Wide temperature lithium battery is a kind of lithium battery with special performance, which can work normally in a wide temperature range. The following is a detailed introduction about wide temperature lithium battery:
I. Performance characteristics:
1. Wide temperature range adaptability: Generally speaking, wide temperature lithium batteries can maintain good performance in low-temperature environments, such as in minus 20 ℃ or even lower temperatures work normally; at the same time, in high-temperature environments, but also in the 60 ℃ and above the temperature under the stable operation of some of the advanced lithium batteries can be even in minus 70 ℃ to minus 80 ℃ of the temperature range of the extreme normal use.
2. High energy density: means that in the same volume or weight, wide temperature lithium batteries can store more energy, to provide a longer life for the device, which is very important for some of the higher battery life requirements of the device, such as drones, electric vehicles and so on.
3. High discharge rate: it can output current quickly to meet the demand of the equipment in high power operation, such as in the power tools, electric car acceleration and other scenarios can quickly provide enough power.
4. Good cycle life: after many charging and discharging cycles, it can still maintain high capacity and performance, usually the cycle life can reach more than 2000 times, which reduces the frequency of battery replacement and lowers the cost of use.
5. High reliability: with good stability and safety, it can ensure the normal operation of the battery in various complex working environments and reduce the risk of equipment damage or safety accidents caused by battery failure.
II. How it works:
The working principle of wide temperature lithium batteries is similar to that of ordinary lithium batteries, in that the charging and discharging process is realized through the embedding and detaching of lithium ions between the positive and negative electrodes. During charging, lithium ions are detached from the positive electrode material and transferred to the negative electrode through the electrolyte to be embedded in the negative electrode material; during discharging, lithium ions are detached from the negative electrode and return to the positive electrode while generating current. In order to achieve a wide temperature range of operating performance, wide-temperature lithium batteries have been optimized and improved in terms of material selection, electrolyte formulation and battery structure design. For example, the use of new anode materials can improve the diffusion performance of lithium ions at low temperatures and improve the low-temperature performance of the battery; the optimization of the composition and formulation of the electrolyte can improve the stability and safety of the battery at high temperatures.
III. Areas of application:
1. Aerospace field: in space, the temperature changes are very large, wide temperature lithium batteries can adapt to this extreme temperature environment, providing reliable power support for satellites, space stations and other spacecraft.
2. Polar scientific research field: the temperature in the polar region is extremely low, the performance of ordinary batteries will be seriously affected, and wide temperature lithium batteries can provide stable power supply for scientific research equipment, communication equipment and other equipment in this harsh environment.
3. New energy vehicle field: in winter, the temperature in some areas is low, the range of ordinary lithium batteries will be greatly reduced, and wide temperature lithium batteries can maintain a better performance at low temperatures, to improve the range and reliability of electric vehicles, is expected to solve the new energy vehicle winter range shrinkage and low-temperature start-up difficulties and other problems.
4. Energy storage field: used in solar energy, wind energy and other renewable energy storage system, can work stably in different seasons and climatic conditions, improve the efficiency of energy utilization.
5. Industrial field: in some industrial equipment, such as robots, automated production lines, etc., the battery needs to be able to work in a wide range of temperatures, wide-temperature lithium batteries can meet the needs of these devices.
