Which low temperature lithium battery is better

Which low temperature lithium battery is better? 1. Soft-pack low-temperature polymer lithium battery Soft-pack low-temperature polymer lithium battery should have the best low-temperature performance, especially in smart wearable devices, it has better advantages. The shape and size of the soft-pack low-temperature polymer lithium battery can be manufactured according to the space reserved for the equipment, which is sufficient to make the equipment meet the requirements of more ideal practical use. However, in terms of processing and manufacturing costs, the soft-pack low-temperature polymer lithium battery is the most expensive, which is one of the important factors that restrict its use. 2. Low temperature 18650 lithium battery The low temperature 18650 lithium battery is a fixed size cylindrical steel shell lithium battery. Since the electrolyte used in the cylindrical steel shell 18650 battery is liquid, the discharge performance in a lower temperature environment is greatly changed. . In terms of use, due to the fixed performance and size of the battery, the use range is relatively small, but its processing and manufacturing costs are relatively low, lower than low-temperature polymer lithium batteries and low-temperature lithium iron phosphate batteries. 3. Low-temperature lithium iron phosphate battery Low-temperature lithium iron phosphate battery has two outsourcing forms, one is a steel shell, which is currently mostly used in the field of new energy batteries; the other is a soft package iron phosphate with aluminum-plastic film as the outer packaging Lithium batteries. The performance of this type of battery is basically the same as that of polymer lithium batteries. Knowledge is better than 18650 lithium batteries in low temperature performance, and worse than soft-pack polymer lithium batteries. Because lithium iron phosphate batteries are related to the other two in terms of technological maturity It is worse, and at the same time, the equipment requirements are relatively high in terms of processing and manufacturing technology.
