Increase in specific energy, gravimetric density, by using the dry process, means, most likely, more amp hours per cell, not a voltage change.This is something I'm actually not clear on. Yes, it would make sense to retain a pack design that's proven while just replacing the cells. However, based on my understanding, the dry electrode manufacturing process improves the gravimetric energy density. But does this directly translate to a higher energy capacity per cell? Or would it simply make the cell lighter while keeping the same energy capacity? Would the cell-level voltage or current change? Because retaining the pack design would mean the number of cells per pack remains constant, so you wouldn't be able to simply jam more cells into the same modules.
Someone with a better understanding of battery cell parameters than me could possibly contribute here...
