How to solve the contradiction between the performance and cost of lithium battery materials? As we all know, in the issue of electrode capacity, all lithium battery materials face the same problem as lithium iron phosphate, that is, how to deal with the hostility between function and cost. In the face of this hostility, experts have accumulated research methods and relevant experience of nanomaterials, so that we have the advantages and characteristics of nanoelectrode materials. We can easily extend the programming concepts and preparation techniques of nanomaterials to the discussion and development of nanomaterials, and simplify the synthesis process. We should develop a material with low cost and stable product quality. In fact, there have been many successful changes in recent years. Cui is a professor at Stanford University. He is at the forefront of nanomaterials and nanotechnology. Now he knows about nanoscale electrode materials for lithium batteries and has published his research results in the world's leading magazines, such as successful manufacturing A silicon-carbon negative sintering line. The volume of this new type of battery is 10 times that of the existing lithium battery. In China, the research of nanomaterials has a very good research direction. In the combination of nano and lithium, we are always full of confidence and enthusiasm. At first, the experts in the laboratory chose lithium iron phosphate and graphene, two new materials in today's material world, as their research guide. After two years of continuous hard work, we have gone through a small-scale test of a non-metallic sintering furnace in the laboratory to a pilot test of 100 kg of the current powder dynamic heating furnace. The lithium iron phosphate material is transformed into a real nano material, and the particle size is controlled at 100 nanometers. No additional processing costs. Regarding graphene materials, we have developed a new method to end the large-scale manufacturing of highly conductive graphene. Through our method, the processing cost of expanded graphene materials can be reduced to 790 yuan/kg (initial budget value), making the large-scale application of graphene a reality. At present, scientific research on lithium iron phosphate and graphene is in full swing, and it is not easy to have a place in it. BYD wrote down the myth of a start-up company in my country, and a vice president of the company explained their philosophy of success: We are never afraid of core skills. If others have it, I dare to do it; if others don’t, I dare to think. BYD has problems at every stage. We will say,'You can't solve it, not because of your lack of talent, but because of your lack of courage. 'Official announcement! The latest development of new energy power lithium-ion batteries In fact, the most important research and development policies for power lithium batteries are high energy density, high power characteristics, high safety and low cost (or long life). Therefore, it is meaningless for a team to study lithium batteries, because lithium batteries cannot display data on highly practical nano-scale electrodes. Although the test line of lithium iron phosphate nanomaterials after the sintering machine rotary kiln is superior after all, due to the high processing cost, the price of lithium iron phosphate nanomaterials once exceeded 300,000 yuan/ton, which restricted its large-scale application. Although most manufacturers claim to have independent intellectual property rights, almost all products are not truly nanometer, and the important particle size is usually 200-300 nanometers. Therefore, the electrochemical performance data of domestic lithium iron phosphate is relatively poor, and the processed power lithium-ion battery is far from meeting the requirements of electric vehicles. The processing cost of this kind of quasi-nano lithium iron phosphate is naturally low (generally 70-80,000 yuan/ton), and the price is generally 120,000-150,000 yuan/ton to ensure profit. In fact, even the price of 10 yuan/ton is unacceptable for automobile power lithium-ion batteries. Many experts and companies believe that when the price of lithium iron phosphate materials drops to 70,000-80,000 yuan/ton or lower, lithium iron phosphate power lithium-ion batteries may be widely used. For this reason, there is still huge competition between the utility and price of lithium iron phosphate. In addition, the intermittent common properties of lithium iron phosphate has always been a difficult problem to solve, which brings great difficulties to battery design and affects battery equipment and applications.
