1. Durable cycle life. Supercapacitor energy storage is a highly reversible technology. 2. Capable of delivering a high current. A supercapacitor has an extremely low equivalent series resistance (ESR), which enables it to supply and absorb large amounts of current. 3. Extremely efficient.
The second type of thermal energy storage is sensible heat storage, stores energy in a medium without inducing a phase change. Sensible heat storage can be classified into low temperature storage, which operates at temperatures below 100°C, while high temperature storage operates at temperatures which exceed 100°C [7].
