What is the difference between a battery and a capacitor?

Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery. This difference comes from batteries being able to store more energy, but capacitors can give off energy more quickly. If a system has a high energy density then it is able to store a lot of energy in a small amount of mass.

Does a battery have a lower power density than a capacitor?

The battery has a lower power density than the capacitor in the flash. This means that the recharge time for the flash is limited by the power output of the battery, rather than the power output of the flash. The energy density of the battery however is higher than the energy density of the capacitor.
