Does a high energy density mean a low power density?

If a system has a high energy density then it is able to store a lot of energy in a small amount of mass. A high energy density does not necessarily mean a high power density. An object with a high energy density, but low power density can perform work for a relatively long period of time.

Why does a system have a high power density?

If a system has a high power density, than it can output large amounts of energy based on its mass. For example, a tiny capacitor may have the same power output as a large battery. However, since the capacitor is so much smaller, it has a higher power density.

What is the difference between energy density and power density?

Energy density is the amount of energy in a given mass (or volume) and power density is the amount of power in a given mass. The distinction between the two is similar to the difference between Energy and power. Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery.
