do capacitors store energy quickly

Batteries are like capacitors? : r/ElectricalEngineering

Capacitors store energy in the electrostatic field created between electrodes; no chemical changes are involved. As a consequence, batteries have much higher energy density (J/kg and J/m^3) than capacitors, but the rate of charge and discharge is much slower compared to a capacitor because an electrochemical reaction is required.

The maximum amount of charge you can store on the sphere is what we mean by its capacitance. The voltage (V), charge (Q), and capacitance are related by a very simple equation: C = Q/V. So the more charge you can store at a given voltage, without causing the air to break down and spark, the higher the capacitance.
