“…Pouching of cells has been shown to dramatically improve most mechanical properties of Li-ion cells, compared to those without a pouch [17]. To-date most studies on the mechanical performance of Li-ion batteries have focused on the relationship between mechanical loading and the onset of an internal short circuit [17–22]. Li-ion pouch batteries have been subjected to a range of mechanical tests including out-of-plane compression, in-plane compression, punch indentation, impact and three-point bending tests [17–22].…”

This paper investigates the mechanical properties of lithium-ion polymer (LiPo) batteries and their subsequent use in the design of multifunctional sandwich panels for automotive applications. Shear properties, flexural properties and compression properties of prismatic pouch LiPo batteries are determined experimentally through a hole-punch test, a three-point bending test and an in-plane compression test, respectively. This study is the first to characterize the shear properties of a lithium-ion battery, which are critical in sandwich panel design. The mechanical properties of the batteries obtained are then applied to existing analytical models of multifunctional sandwich panels consisting of carbon fibre composite facesheets and LiPo battery cores, which are currently being considered for use in automotive panel design. A material selection procedure for a stiffness-limited automotive car door panel subjected to bending shows that a trade-off between mechanical performance and cost can be achieved by using a composite sandwich panel with thin LiPo battery cores or by embedding larger LiPo batteries in lower-density polymer foam cores. The practicality and implementation aspects of using sandwich composites with LiPo battery cores in automotive design are also discussed.

“…Most studies at the single battery level have focused on the relationship between the type and magnitude of mechanical loads and the onset of internal short circuiting due to damage. [ 27–35 ] LiPo batteries are anisotropic in their mechanical properties, which have been characterized in multiple directions. The properties of LiPo batteries have been measured for different mechanical conditions, including out‐of‐plane compression, [ 27 ] in‐plane compression, [ 27,36–38 ] punch indentation, [ 27,30,33–35,37 ] impact, [ 31 ] nail penetration, [ 39,40 ] three‐point bending, [ 27,28,37 ] and tension.…”

Integration of lithium‐ion batteries into fiber‐polymer composite structures so as to simultaneously carry mechanical loads and store electrical energy offer great potential to reduce the overall system weight. Herein, recent progresses in integration methods for achieving high mechanical efficiencies of embedding commercial lithium‐ion batteries inside composite materials are reviewed. The manufacturing techniques used to fabricate energy storage structural composites are discussed together with a comparison of their mechanical properties, energy storage capacity, and electrical performance. The mechanical performance of energy storage composites containing lithium‐ion batteries depends on many factors, including manufacturing method, materials used, structural design, and bonding between the structure and the integrated batteries. Energy storage composites with integrated lithium‐ion pouch batteries generally achieve a superior balance between mechanical performance and energy density compared to other commercial battery systems. Potential applications are presented for energy storage composites containing integrated lithium‐ion batteries including automotive, aircraft, spacecraft, marine and sports equipment. Opportunities and challenges in fabrication methods, mechanical characterizations, trade‐offs in engineering design, safety, and battery subcomponents are also discussed.

In this research, the aim relates to the material characterization of high-energy lithium-ion pouch cells. The development of appropriate model cell behavior is intended to simulate two scenarios: the first is mechanical deformation during a crash and the second is an internal short circuit in lithium-ion cells during the actual effect scenarios. The punch test has been used as a benchmark to analyze the effects of different state of charge conditions on high-energy lithium-ion battery cells. This article explores the impact of three separate factors on the outcomes of mechanical punch indentation experiments. The first parameter analyzed was the degree of prediction brought about by experiments on high-energy cells with two different states of charge (greater and lesser), with four different sizes of indentation punch, from the cell’s reaction during the indentation effects on electrolyte. Second, the results of the loading position, middle versus side, are measured at quasi-static speeds. The third parameter was the effect on an electrolyte with a different state of charge. The repeatability of the experiments on punch loading was the last test function analyzed. The test results of a greater than 10% state of charge and less than 10% state of charge were compared to further refine and validate this modeling method. The different loading scenarios analyzed in this study also showed great predictability in the load-displacement reaction and the onset short circuit. A theoretical model of the cell was modified for use in comprehensive mechanical deformation. The overall conclusion found that the loading initiating the cell’s electrical short circuit is not instantaneously instigated and it is subsequently used to process the development of a precise and practical computational model that will reduce the chances of the internal short course during the crash.
