Significant efforts are being made across academia and industry to better characterize lithium-ion battery cells as reliance on the technology for applications ranging from green energy storage to electric mobility increases. The measurement of short-term and long-term volume expansion in lithium-ion battery cells is relevant for several reasons. For instance, it provides information about the quality and homogeneity of battery cells during charge and discharge cycles, as well as aging over it’s lifetime. The expansion measurements are useful for the evaluation of new materials and the improvement of end-of-line quality tests during cell production. These measurements may also indicate the safety of battery cells by aiding in predicting state of charge and state of health over the lifetime of the cell. Expansion measurements can also assess inhomogeneities on the electrodes and defects such as gas accumulation and lithium plating. In this review, we first establish the known mechanisms through which short term and long term volume expansion in lithium-ion battery cells occurs. We then explore the current state-of-the-art for both contact and non-contact measurements of volume expansion. This review compiles existing literature to outline the various options available to researchers aiming to make ex situ volume expansion measurements by doing post mortem analyses on individual components and in operando measurements on entire battery cells. Finally, we discuss the different considerations when selecting an appropriate measurement technique. The selection of the optimal method for measuring battery cell expansion depends on the objective of the characterization, duration, required resolution, and repeatability of results. Costs and required space for the measurement equipment are also considered.

“…In the case of 1D imaging, high sampling rates are possible, as the only limitation in acquisition speed is the exposure time of the camera. Laser triangulation makes use of a relatively simple measurement principle, where only a source laser, a lens, and a line detector, as shown in Figure 12, are required [176,177] .…”

Expansion measurements can also assess inhomogeneities on the electrodes, in addition to defects such as gas accumulation and lithium plating. In this review, we first establish the mechanisms through which reversible and irreversible volume expansion occur. We then explore the current state-of-the-art for both contact and noncontact measurements of volume expansion. This review compiles the existing literature on four approaches to contact measurement and eight noncontact measurement approaches. Finally, we discuss the different considerations when selecting an appropriate measurement technique.

“…The above considerations paint a complex picture in which the large demand of high-quality three-dimensional models clashes with the limited affordability of a highly specialised offer. In fact, considering the field of industrial metrology, appropriate techniques and instruments for the rigorous description of small objects have been identified and consolidated over time [6][7][8]. However, it is not sure that these can be successfully applied to the cultural heritage area, both due to typological issues (it is not always a case of instrumentation that measures without contact and/or returns a texture datum) and different budget constraints.…”
