What's so great about BYD's iron batteries?

China's lever to pry the world appeared, so good news exceptionally should be included in my blog. The technical data listed below shows that the energy density of high iron batteries can reach more than 1000w/kg, and the discharge current is 3-10 times higher than that of ordinary batteries. The discharge curve of high iron battery is flat, more than 70% of the discharge time is 1.2-1.5 V. Raw material is abundant and low cost, green and non-polluting, no need to recycle. Rapid charging can reach 50% power in 10 minutes, and it takes only 9 hours to fully charge the battery at home by slow charging with ordinary socket. I see such data is very excited, the emergence of such batteries is enough to subvert the current automotive industry and even the energy industry, it is no exaggeration to say that it is an outpost of the energy revolution, the author of the "zero greenhouse gas emissions and electric vehicles" article has a detailed discussion, and to the central government to put forward a proposal to strongly urge the formation of a national power company Specializing in battery manufacturing, leasing, the implementation of all such and specifications of the battery national monopoly and recycling system. Here we can imagine, a set of 2-4 tons of batteries, with specially designed constant power torque transmission motor, no transmission, in the 99 tanks can at least bring 10 tons of materials and ammunition weapons, with a 20-40 tons of carriers to transport batteries, haha the old rice only bowed down, it is really out of the children of China more than the will of the strange! The company's business is a new one, and it's a new one.

China changed the world BYD iron battery mass production

At present, the power supply of digital cameras is basically based on lithium-ion rechargeable batteries. Lithium-ion batteries have a large capacity, light weight, no memory effect and other advantages, but lithium-ion batteries also have many shortcomings, the most prominent is the poor security, short circuit, heat and so on are prone to explosion, battery explosion injury reports are often seen in the press. Secondly, although the capacity of the "big" but not enough to meet the pixel is getting higher and higher, the LCD is getting bigger and bigger, the video function is getting stronger and stronger of the development of the digital camera needs, people generally look forward to better performance of the battery came out.

In the past, people focused on fuel cells, but because the technology is too complex, in terms of miniaturization, safety, fuel cells still have a long way to go. And a few days ago about BYD's new energy car reports caused worrying concern: this new battery in many ways than lithium-ion batteries are much better than the practicality, much closer than the fuel cell, is expected to be in the near future for the hands of the digital camera in our hands to provide a constant flow of energy. What's exciting is that BYD is firmly on the world's leading edge of research into the application of iron batteries, an area in which China will once again change the world.

What is an iron battery

Currently, there are two types of iron batteries researched at home and abroad: high-iron and lithium-iron, and BYD's iron batteries seem to be the former, and except for BYD no other manufacturer has yet claimed that its products can be practical on a large scale.

High iron battery is to synthesize stable ferricyanide (K2FeO4, BaFeO4, etc.), which can be used as the cathode material of high iron batteries to make new chemical batteries with high energy density, small size, light weight, long life and no pollution.

Advantages of iron batteries:

High energy and high capacity. The specific power of civil batteries on the market is only 60-135w/kg, while high 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 high current. The cost performance of high iron battery is high. Alkaline-manganese batteries can not meet the current need for high-current, high-capacity power digital cameras, cameras and other electronic products, lithium-ion batteries due to the cost of this area does not have a strong competitive edge.

Flat discharge curve of high iron battery. Such as Zn-K2FeO4, more than 70% of the discharge time at 1.2-1.5V.

Raw materials are abundant. The most abundant elements in the earth's crust are aluminum and iron, iron content in the earth's crust is 4.75%, manganese content is 0.088%. At the same time, every mol +6 iron can produce 3 mol electrons, while every mol +4 manganese can only produce 1 mol electrons, the dosage of iron is only 1/3 of manganese in the case of its own richness, which greatly saves the social resources and reduces the cost of raw materials. In the market, MnO2 is about 9000RMB/per ton, and Fe(NO3)3 is about 7500RMB/per ton.

