On the afternoon of April 15, the R&D team of Changzhou Lithium Source New Energy, a subsidiary of Lopal Technology, announced in Nanjing that the company has made a revolutionary technological breakthrough, and its latest successful new spherical lithium iron phosphate product - "Lithium Iron No. 1" will greatly improve the performance of lithium iron phosphate battery cathode materials in low temperature environments, while significantly improving the charging rate.
Lithium battery is the "heart" of new energy vehicles, and cathode material is the core material in the lithium battery of new energy vehicles, which currently accounts for more than 50% of the total cost of the battery, mainly divided into two types: lithium iron phosphate cathode material and ternary cathode material. Lithium iron phosphate cathode material has become the mainstream choice of major new energy vehicle manufacturers in the market due to its relatively lower price and better safety performance. For example, by BYD released the "blade battery" two years ago, the cathode material used is lithium iron phosphate, and many of 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 under low temperature conditions the mileage will be greatly reduced, for example, some popular electric vehicle models on the market, the actual mileage in the winter minus 20 degrees conditions, often only less than 50% of the official mileage, because of this, the penetration rate of new energy vehicles in the northern market has been poor. In 2021, among the top 30 cities in the national sales of new energy vehicles, only Beijing, Tianjin, Luoyang and Taiyuan are the four northern cities.
The new spherical "black technology" lithium iron phosphate product successfully developed by lithium source company - "lithium iron no. 1" is a new generation of lithium iron phosphate products that have been invented by more than 20 R&D experts of its Shenzhen Research Institute for 8 years and after more than 2,000 repeated experiments, and its performance is a revolutionary technological breakthrough for the new energy automobile lithium battery industry. By establishing a high-speed lithium ion transmission channel inside the cathode material, "Iron Lithium No. 1" realizes that the discharge capacity retention rate of lithium iron phosphate materials can be increased from 55% to 85% at -20 degrees, and the discharge capacity retention rate at -40 degrees Celsius can be increased from near zero to 57%.
Not only that, "lithium iron 1" also has excellent fast charging performance, according to estimates, conventional lithium iron phosphate batteries need to be charged quickly for 40 minutes to achieve a cruising range of about 550 kilometers; and the lithium iron phosphate battery using "lithium iron 1" material, only need to be charged for 15 minutes, you can reach a cruising range of 500 kilometers.
At present, the product has obtained five national patents, and has achieved product matching with some domestic battery manufacturers, and is currently in a hot selling situation of short supply. Shi Junfeng, chairman of Lopal Technology, said that in the next step, Lopal Technology, a lithium source holding company, will use the advantages of its listed enterprises' main engine factory customers to promote this new lithium iron phosphate cathode material product to major car companies, so that this "black technology" new technology can benefit more new energy vehicle users.
