Thus, thermal expansion, coupled with the increase in cathode thickness, governs the expansion behavior during the transition stage of the discharge process. Furthermore, thermal expansion consistently increases battery thickness, aligning with the expansion behavior during charging but in contrast during discharge.
Thermal expansion is induced by thermal stress due to the temperature deviation during charge-discharge cycles. In this study, the thermal expansion behavior for a 38 Ah prismatic ternary battery is identified by presenting a three dimensional thermal-mechanical model.
Furthermore, thermal expansion consistently increases battery thickness, aligning with the expansion behavior during charging but in contrast during discharge. Consequently, the discharge process fails to reverse the thickness increase induced during charging.
The battery expansion behavior with different SOCs is investigated. Expansion behavior is proposed as a reliable characteristic for SOC estimation. The expansion mechanism of LIB with different SOCs is revealed. A SOC estimator utilizing the expansion feature is presented and verified.
In order to improve the energy storage and storage capacity of lithium batteries, Divakaran, A.M. proposed a new type of lithium battery material and designed a new type of lithium battery structure, which can effectively avoid the influence of temperature on battery parameters and improve the energy utilization rate of the battery .
Larger thermal stress and expansion are observed with increasing current and DOD, moreover, the battery expands more along the thickness direction and the tab portion where the temperature is higher. The maximum thermal average volume stain aroused by temperature difference during discharge at 1 C is 1.04 × 10 − 4.
