Is the lithium iron phosphate battery resistant to low temperature?48v 200ah home energy storage battery

　　Lithium iron phosphate has gradually been replaced by ternary materials in the market, but due to the low price of ternary materials, long life, and compatible with the low temperature characteristics of lithium iron phosphate batteries, it still has very good in the field of electric vehicles and electric bicycles. Good development prospects. However, in the process of use, there are many problems with lithium iron phosphate batteries: 1) Since the lithium iron phosphate material itself has the characteristics of easy corrosion and flammable, there will be large hidden dangers during use; 2) in lithium iron phosphate batteries during use; It contains a large amount of electrolyte solution (electrolyte is an organic system with water as the main solvent), which is very corrosive; 3) Due to the temperature of the oxidation and reduction reaction of lithium iron phosphate material, it is greatly affected by temperature, so at low temperature (≤-20 (≤ 2020 ° C) Vitality reaction is very easy to be analyzed at the time of charging; 4) Lithium iron phosphate batteries will also occur in low -temperature environments. In response to the above problems, this article will be improved from the following aspects. Lithium phosphate battery is a new type of battery with high working voltage, small volume, and light weight. It has the highest energy density in all lithium ion batteries, and has the characteristics of long life and high safety. Ion batteries are more stable and can work normally at -20 ° C, so they are widely used in automotive, electric bicycles and other fields. Lithium phosphate battery currently has three major series: lithium iron phosphate, lithium iron phosphate and ternary material. Among them, lithium iron phosphate has the highest energy density among the three materials, but due to its high cost and technical difficulty, it is restricted to use in high -end fields.

　　1. Improvement of battery materials

　　Currently in the market, lithium iron phosphate batteries mainly use the following three materials: (1) Lithium iron phosphate: Lithium iron phosphate currently used on the market is LFP. , But its low temperature performance is poor, the discharge capacity is only about 100 mAh/g under -20 ° C. Therefore, in response to this problem, the researchers set their sights on the advantages of LFP materials. Poor, the discharge capacity at -20 ° C is only about 100 mAh/g. However, the disadvantage of LFP materials is high costs and expensive prices. In order to overcome the above shortcomings, the researchers have improved LFP materials: the low temperature performance of the material is improved by doping other metal ions.

　　What are the mature power lithium battery technology?

　　What is the current battery technology? The technical trend of lithium ion batteries. Lithium -ion batteries will play an increasing role in our lives. However, with the development of these industries, people's demand for lithium ion batteries will continue to increase, and the requirements for lithium battery will continue to increase. The breakthrough of battery technology is very critical. Next, Xiaobian will introduce the current mature battery technology, and introduce the development trend of power lithium battery technology.

　　The state's strong support for its research and development will provide favorable conditions for its industrialization. However, if you want to realize industrialization, the first thing to solve is the technical problem faced by electric vehicles. In these technologies, batteries are still a big difficulty.
