What is a battery cell cost model?

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. Section 2 provides a brief explanation of the production model, proceeding with a detailed study of the design and calculation of the cost model.

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.

How much does construction cost affect battery cell cost?

Assuming a 25% increase or decrease in the construction cost of the buildings in the battery manufacturing plant can change the final battery cell cost by, at most, 2.3%, while the same assumption for the labor wage can alter the battery cell cost, on average, by 8.2%.

What is a per unit battery cell cost?

The per-unit battery cell cost ( ) is the summation of defined cost layers. Thus, It is worth mentioning that since the units in this work are based on US $ /kWh, the total battery cell cost ( ) is divided by the product of specific energy of battery cell ( ) and mass of cell ( ) to the output (US $ /kWh) unit. 3. Results and Discussion

Could a new production technology reverse the declining battery cell production costs?

The findings reveal a noteworthy prospect: the existing production technology could potentially reverse the declining battery cell production costs, contingent upon the high trajectory of essential metal prices.

How does location affect the cost of battery cell production?

For a case study plant of 5.3 GWh.year −1 that produces prismatic NMC111-G battery cells, location can alter the total cost of battery cell production by approximately 47 US $ /kWh, which is dominated by the labor cost.
