What are the performance advantages of 18650 low-temperature batteries.

1、 The temperature range for low-temperature polymer lithium batteries is as follows: within the range of -50 ℃ to 50 ℃, discharging at a rate of 0.2C can achieve an effective discharge capacity of over 75%; The effective lifespan of reincarnation is 150-200 times. When the temperature is between -40 ℃ and 60 ℃, the effective discharge capacity is over 85% when discharged at a rate of 0.2C, over 75% when discharged at a rate of 0.5C, and the effective cycle life is over 180 times; Within the range of -30 ℃ to 65 ℃, the effective discharge capacity is over 90% when discharged at a 0.2C rate, and over 75% when discharged at a 2C rate. The effective cycle life is greater than 300 times. In the range of -20 ℃ to 75 ℃, with a discharge rate of 0.2C, the effective discharge capacity is greater than 95%, and can reach 5C discharge. The effective discharge capacity is greater than 65%, and the effective cycle life is greater than 300 times. The above basic data may have deviations due to specific utilization situations, as the utilization environment is complex. Therefore, all should be based on actual situations.   

2、 Low cost, capable of large-scale production. In terms of product weight, compared to low-temperature lithium iron phosphate batteries in colloidal or solid electrolytes, low-temperature polymer lithium batteries have lighter weight than low-temperature 18650 lithium batteries when the voltage and capacity are the same. From the perspective of production and manufacturing, these three types of low-temperature batteries are all expensive, which is also one of the important factors restricting their utilization.
