They proposed a method to decouple battery heat generation and air pressure change rates, accurately identifying harmful reactions and enabling early warnings for battery safety. Compared with FBGs or FPIs, distributed optical fiber sensors are suitable for measuring temperature and strain throughout an extended volume.
CT is a stereoscopic imaging technology that enables three-dimensional detection of the internal structure of batteries without any blind spots, allowing for comprehensive assessment of various components such as pole plates, pole ears, coated electrode materials, and battery shells.
This capability is of critical importance for the identification of defects that could lead to battery failure or safety issues, and guide the optimization of LIBs with better safety and performance. This perspective review briefly summarize the comprehensive application of industrial CT in LIBs including battery materials, cells and modules.
In this framework, non-destructive inspection methods play a fundamental role in assessing the condition of lithium-ion batteries, allowing for their thorough examination without causing any damage.
Choosing the appropriate method depends on the application and the type of information required from the battery, such as state of charge (SOC), internal or external defects, state of health (SOH), accessibility, heat generation, and real-time measurements.
For instance, in situ transmission electron microscopy (TEM) has been used to uncover dynamic variations in Li-ion batteries. [ 62, 63] However, such in situ testing is limited to customized batteries, and not applicable to in situ monitoring energy-storage devices in real-world applications.
This technique can reveal the presence of cracks, voids, and other defects that may affect the performance and safety of the battery. XCT can also be used to study the distribution of active materials in the battery and to monitor changes in its internal structure during charge and discharge cycles.
