Back in the dark ages !

The answer is not as simple as yes/no
At DC the answer is NO
At RF the answer varies with frequency.

I've read that charging lithiums with an ordinary alternator can smoke your alternator. Investigate before doing that.

You were taught correctly, but the difference is negligible. What matters more is the operating temperature of the wire. The cooler the wire is, generally, the more current it will carry. (less voltage drop) Stranded wire, because it has more surface area per foot than solid wire can shed or gain heat more easily than solid wire depending on the ambient temperature and the insulation. Stranded wire has much more flexibility (resistance to vibration) than solid core wire of similar gauge, that's why you generally see its use in aerospace, automotive, and industrial applications.

As the temperature approaches absolute zero (-460 degrees F) wire conductors approach zero resistance. They become superconductors where current flows with little to no voltage.

Guy next door sez that I should not let the alternator on my truck charge my lithium while driving . Is he a dummy ?

A shunt is a small resistance inserted in line with the load

Small in "value", but large in size.

other way around solid wire will carry more current than stranded wire of the same size due to air gaps between the strands and stuff.

Well, that is the simple explanation given to me by electricians!

Solid wire is cheaper to make and easier to connect in household wiring. Stranded wire is better where flexibility is important such as lamp cords or in vehicles.

Thank you for being our mythbuster this morning for the electrically challenged.

There is a small difference in max current. The bigger issue is solid wire is more prone to failure over time.
