Development of the world’s power batteries
The battery is currently no applications to large scale and the automotive industry, and as the era of fair trade in dual DM2007 BYD’s-vehicle systems in electric mode apparently cell technology to power began to penetrate the attention people. Battery Categories
So what exactly is the driving force for the development of what has happened, we must first look at the common category of existing Dell Latitude D520 battery.
Lithium-iron battery
Lithium-iron battery full name is lithium iron phosphate, lithium batteries and lithium-ion batteries in the 20th century developed a new battery of high energy. This battery is a lithium metal anode, the cathode with MnO2, SOCl2 (CFX) n and so on. 70 years in practical use. Because of its high energy, battery voltage high operating temperature, long shelf life, etc., has been widely used in military aircraft and civilian small, such as mobile phones, laptops, camcorders, cameras and so on, partly to replace the traditional batteries.
Lithium-ion batteries for its unique advantages in performance portable devices such as laptops, cameras, mobile communications are universally applied. At present the development of high capacity lithium-ion VGP-BPS9 batteries in electric vehicle to begin a trial, which should become the 21st century, the power of electric vehicles, one of the engines of change, and a satellite, Aerospace and storage aspects of the energy applied.
High-iron battery
High-iron battery is a synthesis of a stable ferrate (K2FeO4, BaFeO4, etc.) may be used as cathode materials for battery rail at high speed to produce the energy density, small size, weight Lightweight, long life, clean new chemical batteries.
High-benefit of iron battery:
High energy capacity. Currently on the market that the battery power only 60 civil - 135w/kg and the battery can achieve high iron 1000w/kg above battery discharge current average is 3-10 times more. Particularly good choice for high power and at high current. High-cost battery iron efficiently. Alkaline manganese batteries can not meet the current need for high power capacity, high current digital cameras, video cameras and other electronic products, the needs of lithium-ion batteries because of the costs in this area do not have d a strong competitive advantage.
Flat-curve of the iron hp Pavilion dv4000 battery discharge. Such as Zn-K2FeO4 Plastics Industry Network All rights reserved more than 70% of the time of discharge in the 1.2-1.5V.
Rich in raw materials. The most abundant element in the crust for aluminum and iron content of iron in the crust to 4.75%, manganese content of 0.088%. In addition, each 6 mol Valent Iron can produce 3mol electronics, while the price of manganese per mol + 4 can only produce 1mol electronics, the dosage of iron is very rich in its own situation, only 1 Mn / 3 of a ghost know that significant savings in social resources and lower raw material costs. MnO2 on the market about 9,000 yuan per tonne, Fe (NO3) 3 about 7,500 yuan / ton. Non-polluting green. After unloading of product for ferrate FeOOH or Fe2O3-H2O, non-toxic pollution, ecological, does not require recycling.
Power battery status
The base power Electric Vehicle - Battery has been a shift binding manufacturers of electric cars in bottlenecks on the world automotive industry. Is the current internationally recognized high iron and lithium iron phosphate. High-iron toshiba PA3465U-1BRS battery has been considered as restricted area of industrial automation networks, lithium iron phosphate is the subject of research and development of domestic and foreign firms. Ferrate as battery materials developed by Israeli researchers published in the journal Science. However, the aqueous solution with the performance of the storage battery that bad, there are many national universities in the study.
In 1997, material lithium iron phosphate has begun to attract national attention. In 1998, the state 863 plans to invest 2 billion lithium iron phosphate in the study of Shantou. Chinese companies have been launched since 2001, lithium iron phosphate development, after six years, the first university finals in 2007, the lithium iron phosphate breakthrough technology from the laboratory to pilot the technology for producing a series of technical and engineering ZAOCHE168.com Copyright all, and to improve related processes, which makes the lithium iron phosphate security has been a greater degree of improvement and to ensure that iron provided lithium serialization products phosphate and wide industrial base.
In a few years ago, BYD 500 R & D team, the organization has begun the search for iron battery research and development. After tens of thousands of trials and tests, BYD has successfully developed a dedicated iron battery electric vehicles, the network processing metals All Rights Reserved called “AND-POWER”. BYD person in charge that represents BYD VGP-BPS10A battery on the latest scientific research, in which I said that protecting the environment and energy (electricity and environment), T indicates the technology (technology), power said power and average energy, in BYD “ET-Power” to name the new vehicle www.GUIZHIDAO.com Power Technology, intended to take the future of science and technology, the future of automotive resources. In fact, the main component of this battery is lithium iron phosphate, which is safe, stable, the high capacity, environmentally friendly, cheap, etc., but there are also low electrical conductivity, density, gaps low vibration. Lithium iron phosphate is so late, there is no reason for a wide range of applications, the electrical conductivity of poor quality is a major problem. This problem can be solved now is to add C or other conductive agent. This industry is regarded as a limited part of the high-iron battery.
Battery for future development
As energy shortages in the world and increased regulation of vehicle exhaust emissions, new energy power is the inevitable trend of development, this cell cars is the trend of energy, but for technical reasons, these forms of traction batteries are just BYD large-scale applications in the market. It was reported that in 2009, BYD will launch a full car battery, if all battery-powered cars can be fully applied to the market, it would be a revolution in the energy market, either from the environmental or consumer spending on the cost side, are of great advantage.
Batteries power of tomorrow will be the focus of research of various automakers and direction of development for the large car market in the world is there a huge market potential.
