The ability of polymer lithium batteries to withstand high temperatures depends on a number of factors, including the design of the battery, the material, the manufacturing quality, and the specific operating conditions. In general, polymer lithium batteries may encounter some challenges in high temperature environments, but the specific temperature limits vary by battery type and manufacturer.
Here are some general guidelines:
Temperature range: Polymer lithium batteries generally perform better in a lower temperature range, generally between 0°C and 45°C. In this range, the performance and safety of the battery can usually be well guaranteed.
High temperature environment: If the polymer lithium battery is used in a high temperature environment, such as under conditions above 50°C, it may lead to reduced battery performance and reduced life. High temperatures can accelerate battery aging, potentially leading to reduced capacity, reduced cycle life, and increased safety risks.
Short-term high temperature: High temperature exposure for a short period of time can usually be tolerated by the battery, but sustained high temperature exposure can cause more serious effects on the battery. Therefore, be careful when storing or using batteries in high temperature environments.
Cooling: In some applications, such as electric vehicles, an active cooling system may be used to control the battery temperature to ensure that the battery will still work properly under high temperature conditions.
Manufacturing quality: The battery manufacturer's quality control also affects the battery's high-temperature performance. A high-quality manufacturing process can improve the battery's stability under extreme conditions.
In short, polymer lithium batteries are usually able to work at a certain degree of high temperature, but high temperatures can negatively affect their performance and life. Therefore, when designing and using batteries, factors in the high temperature environment should be considered, and appropriate measures should be taken to ensure the safety and performance stability of the battery. If you need to use the battery in extremely hot conditions, you may need to consider other types of batteries or take special cooling measures.
