Graphite batteries are a commonly used battery type, which may undergo physical and chemical changes under different environmental conditions, thereby affecting its performance and lifetime. In practical applications, graphite batteries may need to withstand extreme environments such as high temperature and low temperature. For example, in the fields of electric vehicles and drones, they need to be used in extreme temperature environments. Therefore, in order to ensure that graphite batteries can maintain their performance and life in different environments, it is necessary to conduct high-low temperature resistance tests to evaluate their electrochemical performance and capacity retention at different temperatures, so as to ensure their reliability in practical applications. reliability and stability.
The high-low Temperature Test Chamber can be used for high-low temperature resistance tests of graphite batteries to evaluate the performance and reliability of batteries in extreme temperature environments.
experiment method
Choose a graphite battery that meets the specifications to make sure it has enough charge and is working properly.
Place the graphite battery in a high-low Temperature Test Chamber and make sure that its surface is not damaged or deformed.
According to the test requirements, set the temperature range and lifting speed of the high-low Temperature Test Chamber, for example: -40°C~+80°C, the lifting speed is 5°C/min.
Start the high-low Temperature Test Chamber, and start the high-low temperature cycle test. The test time can be set according to the requirements, for example: keep at each temperature point for 2 hours, and cycle 10 times.
During the test, observe the working state and appearance changes of the graphite battery, and record the data. For example: voltage, current, temperature, capacity, etc.
Evaluate the performance and reliability of graphite batteries by analyzing test data. For example: observe the voltage change of a battery at different temperatures to evaluate its reliability in extreme temperature environments.
After the test is completed, close the high-low Temperature Test Chamber, and take out the test sample. Follow-up battery performance evaluation and analysis, if required.
