Side reaction rates increase with temperature, but that is only part of the
story. The rates are even more dependent on cell voltage, and Dahn mentions
this:
*• The biggest factor is time spent at highest voltage.
o Longer is worse
o Most of the parasitic reactions happen
Thanks Tomw,
That was a nice video. I didn't hear any contradictions. I learned
somethings about cell construction I did not know.
Dahn was lecturing to explain HPC testing, and Whitacre was lecturing to
help people who assemble and manage packs, so they have a little different
slant.
Why is it you think I am making this up? I have no reason to do anything,
but report what has been found using the new testing. I just read the
papers, talked to the people, and watched that video enough to follow it.
Automotive product validation is pretty rigorous.
Apparently, they did it

I doubt that EnerDel and its customers have overlooked anything as basic as
performance and life at ambient temperatures. It appears to me that Hoegberg is
comparing to some float stand-by application and then misinterpreting the
presented data. But whatever. They have millions of cells in

I am not sure why performance at ambient temperatures should make anyone feel
confident about a cell. LFP for instance, starts to have serious difficulties
at 104°F if it is fully charged.

also notice they have very good cold weather performance. I have some PDF

Hello EVDL,
EnerDel makes a great cell and battery here in the USA. I have been to
their factory in the Indianapolis area many times. I use the product
just about every day. I can write more but want
them a visit.
