The research and development team of Changzhou Lithium Source New Energy, an enterprise owned by listed company Longyi Technology, announced in Nanjing on the afternoon of the 15th that the enterprise had made a revolutionary technological breakthrough. their newly developed new spherical lithium iron phosphate product, "Iron Lithium No. 1", will greatly improve the performance of lithium iron phosphate battery cathode materials at low temperatures and significantly increase the charging rate.
Lithium battery is the "heart" of new energy vehicles, and cathode materials are the core materials of lithium batteries for new energy vehicles, accounting for more than 50% of the total cost of batteries. They are mainly divided into two types: lithium iron phosphate cathode materials and ternary cathode materials. Lithium iron phosphate cathode material has become the mainstream choice of major new energy vehicle manufacturers in the market because of its relatively lower price and better safety performance. For example, BYD released the "blade battery" two years ago, which uses lithium iron phosphate as the cathode material. Tesla's current models are also equipped with lithium iron phosphate batteries. However, conventional lithium iron phosphate cathode materials also have their own obvious shortcomings, mainly the mileage at low temperatures will be greatly reduced, such as some popular electric models on the market, the actual mileage at minus 20 degrees in winter is often less than 50% of the official mileage, which is why the penetration of new energy vehicles in the northern market has been poor. In 2021, among the top 30 cities in terms of sales of new energy vehicles in China, only Beijing, Tianjin, Luoyang and Taiyuan are the four northern cities.
Liyuan No. 1, a new spherical "cool techs" lithium iron phosphate product successfully developed by Liyuan Company, was successfully developed by more than 20 R & D experts from its Shenzhen Research Institute for eight years and after more than 2000 repeated experiments. finally invented a new generation of lithium iron phosphate product, its performance can be called a revolutionary technological breakthrough for the lithium battery industry of new energy vehicles. By establishing a high-speed lithium ion transport channel inside the cathode material, "Iron Lithium 1" can increase the discharge capacity retention of lithium iron phosphate from 55% to 85% at-20 degrees. The discharge capacity retention at-40 degrees is increased from close to zero to 57%.
Not only that, "Iron Lithium 1" also has excellent fast charging performance. It is estimated that conventional lithium iron phosphate batteries need to be quickly recharged for 40 minutes to achieve a range of about 550 kilometers, while lithium iron phosphate batteries made of "iron lithium 1" material can achieve a range of 500 kilometers with only 15 minutes of fast charging.
At present, the product has obtained five national patents, and has achieved matching products with some domestic battery manufacturers, and is currently in a hot-selling situation that supply exceeds demand. Shi Junfeng, chairman of Longyi Technology, said that in the next step, Lithium Source holding Company Longyi Technology will take advantage of the supporting advantages of its listed companies' mainframe factory customers to promote this new lithium iron phosphate cathode material product to major car companies, so that this new "cool techs" technology will benefit more new energy vehicle users.
According to the reporter's understanding, Longyi Technology is headquartered in Nanjing Economic and technological Development Zone. Last year, its overall sales exceeded 4 billion yuan, an increase of 112 percent over the same period last year. Among them, the sales volume of lithium iron phosphate cathode materials from Changzhou Lithium Source reached 1.877 billion yuan, accounting for 46.3 percent of the overall sales of Longyi Technology. It is worth mentioning that on April 13, the "Zeping Macro" research team led by famous economist Ren Zeping also released a research report entitled "Invisible Champion National Brand Power New Energy" for Longpan Science and Technology, believing that with the release of production capacity in the future, the contribution of green energy business income such as lithium battery cathode materials under Longpan will be greatly increased.
