The current model simplifies or neglects a few other factors that should be addressed to provide a full description of chemo-mechanics in solid-state batteries in the future, for example, explicit description of interfacial and intergranular crack formation , concentration-dependent elastic modulus of NMC cathodes , plastic deformation in solid electrolytes , role of discrete dislocations and grain boundaries in Li diffusion and chemo-mechanics of NMC cathodes , and generation of the representative electrode particle microstructure from microscopy data .
