The mounting demand for battery cells in the context of the energy transition necessitates evaluation methods that extend beyond technical performance metrics. This work presents a multidimensional framework that simultaneously integrates electrical performance, costs, and life cycle assessment into a consistent analysis of real and virtual cells. In total, 140 cells were modeled, covering commercial chemistries and systematically permuted configurations, in which electrode combinations were recombined. The framework enables a direct variation of individual design parameters without unintended changes to other properties. This allows systematic comparisons of real, commercial cells with virtual redesigns under consistent boundary conditions. The comparison enables the identification of suitable cells in accordance with varying requirements and thus supports cell selection for battery systems.

The mounting demand for battery cells in the context of the energy transition necessitates evaluation methodologies that extend beyond mere performance metrics. This work presents a multidimensional framework that simultaneously integrates electrical performance, economic costs, and life cycle assessment into a consistent analysis of real and virtual cells. In total 140 cells were modeled, covering commercial chemistries and systematically permuted configurations. The framework enables systematic comparisons of real commercial cells and virtual redesigns by varying cell parameters under consistent boundary conditions without unintended side effects. Ultra high energy cells were generated, achieving very high energy densities under idealized design assumptions. Lithium‐iron‐phosphate (LFP) battery cells exhibit global warming potential values of , while sodium‐ion batteries (SiB) show a slightly higher range of . Depending on housing and anode composition, production costs range from – for LFP and – for SiB. SiB cells achieve mineral resource scarcity values of about , three times lower than lithium‐ion batteries. Cathode chemistry proves decisive for ecological performance, with nickel sulfate‐based precursors showing the highest acidification values and LFP cells showing the lowest. Housing design plays an important role: pouch formats minimize costs and emissions. Systematic permutations show that increasing energy density is a key lever to lower environmental burdens.
