Hi.
I read alot of articles and each one mentioned a different
ideal storage voltage for li-ion batteries.
Most of the places mention that the capacity should be 40%,but each one gave different voltage.
One says 3.82V other says 3.7V,third one says 3.6V etc.
In wikipedia https://en.wikipedia.org/wiki/Lithium-ion_battery#Self-discharge)
they recommended not more than 3.6V.
https://cdn.sparkfun.com/datasheets/Prototyping/Lithium Ion Battery MSDS.pdf
It mentioned that the best storage voltage is 3.3v
see figures 20 and 21.
Even though keeping the battery in storage at 3.3v seems to be too low(as they could drop to the unwanted low voltage during long storage),the main point is,as i can understand from those graphs,is that lower storage voltage(as low as 3.3v) is better than 3.6v,3.7v or 3.82v(whatever 40% capacity refer to).
Does someone,but only the experts among you,that know without a doubt:
What is REALLY the ideal storage voltage of li-ion batteries?:shrug:
Thanks in advance.

And at the "lithium ion technical handbook":...Storage of a battery charged to greater than 3.6 V initiates electrolyte oxidation by the cathode and induces SEI layer formation on the cathode...
