According to data presented by Tesla, the 4680 large cylindrical lithium battery increases energy density by five times compared to the 21700 cylindrical cells, enhances mileage by 16%, and reduces costs by 14%.
What are the advantages of a lithium battery?
RELiON lithium batteries offer several advantages over traditional flooded, AGM, or GEL lead-acid batteries. They typically weigh one-third less and provide up to 50% more energy than these other types. Additionally, lithium batteries provide more power and have super-low resistance (and 99% efficiency), allowing for much faster charging with minimal losses.
What is a large cylindrical 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.
The increasing adoption of lithium-ion batteries is observed due to their capacity to hold significant power in small size and lightweight bodies. However, lithium batteries have a risk of being outcompeted by other advanced technologies such as zinc batteries, flow batteries, and high-temperature batteries among others.
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.
Compared to prismatic cells, the zero-swelling characteristic of large cylindrical batteries guarantees consistent performance throughout the entire lifecycle, rendering stress management obsolete. Drive with Confidence
The circular geometry of large cylindrical batteries ensures uniform stress distribution from the beginning to the end of their lifecycle, eliminating axial swelling entirely.