Green and non-polluting. The product after the discharge of perovskite is FeOOH or Fe2O3-H2O, which is non-toxic, non-polluting and friendly to the environment. No need to recycle.

Domestic batteries have finally ushered in the capital market, "Open Sesame" moment.

September, Shenzhen BYD Group's latest patented technology "iron battery", market operation into the countdown stage. If successfully applied, it would mean that the battery maker, which ranks second in the world in rechargeable battery production, would turn the automotive world upside down, realizing four-wheel drive and infinitely variable speeds for electric vehicles.

Despite the skepticism from the outside world, the industry's foreign-funded giants still don't dare to underestimate it. The reason is, "BYD has relied on independent research and development, breaking through the battery industry monopoly caused by the 'forbidden zone', strong will be the former high-priced cell phone battery from the 'price' of thousands of dollars, all the way down to the current dozens of dollars! 'affordable', so that cell phones gradually from aristocratic consumption to civilian consumption."

Japan's lithium-ion power battery project in China, R & D Commissioner Shirai Kunio, more than once in public occasions to issue the above sentiment. He told reporters that from the 1980s, Japan's Fuji, Toshiba, Panasonic and other manufacturers began to research and production of disposable alkaline batteries, to the late 1980s and early 1990s, Japan's disposable batteries to enter the Chinese market, looking for OEMs to start, he has been concerned about the consumer market in China. "During this period, a large number of disposable batteries were needed for both the popular beepers and the portable radios, alarm clocks and miniature flashlights that are still in use today. Although Chinese battery producers such as Shuanglu, Nanfu and White Elephant appeared at that time for mass production of disposable batteries, the long-term output was large and the production value was low. This can be illustrated that the domestic battery at that time has been in the downstream of the industrial chain due to the lack of core technology."

What Hisao Shirai didn't expect was that just 10 years later, the domestic battery brand developed disposable batteries with independent intellectual property rights - in 2004, Shuanglu Battery began to embark on the National Torch Program project, namely, the research and development of the LR6 alkaline digital king batteries. At present, its alkaline battery products have also been developed from one item, LR6, to 12 series, such as LR20, ZR6 and ZR03, basically covering all alkaline battery product lines. "Reflected in the consumer market, Japanese, European and American brand batteries are shrinking in the domestic market, while Chinese brands are gradually entering the overseas market."

Also confirming the change to the reporter was Liu Guoen, chief editor of a Beijing-based technology Web site. He defined this period as the first watershed in the development of domestic batteries. "This is the stage when domestic batteries sacrificed the market for technology, and at the same time, it is also the secret of the rapid development of many domestic battery companies." Since then, the China Battery Industry Association in 2005 for the first time officially released the "hydrogen-nickel battery product quality market to buy samples of comparative test results" also shows that, whether it is the performance or price, Nanfu, Double Deer and other domestic brands of batteries are significantly more than the old Nissan batteries.

And in fact, the benefits are obvious. In 2003, Global Sources (GlobalSourcesLtd.) published a market information report titled "China's Battery Supplier Production Capacity". The report noted that China is a recognized producer of primary batteries with an annual production of 19 billion cells. The industry's average annual value exceeds US$4 billion. The number of battery manufacturers in the region is estimated at more than 2,000, of which 300 produce products for export. Finally, the report predicts that "China is now the world's largest market for the supply of non-rechargeable batteries, while it will soon become a leading producer of rechargeable batteries as well."

As it says. Soon, with the introduction of rechargeable secondary batteries, domestically produced batteries came to a second watershed. "At the beginning of this stage, there was not yet a single company in China that could produce secondary batteries. At that time, the global secondary battery field, whether nickel-chromium-cadmium, nickel-zinc-hydrogen and lithium batteries, were monopolized by a few Japanese companies." Liu Guoen said, "However, domestic battery companies rely on independent research and development, and ultimately break through the industry monopoly of Japanese companies, strong secondary battery high body price, all the way down to the stage of parity."

