Anaysis of the validity of P2D models for solid-state batteries in a large parameter range
Stephan Sinzig, Christoph P. Schmidt, Wolfgang A. Wall
Simulation models are nowadays indispensable to efficiently assess or optimize novel battery cell concepts during the development process. Electro-chemo-mechano models are widely u…

A conservative and efficient model for grain boundaries of solid electrolytes in a continuum model for solid-state batteries
Stephan Sinzig, Christoph P. Schmidt, Wolfgang A. Wall
A formulation is presented to efficiently model ionic conduction inside, i.e. across and along, grain boundaries. Efficiency and accuracy is achieved by reducing it to a two-dimens…

An efficient approach to include transport effects in thin coating layers in electrochemo-mechanical models for all-solid-state batteries
Stephan Sinzig, Christoph P. Schmidt, Wolfgang A. Wall
A novel approach is presented to efficiently include transport effects in thin active material coating layers of all-solid-state batteries using a dimensionally reduced formulation…
