Which power battery technology is strong?

　　Lithium battery companies took advantage of the trend and launched a new round of wrestling, and the battle for energy density began vigorously. So, the question is, which power battery technology is strong?

　　As we all know, science and technology are the primary productive forces. The development of science and technology and every major breakthrough will cause profound economic changes and tremendous progress in human society. In today's world, science and technology have become the most active factor in productivity.

　　In the current lithium battery industry, with the advanced and backward battery technology, whether the energy density can keep up with the pace of market development, it is not only the question of whether the subsidy can be obtained, but also the survival of the enterprise. The lithium battery big data survey found that among the hundreds of lithium battery companies in China, most of them invested 6% of their turnover in the research and development team, just to have more advanced battery technology.

　　Lithium battery companies took advantage of the trend and launched a new round of wrestling, and the battle for energy density started vigorously.

　　Then, the question is, which power battery technology is strong?

　　Guoxuan Hi-Tech

　　The Ministry of Science and Technology website reported on May 19 that, with the support of the key special project of the National Key R&D Program "New Energy Vehicles", the project led by Guoxuan Hi-Tech Power Energy Co., Ltd. "R&D and integration of high specific energy power lithium-ion batteries" "Application" has made phased progress, and the development of battery cell samples with energy densities of 281Wh/kg and 302Wh/kg has been completed.

　　Ningde era

　　On January 17, the "New Generation Lithium-ion Power Battery Industrialization Technology Development" project was launched in Ningde. This project is promoted by the Science and Technology Department of Fujian Province, and Ningde Times has jointly declared with the Institute of Physics and other units to develop a lithium-ion power battery with a high nickel ternary material as the positive electrode and a silicon-carbon composite as the negative electrode. The specific energy is greatly increased from the current 150-180Wh/kg to more than 300Wh/kg, and the cost will also be significantly reduced.

　　BYD

　　BYD’s battery technology is mainly lithium iron phosphate batteries, and as the main battery type for electric vehicles, BYD has the world’s top level in the research and development of lithium iron phosphate batteries.

　　At present, the single energy density of BYD lithium iron phosphate battery is 150Wh, and then BYD plans to continue to increase the energy density to 160Wh. In addition to lithium iron phosphate batteries, BYD is also simultaneously developing ternary lithium batteries. If the technology of ternary lithium batteries is combined with lithium iron phosphate batteries and some adjustments are made to the original practice of using graphite as a negative electrode material, then around 2020 , BYD plans to increase the single energy density of lithium iron phosphate batteries to 200Wh.

　　In addition, BYD's ternary battery has the conditions for mass production, and the current energy density has reached 200Wh/kg. The goal of BYD's ternary battery is to reach 240Wh/kg in 2018 and 300Wh/kg in 2020.

　　Tianjin Lishen

　　According to the website of the Ministry of Science and Technology on April 13th, the project "High specific energy density lithium ion power battery development and industrialization technology research" led by Tianjin Lishen Battery Co., Ltd. has completed the development of a power battery cell with an energy density of 260Wh/kg , Compared with the current power battery commonly used in electric vehicles, the energy density has increased by 30%.

　　Beijing Guoneng

　　National energy lithium iron phosphate battery energy density: batteries 160Wh/kg, PACK128Wh/kg, ternary power battery energy density: 240Wh/kg, reaching the world's advanced level.