Meanwhile, domestic secondary battery producers have completed the original accumulation. Until around 1998, a price of 30,000 yuan "big brother", a Japanese-made nickel-cadmium battery to sell more than 1,000 yuan. But domestic batteries made, even if sold 600 yuan a piece, plus the cost of repair, profit is still 50% -60%, profit space is very substantial. Xia Zuoquan, founder of BYD, said frankly: "BYD successfully entered the field of cell phone batteries in just a few years, not only to break the monopoly of the Japanese companies, but also very profitable."

As one of the direct results of this innovation, inexpensive domestic batteries in the consumer market to quickly realize the diversification of applications. "Cell phones, laptops, MP3s, digital cameras ...... almost any digital product you can think of, can't play at all without batteries." Liu Guoen is pleased to say that batteries are also used in industrial cordless equipment, backup power, military and medical markets.

Meanwhile, cell phones, notebook computers, Bluetooth headsets, cellular phones, mobile DVDs and other appliances are all moving toward portability. All of this has made thin and light batteries with small size popular.

Let Shirai Hisao lamented that the development of secondary batteries in China, just less than 10 years. Irish ResearchandMarkets released lithium battery market forecasts also show that China's current production of large lithium batteries (disposable and rechargeable batteries) is the world's largest. In the global lithium battery production, China accounted for 23.8%.

And, the domestic battery on the development of the idea of much more than that. 1997, nine ministries and commissions jointly launched the "on the limitation of mercury content in battery products". Aimed at through the policy baton, in the production source to take the lead in high standards and strict requirements, and then drive market consumption, so as to realize the popularity of environmentally friendly energy-saving batteries.

In fact, the domestic battery companies began to take the lead in research and development of environmentally friendly batteries before the promulgation of the policy. 2000, Nanfu battery to achieve a full range of alkaline batteries, "non-mercury, cadmium-free, lead-free," the production of environmentally friendly. Since then, many large domestic battery companies have also begun to transform the production of environmentally friendly and energy-saving alkaline batteries, which led to the domestic production of alkaline batteries. It is understood that in 1995 when the first batch of environmentally friendly batteries were introduced, the entire production of alkaline batteries is more than 1 billion, has now grown to 6 billion -7 billion. Since last August, by the National Light Industry Battery Quality Supervision and Testing Center for special testing, Nanfu, 555 and other 11 leading enterprises alkaline manganese batteries mercury content has been lower than the mercury content of non-mercury batteries limited indicators.

The first dual-mode "iron electric" car F6 is expected to be listed next year

High Fair curtains have not yet opened, the new scientific and technological breakthroughs are frequently heard. Yesterday (10th), BYD released the world's first iron battery at the Convention and Exhibition Center, and announced that the iron battery has matured into a commercial vehicle - the F6, a dual-mode hybrid electric vehicle powered by an iron battery, is expected to hit the market in 2008.

According to the introduction, BYD's iron battery is far superior to lithium batteries in the three core indicators of "high capacity requirement", "high safety requirement" and "low cost requirement". Lithium batteries, which is not only expected to bring out an electric vehicle industry chain for Shenzhen, is also expected to become the future of laptop computers, cell phones, electric toys in the energy alternatives.

BYD's iron batteries for the first time to realize the mature commercial

It is understood that, compared with the traditional nickel-metal hydride batteries and lithium batteries, BYD developed iron batteries have inherent advantages: the world's abundant iron resources, iron is cheaper than nickel, lithium metal, coupled with its environmentally friendly, will not cause such as nickel-metal hydride batteries and lithium batteries discarded by the pollution generated.

As early as a few years ago, BYD organized a 500-person R&D team to begin the research and development of iron batteries. After tens of thousands of trials 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 the latest scientific research achievements of BYD in the field of batteries, in which E represents environmental protection and electricity (environment and electric), T represents technology (technology), power means power and energy, BYD to "ET-POWER" to the "ET-POWER" for electric vehicles. BYD uses "ET-POWER" to name its new automotive power technology, taking the meaning of future technology and future automotive power.

