The impact of high temperature of base stations on batteries

Do high temperatures affect battery life?

High temperatures greatly affect battery life. For every 15 degrees Fahrenheit above 77°F, the lifespan of a lead-acid battery—including sealed, gel, AGM, and industrial batteries—can be reduced by half. Though batteries may average performance overall, excessive heat shortens their lifespan significantly.

How does high temperature affect lithium ion batteries?

High temperatures significantly affect lithium-ion batteries by reducing their lifespan and performance. Excessive heat can lead to increased chemical reactions within the battery that compromise its efficiency and safety. The specific effects of high temperature on lithium-ion batteries include:

What is the evolution mechanism of battery thermal safety under high-temperature conditions?

Under high temperature conditions, the cyclic aging and calendar aging tests are performed. After the tested battery decays to different aging levels, thermal runaway tests and multi-angle characterization tests are conducted to clarify the evolution mechanism of battery thermal safety under high-temperature conditions.

How does temperature affect battery performance?

According to a study by the National Renewable Energy Laboratory (NREL) in 2019, lithium-ion batteries can lose up to 20% of their capacity for every 10°C increase in temperature above 25°C. High temperature leads to performance degradation in batteries. This degradation often manifests as reduced charge retention and lower overall efficiency.
