range of 430 kilometers (65,438+000 kilometers in electric mode+330 kilometers in hybrid mode) and a top speed of 65,438+060 kilometers per hour.
Compared with the most widely used lithium battery at present, BYD iron battery not only has the advantages of low cost and environmental protection, but also is superior to lithium battery in battery capacity, cycle life, service temperature range and discharge performance due to its brand-new design. In addition, due to the use of high thermal stability materials and careful process design, the safety and reliability of BYD iron battery are greatly enhanced. Contrary to the explosion phenomenon that may occur when lithium batteries are improperly used, iron batteries are safe and reliable, and will not explode even if thrown into a fire.
First applied to BYD dual-mode power vehicle F6.
At the press conference, BYD released the world's first dual-mode hybrid vehicle F6DM driven by an iron battery motor and a gasoline engine, and its core power battery is ET-Power.
According to reports, F6DM adopts electric vehicle system and hybrid power system, which is an advanced technology to control the hybrid power of generator and motor. It not only greatly reduces the fuel consumption and emissions, but also improves the power and handling performance, and realizes a variety of rechargeable and refuelable energy replenishment methods, thus realizing a real dual-power hybrid system.
Wang Chuanfu, president of BYD, said that DM stands for DualMode. If pure electric vehicle is abbreviated as EV and hybrid vehicle is abbreviated as HEV, BYD DM electric vehicle is EV+HEV, in short, it is a rechargeable hybrid vehicle. This system will replace the hybrid electric system and become the most mainstream new energy vehicle system in the world.
Byd electric vehicle charging station
It is reported that BYD dual-mode electric vehicles have applied for more than 700 domestic and foreign patents. After various tests, the vehicle can basically run in pure electric state under urban road conditions. It takes 50% of the power to charge quickly at BYD electric vehicle charging station 10 minute, and it takes only 9 hours to charge slowly at home with ordinary sockets. According to reports, the current cost of the entire dual-mode electric vehicle system is 50,000 yuan, which can be greatly reduced after the output is improved. It is expected that the car will be mass-produced in the second half of 2008.
The invention of iron battery and the expansion of "nuclear power"
It is understood that BYD, as the battery giant with the largest market share in the world, has been expanding at a double rate every year since its establishment in 10, from a capital of 2.5 million to a market value of 30 billion, from a single battery production to a diversified integrated supplier of mobile phone parts that plays an important role in the world mobile phone industry, from a "layman" who manufactures and sells cars to a sales volume of 654.38+million vehicles by producing a single model f 3.
Insiders pointed out that BYD cut into the automobile industry five years ago, which enabled the company to achieve strong development. The mature commercialization of iron batteries means that BYD's battery IT industry and automobile industry have achieved seamless integration and docking, and the strategic intersection of the two industries will undoubtedly provide a strong impetus for BYD's subsequent development.
As an innovative achievement in the automotive field, Wang Chuanfu is full of confidence in the prospect of BYD dual-mode electric vehicles. He said that after dual-mode electric vehicles are put on the market next year, pure electric vehicles will also be put on the market in 2009. In addition to driving the industrial chain of electric vehicles, BYD also plans to push iron batteries into digital industrial chains such as notebook computers, digital cameras and digital walkman. Wang Chuanfu said that the current technology is not the main obstacle, mainly because the voltage of traditional lithium batteries is 3.7 volts, which is slightly higher than that of iron batteries. Once the voltage problem is solved, this new battery is undoubtedly the best substitute for lithium batteries, and the market prospect is immeasurable.
