Relation Between Silicon-Based Additives in the Anode and the Gap Between Jelly Roll and Can

graph of Si additive and gap between jelly roll and can in a cylindrical cell design

AION Engineering INC All cells discussed here are 18650 NMC cells. Balancing Energy Density and Safety Using silicon-based additives in the anode requires a delicate trade-off in cell design. While silicon increases the energy density, it also brings significant challenges for cell safety. Why More Space is Needed Silicon expands and contracts during charge-discharge cycling, … Read more

Can-Cap Welding of Structural 4680 Aluminium Cell Can

Speira aluminium can welding

In previous articles we’ve highlighted the benefits of aluminium cell housings for 4680 battery cells like improved thermal management and gravimetric energy density and explored the structural performance of 4680 cans made from Speira ION Cell 3-CB and Speira ION Cell 3-CS1,2,3. It has been shown that high strength aluminium grades like Speira ION Cell … Read more
