Influence of cell dimensions and housing material on the energy
Even though the housing wall for steel cells is only about 0.55 - 0.65 times as thick as it is for aluminum cells (Fig. 2 a)), the density of steel is almost 3 times as large as that of the housing aluminum alloy (Table 1). Therefore, the absolute weight of the housing is in the range of 1.65 - 1.95 times greater for steel cells.

6 FAQs about [4680 Battery aluminum foil thickness]
What is a 4680 battery?
The 4680 battery (46mm in diameter and 80mm in axial length) offers higher energy and power advantages compared to commonly used 18650 or 21700 cylindrical cells. Compared to the 21700 battery, its volume is 5.5 times larger.
What makes a 4680 battery different from a cylindrical battery?
Compared with the previous cylindrical battery, the biggest structural innovation of the 4680 battery is the electrodeless lug, also known as the full lug. In a traditional cylindrical battery, the positive and negative copper foils and the aluminum foil separator are stacked and wound.
What is the capacity of a 4680 cell?
A cylindrical cell that is 46mm in diameter and 80mm high. Capacity tests : 26.5Ah (estimate based on 21700 5Ah volumetric energy density) and this fits with capacity of the Model Y pack that uses this cell. The Laboratory for Energy Storage and Conversion carried out the testing and data analysis of the two 4680 cells reported in this article.
What is the innovative process of 4680 battery?
Conclusion The core innovative process of 4680 battery is: large battery cell + tabless + dry battery technology.
