Mechanical characterisation of a structural battery electrolyte

Year: 2024

Type: article

Abstract: Structural battery composites require a structural electrolyte to work. The structural battery electrolyte has a bicontinuous microstructure which enables its dual roles: mechanical load transfer and ion transport between the electrodes. To date, no complete characterisation of the mechanical properties of the structural battery electrolyte has been performed. This is mainly due to the complexity of sample preparation. Here, a procedure to manufacture specimens for tensile and compression tests is established. The executed test campaign provides measures of Young’s modulus and Poisson’s ratio, as well as tensile and compressive strength and strain to failure. In addition, cure shrinkage is investigated and found insignificant. These results are crucial for the further development of structural battery composites as they allow for accurate prediction of their internal stress states.
