Do material prices affect the cost structure of a lithium-ion battery cell?
By discussing different cell cost impacts, our study supports the understanding of the cost structure of a lithium-ion battery cell and confirms the model’s applicability. Based on our calculation, we also identify the material prices as a crucial cost factor, posing a major share of the overall cell cost.
Are cylindrical cells cheaper than prismatic Li-ion cells?
No published manufacturing models compare the cost of cylindrical and prismatic Li-ion cells. However, we present a process-based cost model for specified cylindrical cell dimensions. Economies of scale have already been reached in cylindrical cell manufacturing. Larger cells or cells with thicker electrodes offer a lower cost per kWh.
Does battery design change to tabless electrodes in cylindrical cell affect production costs?
This study demonstrates how the battery cell design change to tabless electrodes in cylindrical cell influences the productions costs in a large-scale manufacturing context. A bottom-up cost calculation approach, focussing on the production process changes, allows us to individually study the effects on different cost categories.
Does cell chemistry affect the per kWh cost of lithium-ion batteries?
The per kWh cost of lithium-ion batteries is significantly affected by cell chemistry in the process-based cost model for cylindrical lithium-ion cells. For instance, LMO batteries, which have a low specific energy, are too small in the cylindrical cell format and cannot accommodate sufficient electrode thickness.
What is a battery chemistry cost model?
It calculates battery cell and pack costs for different cell chemistries under a specified production volume within a pre-defined factory layout and production process. The model is frequently used, adapted, or extended by various authors 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.
Are cylindrical cells cost based on prismatic cells?
There is no specific model to address the costs of manufacturing cylindrical cells, as manufacturing process research and cost models have focused exclusively on prismatic cells.
