Optimization of battery/ultra‐capacitor hybrid energy storage
Ultra-capacitor has high specific power density; hence, its response time is rapid, that is why it is also referred to as rapid response energy storage system (RRESS). The battery has high energy density; hence, the response is slow and termed slow response energy storage system (SRESS).

Energy Storage | Applications | Capacitor Guide
Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
