At present, lithium iron phosphate battery is one of the most used batteries. This kind of battery has high safety and long cell life. However, lithium iron phosphate has a fatal disadvantage, that is, the low temperature performance of lithium iron phosphate battery is better than other technical systems. The battery is slightly worse.Low temperature has an impact on the positive and negative electrodes, electrolyte and binder of lithium iron phosphate. The lithium iron phosphate positive electrode itself has relatively poor electronic conductivity, and it is prone to polarization in low temperature environments, thereby reducing battery capacity;Affected by low temperature, the lithium insertion rate of graphite is reduced, and metallic lithium is likely to precipitate on the surface of the negative electrode. If the lithium metal cannot be fully embedded in the graphite again if it is left for insufficient time after charging, it is very likely to be formed on the surface of the negative electrode. Lithium dendrites affect battery safety;At low temperatures, the viscosity of the electrolyte will increase, and the lithium ion migration resistance will also increase. In addition, in the production process of lithium iron phosphate, the adhesive is also a very critical factor, and low temperature will also affect the performance of the adhesive. Have a greater impact. So, we suggest lithium iron phosphate battery temperature range is -20℃ ~ +75℃.
