Temperature is considered to be an important indicator that affects the capacity of a lithium ion batteries. Therefore, it is of great significance to study the relationship between the capacity and temperature of lithium ion batteries with different anodes.
The optimal operating temperature of lithium ion battery is 20–50 °C within 1 s, as time increases, the direct current (DC) internal resistance of the battery increases and the slope becomes smaller. Between 1 s and 10 s, the DC internal resistance of the battery basically shows a linear relationship with time.
Jilte et al. observed that the localized temperature zone within lithium battery cells is influenced by the module’s position. In certain specific areas of the battery, temperature increases of up to 7 degrees Celsius were recorded, leading to the formation of a temperature gradient and compromising thermal uniformity within the battery cell.
The distribution of temperature at the surface of batteries is easy to acquire with common temperature measurement approaches, such as the use of thermocouples and thermal imaging systems . It is, however, challenging to use these approaches in monitoring the internal temperature of LIBs.
The self-production of heat during operation can elevate the temperature of LIBs from inside. The transfer of heat from interior to exterior of batteries is difficult due to the multilayered structures and low coefficients of thermal conductivity of battery components , , .
