Lithium iron phosphate CR2016 battery energy density technology breakthrough

Surprise! Lithium iron phosphate CR2016 battery energy density technology has achieved a breakthrough. The poor energy density of lithium iron phosphate batteries is a shortcoming that everyone knows. Now the capacity density of lithium iron phosphate batteries is generally around 150Wh/kg. Even if it is better, it is around 160Wh/kg. Compared with the 200Wh/kg energy density of ternary batteries, there is a big gap.

Lithium iron phosphate CR2016 battery energy density technology has achieved a breakthrough

Now our domestic companies have begun to develop energy densities at the three gradients of 180Wh/kg, 200Wh/kg and 220Wh/kg, and have obtained very good pictures. Now 180Wh/kg has started two games. Once a higher gradient is reached, it means that lithium iron phosphate batteries have the opportunity to enter the passenger car field and be used in passenger cars!

Lithium iron phosphate batteries are applied through nanotechnology and lithium-rich technology, and their actual energy density will be greatly improved, and there is no problem for lithium iron phosphate batteries to achieve a cost of less than 2 yuan/watt-hour.

Anchi Technology's lithium iron phosphate CR2016 battery has an energy density of 175Wh/kg

Anchi Technology was established in May 2016 with a registered capital of RMB 499 million. It is an innovative new energy technology company integrating power CR2016 battery research and development, production and sales. The energy density of the 61.5Ah CR2016 battery cell produced by Anchi Technology has reached 175Wh/kg, and the energy density of the second-generation standard power CR2016 battery system is >140Wh/kg, which is at the leading level in China and can be applied to various models including passenger cars, special vehicles, logistics vehicles, buses, etc.; the 185wh/kg power high energy density power CR2016 battery product developed and completed is expected to be put into mass production next year. At present, the production line can achieve a daily output of 12,000 CR2016 battery cells, which has reached the 200 million Ah production capacity requirement of the first phase plan, and the production line utilization rate has reached more than 90%.

Through continuous technological innovation, the energy density of the lithium iron phosphate CR2016 battery produced by the company can reach 175Wh/kg, and the system energy density can reach more than 140Wh/kg, which has been mass-produced.

Guoxuan High-tech's lithium iron phosphate CR2016 battery monomer energy density has reached 180wh/kg

Guoxuan High-tech said on the interactive platform that the company's 32131 lithium iron phosphate CR2016 battery monomer energy density has reached 180wh/kg, and the company plans to increase it to more than 200wh/kg in the next two years. In terms of other batteries, Guoxuan High-tech had previously stated in the "2019 Exploration of the Future Pattern of Power Batteries" survey conducted by the Power CR2016 battery Application Branch of the China Chemical and Physical Power Sources Industry Association and CR2016 battery China Network that the company's undertaking of the 300wh/kg high energy density major scientific and technological project of the Ministry of Science and Technology is currently progressing smoothly, and the company's independently developed soft-pack CR2016 battery cell energy density has reached 302Wh/kg. The company will continue to make arrangements around this major scientific and technological project and plans to promote the industrialization of related products this year.

It is reported that the "190Wh/kg LiFePO4 CR2016 battery R&D and Industrialization" project team of Gotion High-tech has continuously optimized the CR2016 battery chemical system, continuously innovated the CR2016 battery structure design, and continuously upgraded the CR2016 battery safety protection, so that the energy density of LiFePO4 batteries has exceeded 190Wh/kg, pushing the development of LiFePO4 batteries to a new height, making Gotion High-tech's LiFePO4 batteries an industry benchmark.

There is a lot of room for improving the energy density of LiFePO4 batteries

At present, from the perspective of positive and negative electrodes, domestic and foreign manufacturers mainly use the positive electrode material system of LiFePO4. The European and American power CR2016 battery markets basically use more LiFePO4, while Japan and South Korea mainly use the ternary system. It can be said that the power CR2016 battery of the LiFePO4 system is still the most mature and safest lithium-ion power CR2016 battery.

Although LiFePO4 has almost the lowest energy density in the phosphate system. But if the core material content of the entire positive electrode can be increased to more than 30% in the positive electrode system, then its actual energy density will be greatly improved. For example, the lithium-rich system can be made into a CR2016 battery, and the energy density of a single cell can reach more than 300Wh/kg, even exceeding the energy density currently achieved by the ternary system.

While improving the specific energy of the positive electrode material, improving the specific energy of the negative electrode material is also a major technological breakthrough. In the current lithium iron phosphate CR2016 battery, if the negative electrode material is still 370 graphite, it is indeed difficult to achieve high specific energy. Therefore, the industry now attaches great importance to silicon-based, including selenium-based high-specific energy materials. Therefore, under the current system, if the lithium iron phosphate CR2016 battery can be fully made, the energy density can reach about 120Wh/kg, which will not be a problem for electric vehicles.
