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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
