What factors affect the low-temperature performance of 18650 battery 3.7v 6000mah packs
1. Positive level structure. Under ultra-low temperature conditions, the three-dimensional structure of the battery cathode material limits the external diffusion speed of lithium iron phosphate rechargeable batteries. At -20°C, the charge and discharge capacity of lithium iron phosphate rechargeable batteries can only reach % of the volume at room temperature, while nickel-cobalt-manganese ternary batteries can achieve %. At -20°C, the charge and discharge capacity of lithium manganate batteries reaches 83% of the volume at room temperature.
2. Organic solvents with high melting points. The high melting point organic solvent in the lithium iron phosphate rechargeable battery increases the viscosity in the ultra-low temperature environment. When the temperature is too low, condensation will occur, thereby reducing the transmission rate of the lithium-ion battery in the lithium battery electrolyte.
Third, it is the external diffusion rate of lithium-ion batteries. The low-temperature diffusion rate of lithium batteries in high-purity graphite negative stages decreases; the reduction in the diffusion rate of lithium batteries in high-purity graphite negative stages is the main reason for the degradation of the low-temperature characteristics of lithium batteries.
plastic film. The negative stage of the 18650 battery 3.7v 6000mah's SEI film thickens in a low-temperature environment, and the impedance of the SEI film increases, causing the conductivity of the lithium-ion battery in the SEI film to decrease. Ultimately, the lithium battery's battery performance in a low-temperature environment increases. Charging produces polarization and the battery charging efficiency is reduced.
Lithium iron phosphate rechargeable batteries have low energy density and deviations in ultra-low temperature characteristics. The battery cannot be charged at ultra-low temperatures. The nominal voltage is: , and the safety factor is very good. So far, there is no lithium iron battery with good ultra-low temperature characteristics. 18650 battery 3.7v 6000mah pack has a fatal flaw, that is, its ultra-low temperature characteristics are weak. Even if it is nanotechnology and carbon-coated, it cannot solve this problem. If this happens, the equipment will not be able to start working. In ultra-low temperature environments, lithium batteries have the characteristics of reduced charge and discharge voltage, reduced charge and discharge volume, fast volume attenuation coefficient, and poor multiple performance.
