One of the immediate effects of temperature on lithium battery performance is its influence on energy efficiency. At elevated temperatures, lithium-ion batteries tend to exhibit higher discharge rates, resulting in increased power output. While this might seem advantageous, it comes at a cost – accelerated degradation of the battery components.
The self-production of heat during operation can elevate the temperature of lithium-ion batteries (LIBs) from inside. The transfer of heat from the interior to the exterior of batteries is difficult due to the multilayered structures and low coefficients of thermal conductivity of battery components.
Stage III starts with the melting of polyethylene (PE) separators at 130–140 °C, which leads to the micro internal shorting (stage IV) and the continuing rise of temperature. This reaction is an exothermic reaction, which generates heat and promotes the elevation of temperature inside the batteries.
In cold climates, lithium batteries can experience reduced capacity and power output due to a phenomenon called “cold cycling.” The electrolyte in the battery can become more viscous at low temperatures, impeding ion flow and limiting the battery’s ability to deliver energy.
While it's easy to measure the surface temperature of batteries using thermocouples and thermal imaging systems, it is challenging to monitor the internal temperature of lithium-ion batteries (LIBs) using these approaches.