The BYD F3e equipped with "ET-POWER"

It is understood that "ET-POWER" iron battery voltage of 3.3 volts each, 60 ampere hours, the number of battery charging cycles up to 2000 times or more, the battery's continuous mileage life is greater than 600,000 kilometers. The F6 dual-mode electric vehicle, for example, uses 100 iron batteries, with a driving range of up to 430 kilometers on a full charge (100 kilometers in electric mode + 330 kilometers in hybrid mode), and a maximum speed of up to 160 kilometers per hour.

Compared with the most widely used lithium batteries, BYD's iron batteries are cheaper and more environmentally friendly than lithium batteries, and because of the new design, the battery capacity, cycle life, temperature range, and discharge performance are better than lithium batteries. In addition, due to the use of high thermal stability materials and meticulous process design, the safety and reliability of BYD iron battery is greatly enhanced. Contrary to the explosion phenomenon that may occur in the improper use of lithium batteries, iron batteries are safe and reliable, and will not explode even when thrown in the fire.

First used in BYD dual-mode power car F6

At the press conference, BYD unveiled the world's first dual-mode hybrid car F6DM powered by an iron battery motor and gasoline engine, whose core power battery is the ET-POWER.

According to the introduction, the F6DM adopts the electric vehicle system and hybrid power system, is a control generator and electric motor two kinds of hybrid power combination of advanced technology, not only greatly reduce fuel consumption and emissions, but also improve the power and maneuvering performance, the realization of both charging, but also refueling of a variety of energy supplementation, to achieve the true meaning of the dual-power hybrid system.

Wang Chuanfu, BYD's president, said DM stands for DualMode. If pure electric is abbreviated as EV and hybrid is abbreviated as HEV, then BYD DM electric car is EV + HEV, in short, it is a rechargeable hybrid electric car. This kind of system will replace the oil-electric hybrid system and become the world's most mainstream new energy vehicle system.

BYD EV charging station

It is reported that BYD's dual-mode electric car has declared more than 700 domestic and international patents. The car has gone through a variety of state of the vehicle test, in urban road conditions can basically realize the exercise of pure electric state, in BYD electric car charging station fast charging 10 minutes up to 50% of the power, at home using an ordinary socket slow charging, fully charged only 9 hours. According to reports, the current cost of the entire dual-mode electric car system is 50,000 yuan, the cost can be significantly reduced after the increase in production, it is expected that the car will be mass-produced in the second half of 2008 on the market.

The invention of iron batteries to add expansion "nuclear power"

It is understood that, as the world's largest market share of the battery giant, BYD from 10 years ago to build factories to date, doubling the speed of rapid expansion each year, from the expansion of the capital of 2.5 million to the market value of 30 billion yuan, from the production of a single battery to the world's leading mobile phone industry, diversification of mobile phone production. The cell phone industry pivotal diversified cell phone parts integrated supplier, from making cars, selling cars "layman" to with the production of a single model F3 exceeded 100,000 sales "miracle", BYD only took a very short period of time.

Industry insiders pointed out that BYD cut into the automobile industry 5 years ago, so that the enterprise to obtain strong development, and the iron battery maturity of the commercialization, which means that BYD's two major industries - the battery IT industry and the automobile industry to achieve a seamless integration and docking, the two major industries of the strategic division will undoubtedly provide strong impetus for the subsequent development of BYD! The two industries will undoubtedly provide a strong impetus for BYD's subsequent development.

As an innovation in the automotive field, Wang Chuanfu is full of confidence in the prospect of BYD's dual-mode electric vehicles. He said that after the dual-mode electric car is launched to the market next year, the pure electric car will also be on the market in 2009. In addition to pulling the electric car industry chain, BYD plans to push the iron battery into the digital industry chain of notebook computers, digital cameras, digital walkman and so on. Wang Chuanfu said, the current technology is not the main obstacle, mainly the traditional lithium battery voltage of 3.7 volts, slightly higher than the iron battery 3.3 volts, once the voltage problem, this new battery is undoubtedly the best alternative to lithium batteries, the market outlook is immeasurable.
