Yes, I am aware of that. For about 5 years I have been advising people not to charge to over around 3.45V which is about where the exponential increase in the curve starts at typical charge currents. I published a number of cell measurements and charge curves around that time showing there is less than 2 Ah charge between 4.45V and 3.55V on 180Ah cells, so not much gain in charge by going there unless you use a shunt balancing BMS which I do. Shunt turn-on varies from 3.48V to 3.52V over my 36 cells, so every 4 - 6 charges I charge the highest cells to 3.54 - 3.55V and check the shunt LEDs to ensure they are all on giving me peace of mind that the pack is still balanced. The rest of the time I just do partial charges. Many people only charge to less than 3.45V every charge. No one I know of charges fully. The manufacturer's spec is final CV charge at 0.05C to 3.6V which is below the maximum voltage for the cells. You also have to keep in mind that although there are significant differences in the rates of side reactions in cells of different chemistries, the rates are fairly low, so the effects accumulate slowly over years unless you significantly over charge or discharge a cell. I don't think anyone expects these prismatic cells to last 10 or more years with less than 10% capacity loss. I'll be happy if my pack still has 90% nominal capacity in 7 years, which is only 1 1/2 years away. Then I'll replace it with a wrecked Leaf 30kWh pack :^)
