Analyze the development prospects and trends of power lithium batteries

The development prospects of power lithium batteriesAccording to the 2008-2010 my country's new energy automobile industry analysis and investment consulting report, according to my country's energy resources and the development trend of international automobile technology, it is estimated that by 2012, the annual output will reach 1 million vehicles in the new energy industry. Energy, it is estimated that by 2025, my country's passenger vehicle ownership of ordinary gasoline vehicles will only account for about 50%, and advanced diesel, natural gas, automobiles, biofuels and other new energy vehicles will develop rapidly. In the future, it will be impossible to prevent the replacement of traditional cars by new energy vehicles. As the heart of new energy vehicles, lithium batteries will have huge industrial and economic benefits, and they will be a huge commercial cake for battery raw material suppliers and manufacturers. It is estimated that by 2012, the annual output of new energy vehicles will reach 1 million. According to the battery cost of 70,000 yuan per new energy vehicle, the lithium iron phosphate material for the positive electrode of the power lithium battery is 52 kilograms, the negative electrode material is 41 kilograms, and the electrolyte is 40 kilograms. One million hybrid vehicles will have a demand for 52,000 tons of cathode materials, 41,000 tons of anode materials and 40,000 tons of electrolytes. For domestic battery manufacturers, this will be a cake with a total output of 70 billion yuan. In terms of passenger cars, this number is three times higher. Hybrid buses require four times as much batteries as cars. Lithium batteries were once considered suitable for the latter two situations, but in the first phase of the National Landscape Library Demonstration Project invested by the State Grid, the bid for an 18 MW lithium iron phosphate battery energy storage system was suspended. The reason is that the cost is too high, and when the battery of the mobile phone is enlarged hundreds of times, the problem of battery consistency still exists. In the large energy storage space, the most popular is the sulfur-containing battery, which has an energy density similar to that of a lithium battery, and there is no consistency problem. Similarly, vanadium batteries, which represent flow batteries, are increasingly considered more suitable for large-scale storage applications. As far as the former is concerned, the State Grid Corporation of China is close to industrialization. The latter represents the company and has become one of the most competitive battery companies in the world through the acquisition of leading foreign technology owners, and has received three rounds of venture capital totaling more than 30 million U.S. dollars. Follow the principle of energy storage: electrical energy and other energy electrical energy. Electrical energy can be converted into chemical energy, potential energy, kinetic energy, electromagnetic energy and other forms of energy storage. Physical energy storage includes pump energy storage, compressed air energy storage and flywheel energy storage. Electromagnetic energy storage includes superconductors, super capacitors and high energy density capacitors. Electrochemical energy storage includes lead-acid battery energy storage, nickel-hydrogen battery energy storage, nickel-cadmium battery energy storage, lithium battery energy storage, sodium-sulfur battery energy storage and liquid flow battery energy storage. Phase change energy storage includes ice energy storage and cold energy storage. With the rapid start of the energy storage market, some traditional energy storage technologies are returning. In early July, Yingli New Energy Chairman Miao Liansheng announced in Hainan that Yingli was developing a new generation of flywheel energy storage. Flywheel energy storage is the process of converting electrical energy into high-speed flywheel kinetic energy, and using the flywheel generator to generate electricity when needed. In the 1990s, it was used in power storage tests in Japan and the United States, but it has not yet been used on a large scale. The renewed attention of the flywheel is due to the use of high-temperature superconductors to achieve a breakthrough in magnetic suspension. This makes it possible for magnetic bearings to eliminate friction losses; secondly, the emergence of high-strength materials such as carbon fiber enables the flywheel to rotate at a higher speed, which can store more energy. Phase change energy storage has a broader application prospect for building energy conservation. Buildings in our country consume more than 30% of energy. Phase change energy storage, such as ice storage, cannot store electricity, but can regulate heat. Combined with passive energy-saving technology, it can solve the problem of building energy-saving on a large scale and at low cost. For our country, this is a more cost-effective way to save energy and reduce emissions than electric vehicles. In places like Shanghai where low-carbon economic planning is restrained and reasonable, building energy efficiency is receiving government support. Obviously, there are many opportunities for phase change energy storage. Statement: Some pictures and content of articles published on this site are from the Internet.
