1D Isothermal Sodium-Ion Battery

Application ID: 117341


Sodium-ion batteries (SIB) are commonly presented as an alternative to lithium-ion batteries (LIB).

The SIB chemistry uses Na+ instead of Li+ for electrolyte charge transport and as redox species in the electrode reactions, with the advantage of Na+ being more abundant and with a potentially smaller environmental footprint than Li+ during production. SIBs however typically exhibit lower energy densities than LIBs, and hence constitute a candidate for replacing LIBs mainly in stationary applications.

The SIB chemistry has many similarities to the LIB chemistry, and can often be described by the same equations for charge and mass transport, electrode kinetics, and electrode particle intercalation. This model example demonstrates how to use the Lithium-Ion Battery interface for modeling a SIB.
