“…First, pioneering efforts have been made to understand the mechanical behavior of LIBs that are subjected to physical abuses, e.g., radial compression [15,16], indentation [15,17], and bending [15] loads. The constitutive model for the jellyroll was first established by Greve and Fehrenbach [15] and Sahraei et al [18] through homogeneous isotropic material treatment.…”

“…The constitutive model for the jellyroll was first established by Greve and Fehrenbach [15] and Sahraei et al [18] through homogeneous isotropic material treatment. Since then, Lai et al [16] developed a representative volume element (RVE) model that considered each component of the jellyroll. Recently, an anisotropic model with coupled strain rate and state of charge (SOC) dependencies was proposed in Ref.…”

“…Constitutive models to predict the radial direction properties of jellyroll from the flow rule and the conception of volumetric strain were proposed by Greve and Fehrenbach [13] and Wierzbicki and Sahraei [15] respectively. Then the representative volume element model of the jellyroll was identified [16,17]. The anisotropic property of the structure as a result of geometry and material was not considered by these two models.…”

“…Ruling out the structural effects makes obtaining the material parameters of cathode and anode by tension and compression tests through staking up layers of the material rather straightforward [16,17]. The separator plays an important role in possible internal short-circuit and long-term electrochemical degradation [19][20][21][22][23].…”

h i g h l i g h t sAn anisotropic model to describe mechanical behaviors of LIB is established. SOC dependency is included in the mechanical model of the jellyroll. Dynamic effect is considered in the model for LIB. g r a p h i c a l a b s t r a c t a r t i c l e i n f o b s t r a c tHighly nonlinear structures and constituent materials and hazardous experiment situations have resulted in a pressing need for a numerical mechanical model for lithium-ion battery (LIB). However, such a model is still not well established. In this paper, an anisotropic homogeneous model describing the jellyroll and the battery shell is established and validated through compression, indentation, and bending tests at quasi-static loadings. In this model, state-of-charge (SOC) dependency of the LIB is further included through an analogy with the strain-rate effect. Moreover, with consideration of the inertia and strainrate effects, the anisotropic homogeneous model is extended into the dynamic regime and proven capable of predicting the dynamic response of the LIB using the drop-weight test. The established model may help to predict extreme cases with high SOCs and crashing speeds with an over 135% improved accuracy compared to traditional models. The established coupled strain rate and SOC dependencies of the numerical mechanical model for the LIB aims to provide a solid step toward unraveling and quantifying the complicated problems for research on LIB mechanical integrity.

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.
