With few exceptions, all chemical reactions happen faster at higher
temperature. Thus, all batteries, including lithium-ion, age more
quickly at elevated temperature.
There is no magic about 86 degrees. The hotter they are, the
quicker they age. Chemical reactions are (generally) governed by
the Arrhenius equation.

I came across this article today mentioning that Lithium Ion battery
life starts to degrade faster above 86 degrees Fahrenheit. This was
delivered by a Dr. Cugnet at the 245^th National Meeting &
Exposition of the American Chemical Society (ACS). I am skeptical
that this applies to all Lithium ion chemistries. Does anyone know
of Dr. Cugnet and what he is espousing??
