Compared with the battery force signal at the start of the experiment, the force increased 2.5 pounds due to battery thermal expansion caused by a 30°C temperature increase. After the short circuit, before venting, the peak force rose over 400 pounds. The sharp rise of force is the result of pressure that is built up due to formed gas. Pannala 17 using a
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.
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.
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.
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.
The primary reason is that the anode is in a mixed phase of LiC8 and LiC12 during the transition stage, resulting in minimal thickness variations. Thus, thermal expansion, coupled with the increase in cathode thickness, governs the expansion behavior during the transition stage of the discharge process.
