What are the performance advantages of 18650 low-temperature battery

    1. How many stages of low-temperature polymer lithium batteries are as follows: In the range of -50℃ to 50℃, discharge with a rate of 0.2C can reach an effective discharge capacity of more than 75%; the effective life of the cycle is 150~200 times. When the temperature is between -40℃ and 60℃, the 0.2C ratio discharge has an effective discharge capacity of more than 85%, the 0.5C ratio discharge capacity is more than 75%, and the effective cycle life is more than 180 times; in the range of -30℃ to 65℃, the 0.2C ratio discharge has an effective discharge capacity of more than 90%, and the 2C ratio discharge can reach more than 75%, and the effective cycle life is more than 300 times. In the range of -20℃ to 75℃, 0.2C discharge rate, the effective discharge capacity is greater than 95%, which 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 will have deviations in the specific utilization situation and the utilization environment is complex. If the same is true, all the actual situation will be the main focus.  

　　2. Low cost and can be produced on a large scale. In terms of product components, in colloidal or solid electrolytes, compared with low-temperature polymer lithium batteries and low-temperature lithium iron phosphate batteries, when the voltage and capacity are similar, their components are lighter than low-temperature 18650 lithium batteries. From the perspective of production and manufacturing, these three low-temperature batteries are cost-effective, which is also one of the important factors that restrict their utilization.  

　　3. Advantages of adapting to equipment space requests. At present, low-temperature polymer lithium batteries are basically colloidal or solid-state lithium batteries, and their production process is a laminated process. Therefore, low-temperature polymer lithium batteries are relatively maneuverable and free in the design and manufacturing of battery capacity and appearance, and can basically be customized on demand. Especially for small ultra-thin batteries, it is more advantageous. At the beginning, this kind of battery that was used more frequently were portable electronic devices or smart clothing devices, especially cold adventure equipment, which were the preferred batteries at present.
