Compared with the research results of lithium iron phosphate in the past 3 years, it is found that this technological innovation has obvious advantages, lithium iron phosphate batteries can discharge at −60℃, and low temperature discharge capacity is higher. Table 5. Comparison of low temperature discharge capacity of LiFePO 4 / C samples.
In this paper, according to the dynamic characteristics of charge and discharge of lithium-ion battery system, the structure of lithium iron phosphate is adjusted, and the nano-size has a significant impact on the low-temperature discharge performance.
This paper established a battery model of the lithium iron phosphate battery suitable for different temperatures, and then simulated the model combined with specific working conditions. The simulation results show that the model has a good tracking capability for the battery terminal voltage, and the average relative error is less than 1%.
Lithium iron phosphate battery works harder and lose the vast majority of energy and capacity at the temperature below −20 ℃, because electron transfer resistance (Rct) increases at low-temperature lithium-ion batteries, and lithium-ion batteries can hardly charge at −10℃. Serious performance attenuation limits its application in cold environments.
After 150 cycles of testing, its capacity retention rate is as high as 99.7 %, and it can still maintain 81.1 % of the room temperature capacity at low temperatures, and it is effective and universal. This new strategy improves the low-temperature performance and application range of lithium iron phosphate batteries.
However, the high and low temperature environments caused by regions and seasons have had a serious impact on the application of LIBs [2, 3]. Especially in the low-temperature environment, the discharge performance of the power battery will be greatly affected .
