In the 40 years since the 10811 was designed, AFAIK, there as been zero (0) progress with respect to the capacitance per cubic centimeter of foil capacitors.
I think that's because you're up against physics - foils can only be so thin before the resistance goes up, there's no magic plastic for the dielectric. You get to store a certain number of joules in a given volume of dielectric- you can scale things - reduce the voltage by a factor of 2 and you can get 4 times the capacitance in the same package.
The only way to get higher energy density is to go to a dielectric with higher epsilon, but that brings its own set of problems, especially if you want to stay with solid dielectrics. (there are some interesting energy storage capacitors for short pulses that use water as the dielectric.. that epsilon of 80 is attractive)
