What is a modifiable cost model for lithium-ion battery cell chemistries?

Considering the available state-of-the-art bottom-up cost models, Wentker et al. presented a modifiable cost model to estimate cathode active material (CAM) costs for ten sorts of lithium-ion battery cell chemistries based on real-time prices of raw materials.

How to calculate total electrical energy cost in a battery plant?

Hence, the total electrical energy cost in the plant ( ) is calculated based on the needed energy of each unit of the plant to produce one cell ( ) and the unit price for energy ( ). is presupposed as a set index that includes all process steps of battery manufacturing presented in Figure 2 and indicates each process step. 2.2.3.

What is the economic size of a battery cell factory?

Eberhardt et al. reported that 6–8 (GWh/year) is an economic size for the battery cell factory. As mentioned above, expanding the plant capacity from the case study (5.3 GWh/year) to the minimum efficient scale (7.8 GWh/year) decreases the total cost of the cell by around 15.8 (US $ /kWh).

Does the cost model influence the total battery cell production cost?

Since the developed cost model is tied to a large volume of parameters and variables, conducting a sensitivity analysis gives insights into the influence of parameters on the total battery cell production cost. First, the sensitivity of the current cost model to different battery chemistries is examined.

Does micro-level manufacturing affect the energy density of EV batteries?

Besides the cell manufacturing, “macro”-level manufacturing from cell to battery system could affect the final energy density and the total cost, especially for the EV battery system. The energy density of the EV battery system increased from less than 100 to ∼200 Wh/kg during the past decade (Löbberding et al., 2020).

How to develop a battery cell cost model?

Therefore, we develop a battery cell cost model by deploying the PBCM technique. The current cost model is based on a modified battery cell production model already developed by Jinasena et al. to estimate energy and material flow in a large-scale battery cell plant.
