lithium iron phosphate battery is between -50°C and 80°C, but in actual use, because chemical energy is not completely converted into electrical energy, and part of it is converted into heat energy, this makes the battery The internal temperature will increase with the increase of use time. Therefore, it is best for consumers to control the temperature below 50 degrees Celsius when using lithium iron phosphate batteries.
According to research, the working temperature range of lithium iron phosphate battery is between -50°C and 80°C, but in actual use, due to chemical energy and not completely converted into electrical energy, and part of the conversion into heat energy, which makes the internal temperature of the battery will increase with the use of time. Therefore, it is best for consumers to control the temperature below 50 degrees Celsius when using lithium iron phosphate batteries.
However, the biggest disadvantage of lithium iron phosphate batteries is poor low temperature resistance and poor conductivity. In low temperature environments, high conductivity electrolytes will freeze due to their low condensation point, resulting in the entire battery system. Capacity decreases, cycle stability performance deteriorates, and there will be disconnection during work.
In fact, regardless of whether the lithium iron phosphate battery is operating at high temperature or low temperature, both situations will cause greater loss to the battery. From a chemical point of view, although lithium iron phosphate batteries work at high temperatures is conducive to the conversion of electrode materials, but the discharge capacity is very large, resulting in a very short battery life of related power tools, frequent charging, and the battery capacity after a period of use decreased significantly.
In general, high temperature has a greater adverse effect on lithium iron phosphate batteries than low temperature, so when using the battery pack, try to control the working environment at a better temperature, so as to make lithium iron phosphate The battery is more durable.
