Electrical equipment and electronic devices with high power density and integration have been developed in recent years. Glass–ceramic materials with high energy storage density, fast charge–discharge capability, and stable high-temperature performance play an important role in obtaining lightweight and miniature electronic components.
Nowadays, the energy storage systems based on lithium-ion batteries, fuel cells (FCs) and super capacitors (SCs) are playing a key role in several applications such as power generation, electric vehicles, computers, house-hold, wireless charging and industrial drives systems.

One electrode--the anode--permits electrons to flow out of it. The other--the cathode--receives them. The energy is stored in the particular compounds that make up the anode, cathode and the
1. Introduction. In recent years, renewable energy has been rapidly used to decrease the dependence on fossil fuels [1] and reduce CO 2 emissions [2].Power generation from variable renewable energy (VRE) is intermittent [3].Thus, energy-storage systems are needed to balance electricity demand and supply [4].Carnot batteries (or
A hybrid energy storage system (HESS) can effectively suppress the high and low-frequency power fluctuations generated by wind farms under the intermittency and randomness of wind.
