What kind of high temperature battery? What is the temperature range of the high temperature battery

High temperature resistant ternary lithium-ion batteries Generally speaking, lithium-ion batteries are not sensitive to the temperature in the range of 0-40°C. However, once the temperature exceeds this range, the life and capacity will be compromised. Therefore, the operating temperature for the full performance of lithium-ion batteries is usually 0-40°C. When the ternary lithium-ion battery is operated at a temperature above 50°C and below 60°C, the attenuation of the battery will accelerate and the life span will be reduced to a certain extent. The temperature of lithium-ion batteries required by some special environments is different, and some can even run normally in an environment of hundreds of degrees Celsius. The ternary lithium-ion battery adapts to a wide range of operating temperatures, and its electric heating peak can reach 350°C-500°C . The chemical characteristics of lithium-ion metal after encountering heat are very active. At the same time, the heat-resistant temperature of the battery is basically around 200 degrees, and when the temperature reaches the heat-resistant temperature, the chemical reaction of the ternary lithium-ion material will be more Violent, the electrolyte burns rapidly under high temperature applications. High temperature resistant polymer lithium ion battery Generally speaking, the operating temperature of polymer lithium ion battery is between -20℃ and 70℃. Too high or too low temperature will affect the capacity of the battery, that is, the discharge capacity will be reduced. At the same time, the chemical structure of the internal materials of the battery will be destroyed and changed, which will seriously affect the battery life. The high-temperature-resistant lithium-ion battery can withstand a high temperature of up to 800 degrees. Generally, lithium-ion batteries have 200 degrees, 500 degrees, and 800 degrees in high temperature testing, but under normal circumstances, we will not be exposed to such high temperatures in our daily life, but we can see charging from time to time. Or the battery is damaged when the appliance is overused. In particular, more and more smart devices are equipped with curved batteries. There are up to 50 safety monitoring procedures for safety testing alone. Among them, high-temperature items exceed 50 degrees when the curved battery is formed. In daily life At this temperature, the battery is unlikely to be touched. High-temperature lithium-ion batteries can generally be charged and discharged 300-500 times. It is better to discharge the lithium-ion battery partially rather than completely, and try to prevent frequent complete discharge. Once the battery is off the processing line, the clock starts to move. Regardless of whether you use it or not, the service life of lithium-ion batteries is only two to three years. High temperature resistant lithium iron phosphate battery High temperature resistant lithium iron phosphate battery packs can generally be divided into five levels for use in environments of 100°C, 125°C, 150°C, 175°C, and 200°C and above. Currently, the electrochemical systems used in a large number of primary high-temperature batteries are lithium ion/thionyl chloride and lithium ion/sulfuryl chloride (chlorine). This is because in all current electrochemical systems, these two systems have the highest specific energy, the widest operating temperature range, the longest storage time, and the highest working voltage. The temperature range of the high temperature resistant battery In all electrochemical systems, the high temperature resistant battery has the longest storage time, the highest working voltage, and the surrounding temperature requirements are completely different. 1. Li-ion batteries used at 150°C and 175°C should be specially designed; 2. Li-ion batteries used at 100°C or lower should not be specially designed. Generally, lithium-ion batteries on the market can be used after appropriate improvements; 3 , Lithium ion batteries used at 125°C or lower can be processed into qualified products as long as they are properly adjusted and controlled on the basis of conventional battery processing technology; 4. Lithium ion batteries used at 180°C and 200°C or higher can be processed because of lithium ion The melting point of 180.5 ℃ is no longer suitable for negative electrode, this kind of lithium ion battery must use lithium ion alloy as the negative electrode.
