@NavyCuda Looking at some of your old posts, you live in Canada. That's likely why you've seen little impact with charging to 100% all the time. Also, as I mentioned, charging to 100% when it's not hot out and then driving the LEAF shortly thereafter won't hurt the battery. Heat is the enemy of the battery pack.
@Foschas seems to live in Kingston, MA which isn't a hot climate either.
Someone in Texas or Arizona and charging to 100% SOC all the time will not be so lucky, particularly if they charge when it's hot out or park the car in the heat with a high SOC. No battery chemistry tweaks are going to fix that. Just look at 30 kWh battery pack degradation issues for confirmation of that.http://batteryuniversity.com/learn/arti ... ion_to_die

The manganese-based Li-ion batteries chosen for the Nissan Leaf and other EVs have excellent lab results. What may have been overlooked in the Nissan Leaf test is the damage that is being done when keeping the battery at high voltage and elevated temperature. As the coulombic efficiency tests reveal, these two conditions can cause more damage than cycling
The main conclusion that can be drawn regarding degradation is that temperature is the most influencing factor in cycle ageing as well as calendar ageing. The temperature of cells will be dependant on ambient temperature and current. State of charge level will also influence the degradation, but generally to a lesser extent than temperature. It is better to store a lithium-ion battery with a low state of charge rather than a high level. If possible it also good to keep the state of charge low at usage with small deviations. This may not be possible for all applications, especially not for BEVs as it will impede range
