Comparative Cost Modeling of Battery Cell
As lithium-ion batteries increasingly become a cornerstone of the automotive sector, the importance of efficient and cost-effective battery
Large cylindrical batteries feature a steel casing with 550MPa strength—5.5 times that of prismatic aluminum casings (95MPa). Combined with a 1500MPa dual-layer hot-formed steel bottom design and 3500MPa aerospace-grade fiberglass, they achieve crash energy absorption of 1000J—6.6 times the national standard.
Here, we can see that the manufacturing efficiency of large cylindrical batteries at 300 PPM is 10 times that of prismatic cells, while our manufacturing steps have been further reduced to 10 steps, shortening the production cycle to 7 days.
The cost saving potential of large-format tabless cylindrical lithium-ion cells has been widely recognized since Tesla announced their plans to produce and BMW has confirmed to adopt this type of cells due to economic benefits among other reasons.
1. Introduction Large-format cylindrical lithium-ion cells have been widely discussed in recent years since Tesla announced their 4680 cell with 46 mm diameter and 80 mm height . Especially the tabless electrode design enables cells with larger dimensions through enhanced current collecting and thermal pathways,,, .
