When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates. To gain insight into how this energy may be expressed (in terms of Q and V), consider a charged, empty, parallel-plate capacitor; that is, a capacitor without a dielectric but with a vacuum between its plates.
Compared to batteries, capacitors have a lower energy density, storing less energy per unit of volume or mass. This makes them less suitable for long-duration energy storage. Another key difference is the self-discharge property: capacitors tend to lose their stored energy relatively quickly when not in use.
