Why are capacitors treated as shorts in small signal models?

If I understand correctly, a small signal model (e.g. hybrid pi modal of MOSFETs) is just a linear approximation of a nonlinear circuit centered at the DC bias point. At DC, ideal capacitors act like $begingroup$ @Mikayla, Your first sentence is extremely well-written! @Mikayla, Your first sentence is extremely well-written!

Supercapacitors: A new source of power for electric cars?

When supercapacitors are coupled to batteries, the capacitors are able to supply the peak power demands of acceleration in a lighter package, offsetting the need for extra battery mass. Each additional kW required can be supplied by a supercapacitor in a package 10–20 times lighter than a lithium battery counterpart.
