What is the difference between energy density and power density?

Solution

Energy density Power density
Energy density tells us the amount of energy stored in a unit battery.
The total amount of energy in a system per unit volume is defined as energy density.
For example, in the case of a battery and capacitor, batteries have a higher energy density.
This is because batteries are good at storing energy.
Power density signifies the amount of energy that a unit battery can supp
The amount of power (time rate of energy transfer) per unit volume is referred to as power density.
For example, in the case of a battery and a capacitor, Capacitors have a higher power density than batteries.
This is because a capacitor discharges energy in the circuit.
