What are the advantages of low temperature battery performance
1、 How many stages of low temperature polymer lithium battery
The categories are as follows:
In the range of - 50 ℃ to 50 ℃, more than 75% of the effective discharge capacity can be achieved with 0.2C rate discharge; The cycle effective life is 150 ~ 200 times.
When the temperature is between - 40 ℃ and 60 ℃, discharge at 0.2C rate, the effective discharge capacity is more than 85%, the 0.5c discharge capacity is more than 75%, and the effective cycle life is more than 180 times; In the range of - 30 ℃ to 65 ℃, the effective discharge capacity of 0.2C rate discharge is more than 90%, the 2C rate discharge can reach more than 75%, and the effective cycle life is more than 300 times.
In the range of - 20 ℃ to 75 ℃, the effective discharge capacity of 0.2C rate discharge 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 be biased due to the specific utilization situation, because the utilization environment is complex, but in the same way, all are based on the actual situation.
2、 Low cost, large-scale production
In terms of product weight, in colloidal or solid electrolyte, compared with low-temperature lithium iron phosphate battery, the weight of low-temperature polymer lithium battery is lighter than that of low-temperature 18650 lithium battery under the same voltage and capacity. From the original point of view of production and manufacturing, these three low-temperature batteries are cost-effective, which is also one of the important factors restricting their utilization.
3、 Advantages of adapting to device space requests
At present, low-temperature polymer lithium batteries are basically colloidal or solid-state lithium batteries, and their production process is lamination process. Therefore, low-temperature polymer lithium batteries can be more mobile and free in the design and manufacture of battery capacity and shape, and can basically be customized on demand. Especially for small ultra-thin batteries, it has the upper hand. At the beginning, portable electronic devices or smart clothing devices were used more, especially cold exploration devices. At present, batteries are the preferred choice.
