“…Simulations quit when the concentration of lithium Li ⊕ inside the cathode reaches the saturation limit c sat Li ⊕ , after 1085s and 50s respectively. Cathodic saturation is indeed the limit factor for the battery operation (see also [52] for an extensive discussion on limiting factors in electrochemical cells, induced by materials and architectures). At the initial time the electric potential discontinuity at the interfaces make Butler-Volmer currents vanishing.…”

In recent times, there has been significant enthusiasm for the development of all solid state batteries. This interest stems from a dual focus on safety—addressing concerns related to toxic and flammable organic liquid electrolytes—and the pursuit of high energy density. \cite{SCHNELL2018160,Zheng2018}. While liquid electrolyte batteries constitute for now the vast majority of commercial cells, solid electrolyte batteries show great promise. In parallel with experimental research, computational models \cite{GrazioliEtAlCM2016} clarify the several fundamental physics \cite{LiMonroeARCBM2020} that take place throughout battery operations. We review some classical models, emphasizing the conceptual advancements documented in the most recent works.

“…the maximal concentration of hostsites 𝑐 0 , the fraction of Li that resides in equilibrium in the mobile state, 𝛿, and the equilibrium constant of reaction (1), 𝐾 ion eq . Assuming that 𝑐 0 can be estimated with high accuracy on theoretical grounds, the interest is to study the effect of 𝛿 and 𝐾 ion eq on the steady state solutions ( 55) and (56).…”

This note is about a novel, thermodynamically consistent formulation for small strains continuum electro-chemo-mechanics applied to all solid state batteries, which are claimed to be the next-generation battery system in view of their safety accompanied by high energy densities. The response of a cell, made of a lithium metal foil, a solid electrolyte, and a porous LiCoO2 cathode, has been investigated in terms of quantities of interest such as the electric potential, the lithium concentrations profiles, displacements, and stresses. The plating and stripping of the lithium has been considered together with the volumetric evolution of the porous cathode. Together they contribute to the outbreak of mechanical stresses, which may influence the life cycle of a battery.
