Lucid Group Inc. (LCID) CEO Peter Rawlinson believes Tesla Inc’s new 4680-type cylindrical cell format is not a “huge breakthrough,” IEEE spectrum reported, citing the executive.
What Happened
Rawlinson believes that the larger format and new design have some advantages but it is more a “triumph of packaging” due to its tightly packed “jelly rolls” that allow more active cell material versus its surrounding casing, rather than a chemistry breakthrough.The former Tesla employee said the benefits include reduced internal resistance and higher energy density and that’s a “valuable step forward.”
