Lithium Iron Phosphate Battery Revitalize with Vitality


The technology of power batteries for new energy vehicles has undergone a huge reversal at the beginning of 2020, and lithium iron phosphate batteries have hit with huge market prospects once again.


BYD announced in January that it will release a "Blade Battery" with basis of lithium iron phosphate technology. Then an exclusive report from Reuters revealed in February that Tesla is discussing for a cooperation on cobalt-free batteries with CATL. The discussion has stepped on the final stage, and both parties have basically reached a purchase intention. Reuters pointed the cobalt-free battery to the lithium iron phosphate battery intentionally or unintentionally in this report.

LFP Battery from Great Power


Great Power has installed nearly 100,000 vehicles for new energy vehicle companies since 2014, which includes nearly 70,000 vehicles for lithium iron phosphates, and the market has been fully verified. As a dark horse player among power battery suppliers for new energy vehicles in 2019, Great Power has increased its installed capacity year after year, ranking all the way up, and won the 9th place around China in the total installed capacity of power batteries for new energy vehicles in 2019. The number of installed lithium iron phosphate ranks the 5th in China in 2019. (The data is from: Starting Point Lithium Battery Big Data)


Great Power has continued to invest in R & D and technological iterations of lithium iron phosphate batteries in the past few years, compared with the vigorous advancement of ternary batteries in the field of passenger vehicles. Great Power adherers and advocates the development of lithium iron phosphate batteries. Great Power has carried out deep research on the leading new technologies in the industry, learned from the best, developed a new technical solution combining lithium iron phosphate batteries and Pack with more unique features at the same time of independent innovation, in which the volume energy density is further improved, and the endurance mileage is expected to be more than 450kms, which reached the leading level in the industry. We are carrying on joint development and technical demonstration with well-known entire automobile manufacturers in China at present, let's wait and see what happens!


Advantages of the LFP Batteries from Great Power


Great Power has been cultivating in the field of lithium iron phosphate batteries for many years, and has formed a technological concept of leading by innovation and customer first, which has broken through and mastered a large number of core technologies with independent intellectual property rights. The internal resistance and temperature rise of the cell is reduced through homogeneously coated positive electrode, optimizing of particle size and crystal structure, and the construction of a three-dimensional high-speed conductive network. In the aspect of negative electrode, the development and application of new additives greatly shortens the migration path of lithium ions. In terms of workmanship, the unique cell structure design reduces the internal resistance and increases the energy density of the cell significantly. Persistent technical innovation has enabled the energy density of lithium iron phosphate battery cells from Great Power exceed 200Wh / kg, and the cycle exceeds 7000 times.


In the application of square products, Great Power released a series of ace products with excellent cost performance, such as 34135214-113Ah42173166-135Ah54173192-206Ah, etc.


The advantages of these products are focusing on the following aspects: The energy density is significantly raised: the energy density of the single cell of the square aluminum case can reach 175 Wh / kg through the improvement of pole piece manufacturing technology and the optimization of the winding assembly process. Break through the bottleneck of cryogenic technology: it solves the problem of performance attenuation under low temperature by using a new type of additive system, while ensuring high energy density. It can still maintain good charge and discharge performance under -20 ℃ Excellent safety performance: it can pass various strict safety performance tests through the optimized design of the chemical system and structural parts, such as overcharge, needling, squeeze, short circuit, thermal abuse, etc. Significant advantage on price: the cost reduction of iron-lithium batteries from Great Power far exceeds the industry average through strict screening and evaluation of raw materials and strict control of process yield. In addition, the lithium iron phosphate battery also has core advantages in itself such as long cycle and environmental friendliness.


Customers’ Acceptance


Great Power has successfully loaded lithium iron phosphate power batteries for Dongfeng Automobile, SAIC-GM-Wuling, Jiangnan Automobile, Joylong Automobile, Zhuhai Guangtong Automobile, Hebei Chang’an Automobile, Liuzhou Wuling Automobile, Chery Commercial Vehicle (Anhui) and many other well-known new energy vehicle companies, including passenger vehicles, buses, logistics vehicles, special vehicles and other application fields. These vehicles are currently running well, and there is excellent reputation among customers.


The Road Ahead


In the future, Great Power will draw on the essence of CATL CTP technology and BYD blade battery technology in terms of power battery technology research and development, deepen the development in the field, raise R & D and innovation, and create star products that belong to Great Power.
