In this work, various Lithium-ion (Li-ion) bat-tery models are evaluated according to their accuracy, com-plexity and physical interpretability. An initial classification into physical, empirical and abstract models is introduced.
In a structural battery, mechanical performances are critical due to the interaction between the stress/strain behavior and the electrochemical processes and it is highly dependent on the multifunctional design. In packing SBs, poor bonding between the energy storage component and the composite material is generally observed.
The structural design of the battery significantly influences its flexibility. Variations in the structural designs of the batteries result in them experiencing different forces during deformation, including the location of the force and the direction and magnitude of the stress.
Although flexible batteries have come a long way, most of them focus on the exploitation of advanced materials and the enumeration of potential structures. The prevailing approach to structure classification in the field is still based on the shape and mode of deformation of batter.
This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.
For structural batteries, the solid nature indicates that they can enhance not only the tensile and compressive properties of a battery, but also load-transfer between different layers and thus improve flexural properties.
The structural battery possesses an elastic modulus of 25 GPa and strength of 300 MPa and holds an energy density of 24 Wh kg −1. With its combined energy storage and structural functions, the structural battery provides massless energy storage.
The mechanical performance of a composite is influenced by the design and properties of its components. For structural batteries, the rigidity under bending is an important engineering criterion, which depends on whether the reinforcing components are placed inside or outside the battery.
