I just stumbled on this site... very interesting.
What I found most shocking was the degradation table based on 1yr at various temperatures and SOCs..

Specifically, lithium capacity after one year @
25 degrees C and 40%SOC: 96%
25 degrees C and 100%SOC: 80%
40 degrees C and 40%SOC: 85%
40 degrees C and 100%SOC: 65%
And not too surprising, 60 degrees C *AND* 100%SOC... 60% AFTER 3 MONTHS (!)
Now the Leaf never sees 100% (4.2V) but this makes me wonder how much better 80% (4.05V) is than "full" (4.10V)?
40% btw 3.75V...
Does anyone know of a larger two dimensional table (temperatures, SOC/voltage) showing how fast degradation happens at various temps and voltages?
Preferably for the lithium manganese variety specifically..
