This NASA report on Lithium Ion battery performance is 10 years old and much
has been learned about LiIon batteries since it was written. Despite this it
offers a large amount of rarely seen information about behaviour under
various load and temperature cycling conditions. In particular it provides
insights into the effects of progressively cycling cells at sub zero and
elevated temperatures. (This has a far more pronounced effect on the low
temperature portions of the cyles.) Recommended for extreme battery
treatment enthusiasts.
