Tesla said it plans to use lithium iron phosphate batteries in all standard endurance electric vehicles and transfer battery production closer to the automobile assembly plant < p > < / P > < p > "our goal is to localize all key automotive components," drew Baglino, senior vice president of power systems and energy engineering at Tesla, said on Wednesday's earnings conference call. < / P > < p > he said, "We are working internally with suppliers to achieve this goal, not only at the terminal assembly level, but also at the upstream level as far as possible." < / P > < p > at present, 95% of the world's lithium iron phosphate batteries are produced by companies such as Ningde times. Tesla has used the lithium iron phosphate batteries made by Ningde times in some model 3 and model y electric vehicles made in China, and has begun to sell model 3 electric vehicles equipped with such lithium iron phosphate batteries in the U.S. market. < / P > < p > it is recognized in the industry that lithium iron phosphate batteries are cheaper than nickel based batteries Safer, but with lower energy density, the range of electric vehicles equipped with lithium iron phosphate batteries is less than that of nickel based batteries. < / P > < p > this technology has attracted the interest of many electric vehicle manufacturers. In June this year, it was reported that apple is in preliminary negotiations with Ningde times and BYD to buy lithium iron phosphate batteries for planned electric vehicles and hope that they will be sold in the United States Build a factory. < / P > < p > Craig Irwin, an analyst at Roche capital, said that it may be better for Ningde era to make batteries in China because it can obtain the lowest cost materials in the world. < / P > < p > China is not only the world's largest electric vehicle market, but also dominates the production and supply chain of lithium-ion batteries, including upstream links such as mineral mining and raw material processing. < / P > < p > "At present, only Ningde times and BYD produce lithium iron phosphate batteries," said Taylor Ogan, CEO of snow bull capital, a green and high-tech hedge fund. < / P > < p > last year, Elon Musk, CEO of Tesla Said Tesla will use lithium iron phosphate batteries on Model 3 electric vehicles made in China to release battery capacity for semi electric trucks and other nickel based electric vehicles that need higher density and longer endurance. < / P > < p > since then, musk has promised to use lithium iron phosphate batteries in more electric vehicles and energy storage systems. A Tesla in Houston, USA Lithium iron phosphate batteries will be used in Tesla energy project. < / P > < p > since this year, the price of cobalt has increased by about 70%, the price of nickel has increased by about 20%, and the price of aluminum has increased by about 50%. Tesla mainly uses these materials to make batteries, which is also the main reason for the increase in the cost of the company. (Chen) < / P > < p >
