Cylindrical lithium-ion battery cells are a type of rechargeable battery commonly used in a wide range of electronic devices, electric vehicles, and energy storage systems. They are characterized by their cylindrical shape, standardized sizes, and high energy density, making them versatile and suitable for various applications.
For instance, “65” represents a height of 65mm. Fifth Digit: The fifth digit indicates the cylindrical shape of the cell. Typically, it’s “0” for cylindrical cells. By following this naming convention, we can easily identify the size and shape of cylindrical lithium-ion battery cells.
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.
The process-based cost model we construct for cylindrical lithium-ion cells shows that the cell chemistry has a significant impact on the per kWh cost of the batteries. For LMO batteries, with a low specific energy, the cylindrical cell format is too small and does not allow for the electrode thickness to increase sufficiently.
Like prismatic cells, lithium prices play a small role in the cost of NMC and NCA cylindrical cells. A more than 200% increase in the price of lithium carbonate leads to a less than 10% increase in the cost per kWh for each of the cell configurations considered. Cell hardware is a significant contributor to the overall material cost per kWh.
The naming rules for cylindrical lithium-ion battery cells follows a standardized format based on the cell’s dimensions, and usually represented by a five-digit code, where each digit provides specific information about the cell’s dimensions. Here’s a breakdown of the representation: What does 18650 means?
