To quote the paper :
"the dipoles can be rapidly aligned at 100°C by an ac applied electric field and frozen into alignment at 25°C < Tg. "
Has consideration been given (experimentation as well) within the laboratory environment to the behavior of the glass substrate within extreme naturally occurring temperatures. While, my personal property values increase proportionately with the effectiveness of global warming and hope at some point to own luxury resort beach front property here in Oslo, Norway, it's not uncommon to operate an EV within sub -20C temperatures and with -50C temperatures further north.
Current Li based cells suffer badly within these climates. In addition, in the past working together with Lee (Elias) Stefanakos Ph.D. from USF, we experienced in Florida certain behaviors in higher unregulated temperatures (with regards to lead-acid cells.. circa 1993) behavioral degradation of chemical electrolytes at +37C (if I recall correctly).
How does your and Maria's solid-state substrate behave within extreme temperatures. While I certainly am no material's scientist, I am curious whether there are behavioral symptoms displayed when performing under such naturally occurring extremes.
In addition, fluid electrolytes can often "self-repair" under these circumstances as a result of "reflowing". If these negative behaviors are apparent in within the solid electrolyte, are the damages sustained (structural fractures for example) or does the substrate display typical expansion and contraction under naturally occurring conditions?
For a bonus :) If the substrate reaches 100C again, what appears to be the behavior? Does it depend on a rapid decrease or "flash freeze" to 25C to stabilize the structure? Will it render the cell absolutely useless? Will it simply continue "business as usual"?
