Performance characteristics of high temperature and low temperature lithium batteries
The following are the performance characteristics of high temperature lithium batteries and low temperature lithium batteries:
First, high temperature lithium battery performance characteristics
1. Good high temperature resistance: it can work stably in a higher temperature environment, such as some high temperature lithium batteries can be used normally at temperatures above 100 ° C, 125 ° C, 150 ° C, 175 ° C or even 200 ° C, far beyond the operating temperature range of ordinary lithium batteries.
2. Large storage capacity: it can store more electricity, and the power supply capacity is larger than that of ordinary batteries, which can reach several times that of ordinary batteries, so as to provide more lasting power support for the equipment.
3. Long life: in high temperature environment, its cyclic charge and discharge life performance is excellent, after multiple charging and discharging, it can still maintain good performance, reducing the trouble and cost of frequent battery replacement.
4. High charge and discharge efficiency: under high temperature conditions, the charge and discharge cycle stability is better than that of traditional lithium batteries, which can reach saturation power in a short charging time, and the constant voltage can be maintained during the discharge process to ensure the stability of downstream equipment in the power supply process.
5. Good environmental performance: no toxic and harmful substances will be produced during processing and use, and no harm will be caused to the environment after scrapping, in line with the concept of green environmental protection.
Second, low temperature lithium battery performance characteristics
1. Low temperature resistance: Can work normally and discharge in very low temperature environment, such as civil low temperature lithium battery at -20 ℃ 0.2C discharge accounted for more than 90% of the rated capacity, special low temperature lithium battery at -40 ℃ 0.2C discharge accounted for more than 80% of the rated capacity, extreme environment low temperature lithium battery at -50 ℃ can also have a certain discharge capacity, Meet the power needs of cold areas or special low-temperature environment equipment.
2. High energy density: More electrical energy can be stored in a relatively small volume, making the device smaller and lighter in the case of obtaining the same amount of electricity, suitable for equipment with strict requirements on volume and weight.
3. Good charge and discharge efficiency: Although in a low temperature environment, its charge and discharge efficiency can still be maintained at a high level, which can be quickly charged and discharged in a low temperature environment to ensure the continuous stable power supply of the equipment.
4. Long cycle life: it can withstand frequent charge and discharge in low temperature environment. After multiple charge and discharge cycles, the performance attenuation of the battery is small, and it can provide stable power for the equipment for a long time.
5. High safety: It has good safety performance, such as through UL/CE/UN and other relevant certifications, and is not prone to fire, explosion and other safety accidents when used in low temperature environment, providing reliable safety protection for equipment and personnel.
6. Flexible size: According to customer needs, customized design can be made in size and shape, which can better meet the installation and use requirements of different equipment.
