Among them, the Li-ion hybrid supercapacitor has better comprehensive performances which could be one of the most important candidates to be studied and promoted in the future. Table 1. The method of hybrid, specific capacitance (C s), energy densities (E s), power densities (P s) and potential window of the three kinds of hybrid devices.
As stated earlier, the major disadvantage of supercapacitor devices when compared with batteries is lower energy density, which in turn depends on capacitance and operational voltage . To achieve it, high-performance electrolytes that operate in a wider potential window are required in addition to the electrode material with higher capacitance.
To meet the demands of all kinds of multifunctional electronics which need energy storage systems with high energy and power densities, the hybridization of batteries and supercapacitors is one of the most promising ways.
In such a case, supercapacitor-battery hybrid energy storage can handle the voltage and frequency stability by supplying the auxiliary power from the battery and transient power from the supercapacitor . In microgrids maintaining a DC bus requires less complexity than maintaining an AC bus because it is efficient and cost-effective.
After the simulations and analysis, many researchers have found that the voltage stability has improved after connecting the supercapacitor module to the microgrid. For example, a dynamic voltage restorer of a supercapacitor-battery hybrid system is regulated by a predictive control method to compensate the voltage sag and swell .
Conclusions and outlooks With the development of the world economy, the demand for energy storage systems which possess high energy and power densities is increasing. Hybrid supercapacitors have been widely studied due to their higher power densities compared to batteries and higher energy densities compared to SCs.
