Computational modelling of structural batteries accounting for stress-assisted convection in the electrolyte

Structural batteries consist of carbon fibres embedded in a porous structural battery electrolyte (SBE), which is composed two continuous phases: solid polymer skeleton and liquid containing Li-salt. In this paper we elaborate on computational modelling framework to study the electro-chemo-mechanical properties such while accounting for combined action from migration as well stress-assisted diffusion convection electrolyte. Further, consider effects lithium insertion fibres, leading strains. The focus placed how convective contribution mass transport within SBE affects general properties. numerical results indicate that has only minor influence multifunctional performance when mechanical loading caused by constrained deformation constituents during electro-chemical cycling. However, case externally applied causes severe SBE, or large current pulses are applied, noticeable performance. addition, it shown porosity effective stiffness mobility permeability, significant
