Low/high Temperature Test Chamber for high-low temperature resistance test of lithium manganate power battery

Lithium manganese oxide power battery is a new type of high-performance power battery, which has the advantages of high energy density, high safety and long life, and has been widely used in electric vehicles, hybrid vehicles and energy storage and other fields. Since the electrochemical reaction of lithium manganate power battery is carried out under high temperature conditions, high-low temperature resistance tests need to be carried out during production and use, so as to ensure its stable performance and safety under different temperatures and environments sex. In a high-temperature environment, lithium manganese oxide power batteries may have problems such as overheating, leakage, and capacity attenuation, while in a low-temperature environment, the electrochemical reaction speed of the battery may slow down, resulting in problems such as a decrease in battery capacity and a shortened lifespan. Therefore, through high-low temperature resistance tests, the performance and safety of lithium manganese oxide power batteries at different temperatures and environments can be evaluated, and its design and manufacturing process can be optimized to improve the reliability and stability of the battery and meet the requirements of different application fields. battery performance requirements.

The high-low Temperature Test Chamber can be used for high-low temperature environment tests of lithium manganate power batteries to verify their performance and safety under extreme temperature conditions.
