Can lithium iron phosphate batteries be used at minus 10 degrees?

As we all know, the lithium iron phosphate battery is a high -tech product with many chemical raw materials and complicated craftsmanship. It is not optimistic in the low -temperature environment (generally refers to the category of 0 degrees to 10 degrees). Not to mention at minus 10 degrees. This makes lithium iron phosphate batteries restricted in low temperature environments. The active activity of positive materials at low temperatures is reduced to decrease the amount of lithium ions that can bring to the discharge current, which is the root cause of the decline in capacity.

At low temperature, in the positive and negative electrode materials, the diffusion capacity of the ionic ions has deteriorated, the passivation membrane through the electrode and the electrolyte becomes difficult, the speed passed in the electrolyte is also reduced, and it will also occur during the transmission process. Many calories. After the lithium ions reach the negative electrode, the diffusion inside the negative electrode material becomes smooth. In the process of all, the movement of charged particles has become difficult. From the outside, the internal resistance of the battery is high. This makes lithium iron phosphate batteries almost unavailable.

If you look at it like this, it seems that the lithium iron phosphate battery cannot be used at minus 10 degrees. Really? In fact, this is not the case. Because there are many battery manufacturers who have studied at low temperature battery research, they have made great breakthroughs.

After a long -term R & D test summary of low -temperature iron phosphate batteries, it has proprietary formula and innovative technology. By using the proprietary electrolyte formula and other special functional raw materials, coupled with leading innovative technologies, the battery still ensures that the battery is still at a very low temperature. Performance of efficient discharge. The working temperature range is -40 ℃ to 50 ℃
