Techno-Economic Evaluation of Solid-State and Sodium-Ion Batteries in E-Mobility Using a MATLAB Tool

The selection of suitable battery technologies is a key lever in shaping the global transition to sustainable mobility. This study investigates the techno-economic potential of two emerging battery types – solid-state batteries and sodium-ion batteries. While solid-state batteries promise higher energy densities, sodium-ion batteries offer advantages in material availability and potential cost stability due to the abundance of sodium. A MATLAB-based evaluation is used to conduct a holistic analysis focusing on their application within the Tesla Model Y and the VW ID.3. The assessment considers key indicators such as energy density, specific costs, CO2 emissions, and achievable driving range. The results highlight technological trade-offs and demonstrate how different battery choices impact the ecological and economic performance of electric vehicles. Moreover, the flexibility of the modeling approach enables its application across a range of current and future vehicle configurations, supporting strategic decision making in battery selection.
