There is hope for cold weather Lithium batteries

"Date: February 25, 2021 Source: University of California - San Diego Summary: Nanoengineers have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius."

I wonder if that will increase the self-discharge rate. Honestly, that might be a good thing if it's not excessive... the batteries would need a float charge, which would make them even more suitable for FLA/AGM/GEL drop-in replacements.

My questions are capacity and size? What will this do to the C rate?
