How to solve the contradiction between the performance and cost of lithium-ion battery materials? As we all know, all lithium-electric materials are facing the same problem as lithium iron phosphate, that is, how to deal with function and cost. In the face of this hostility, experts have accumulated the research methods of nanomaterials and related experiences, so that we have the advantages and characteristics of nano-electrode materials. We can spread the programming concepts and preparatory techniques of the past nanomaterials to the discussion and development of nanomaterials, and simplify the synthesis process.

We should develop materials with low cost and product quality. In fact, there are many successful transformations in recent years. Cui is the professor of Stanford University, at the forefront of nanomaterials and nanotechnology, now he has learned the nanoscale electrode material for lithium-ion batteries, and has announced his research results in the world's leading magazine, such as successful Made of silicon carbon negative knot.

The volume of this new battery is 10 times that of existing lithium-ion batteries. In China, the research of nanomaterials has a good research direction. In the combination of nano and lithium, we always fully confident and enthusiasm.

At first, the laboratory experts chose new materials for lithium iron phosphate and graphene, as their research guide. After two years of continuous efforts, the small test from the laboratory non-metal sintering furnace is experienced to 100 kg of the current powder dynamic heating furnace. The lithium iron phosphate material is converted into a true nanomaterial, and the particle size is controlled at 100 nanometers.

No new new promotion cost. For graphene materials, we have developed a new way to end high-sized manufacturing of high-conductive graphene. Through our way, the processing cost of the expanded graphene material can be reduced to 790 yuan / kg (initial budget), making the large-scale application of graphene become a reality.

At present, scientific research on lithium iron phosphate and graphene is in full swing, it is not simple in it. Byadi wrote the myth of my country's startups. A vice president of the company explained their successful philosophy: We never afraid of core skills.

Others have, I dare to do; someone is not, I dare to think. BYD has problems at every stage, we will say,‘You can't solve it, not because you lack talents, but because you lack your courage.’Official notice! New energy dynamic lithium-ion battery is in fact, the most important research and development policy of power lithium-ion batteries is high energy density, high power characteristics, high security and low cost (or long life).

Therefore, a team studies that the lithium ion battery is meaningless, because the lithium ion battery cannot appear on high-and-use nanoscale electrodes. Although the test line after the lithium iron phosphate nanomaterials after the swivel, the test line is superior, but due to the high processing cost, the price of lithium iron phosphate nanomaterials is once more than 300,000 yuan / ton, which limits its large-scale application. Although most manufacturers claim to have independent intellectual property rights, almost all products are not real nano, the important particle size is usually 200-300 nm.

Therefore, the electrochemical performance data of iron phosphate phosphate is relatively poor, and the processed power lithium-ion battery is far from satisfying the requirements of electric vehicles. This processing cost of this quasi-nanophosphate is naturally low (generally 7-80,000 yuan / ton), the price is generally 12-15 million yuan / ton to ensure profit. In fact, even if it is 10 yuan / ton, it is unacceptable for car power lithium-ion batteries.

Many experts and companies believe that when the price of lithium iron phosphate fell to 7-80,000 yuan / ton or less, lithium iron phosphate power lithium ion battery may be widely used. For this reason, there is still a huge competition between the utility and the price of lithium iron phosphate. In addition, intermittent commonality of lithium iron phosphate has always been a problem that is difficult to solve, bringing a lot of difficulties to battery design, affecting battery equipment and applications.
