The temperature monitoring of lithium batteries necessitates heightened criteria. Ultrasonic thermometry, based on its noncontact measurement characteristics, is an ideal method for monitoring the internal temperature of lithium batteries.
To ensure experimental safety during measurement, the battery is heated to around 80 °C and then allowed to cool in a natural environment. During the cooling process, ultrasonic and temperature data are sampled and recorded every 10 s, and the measurement automatically stops when the battery temperature drops below 30 °C. Figure 4.
Temperature rise in Lithium-ion batteries (LIBs) due to solid electrolyte interfaces breakdown, uncontrollable exothermic reactions in electrodes and Joule heating can result in the catastrophic failures such as thermal runaway, which is calling for reliable real-time electrode temperature monitoring.
Based on this finding, in the time delay–temperature measurements of stacked lithium-ion batteries, controlling the pressure applied by the probe to the battery surface and ensuring equal force significantly improve the consistency of the multiple measurements, which is superior to the earlier experiments with wound lithium-ion batteries. 8.
Therefore, in order to cope with the temperature sensitivity of Li-ion battery and maintain Li-ion battery safe operation, it is of great necessary to adopt an appropriate battery thermal management system (BTMS).
