“…UCs are gaining popularity in many industries as a reliable energy storage device because of their specific properties: larger capacitance, high power density, high energy density, and fast charging. Among existing UC-based storage technologies [4][5][6][7][8][9][10], symmetric double-layer UCs [5] and asymmetric Li-ion hybrid UCs [6][7][8] exhibit superior behavior to that of others. Alizadeh et al showed that the application of UCs improves the performance of microgrid frequency regulation as a result of improved virtual system inertia [11].…”

Electrical storage components such as ultracapacitors (UC) have received significant attention from various industrial sectors, from electric vehicles to renewable power plants. This article presents the investigations on dynamic properties of asymmetric Li-ion hybrid (CPQ2300S: 2300 F, 2.2-3.8 V, JSR Co., Tokyo, Japan) and symmetric double-layer (BCAP3400: 3400 F, 2.85 V, Maxwell Technologies Co., San Diego, CA, USA) ultracapacitors. The internal resistance and capacitance of both UCs were slightly changed with respect to current and voltage alterations, but these changes were more prominent for the Li-ion UC. The internal resistance of the Li-ion UC became five times larger and its capacitance decreased significantly when the temperature decreased from +25 • C to −20 • C. More importantly, the double-layer UC exhibited nearly constant capacitance for a wide range of temperature changes (0 • C to −40 • C), although internal resistance increased somewhat. Electrochemical impedance spectroscopy analysis of both UCs was performed for the frequency range of 1 Hz-1 kHz and in the temperature range from −15 • C to +30 • C. It was observed that the temperature effects were much more pronounced for the asymmetric Li-ion UC than that of the symmetric double-layer UC. This work also proposes an improved equivalent circuit model based on an infinite number of resistance-capacitance (r-C) chains. The characteristic behavior of symmetric UCs can be explained precisely by the proposed model. This model is also applicable to asymmetric UCs, but with less precision. similar asymmetric UCs are also applicable to pulsed electric power sources [12,13]. Piórkowski et al. presented a case study about the application of UCs in hybrid systems including an engine start module (ESM), a photovoltaic (PV) module, a battery, and an internal combustion engine (ICE) [14]. In continuation, the hybrid model control strategy was proposed for a double active bridge-based supercapacitor energy storage system [15]. More importantly, the service lifetime of UCs is three times higher compared to electrochemical storage batteries (e.g., Li-ion or lead-acid) although UCs are relatively bulky and voluminous [16]. Consequently, there is a lack of accurate information regarding the ability of Li-ion UCs to provide voltage and current during charge-discharge cycles. Previously, a significant number of experimental investigations were carried out [16][17][18][19][20][21][22] in order to understand the characteristic behavior of UCs. Different direct measurement methods for the evaluation of UC parameters were also proposed [16][17][18][19][20]. A comprehensive review of characterization methods for supercapacitor modeling and general parameter identification techniques were also discussed [21,22].A significant amount of effort has been made to describe dynamic UC behavior using different types of equivalent circuits [23][24][25][26][27][28][29][30]. Some works presented modeling approaches based on electrochemical explanations of UC performance [31][32][33...

“…In addition, the LIB energy storage system has been proposed for use in a newly designed DC line interactive UPS because of the high rate pulse discharge capability of LIBs (up to 10 C for less than 10 s), which is attractive for load leveling service in the 150 kVA UPS system of a medical imaging machine. The proposed system has two modules that consist of 54 LIBs, each providing 170 V and pulsed peak (less than 5 s) power of 75 kW [55,56].…”

In the electrical energy transformation process, the grid-level energy storage system plays an essential role in balancing power generation and utilization. Batteries have considerable potential for application to grid-level energy storage systems because of their rapid response, modularization, and flexible installation. Among several battery technologies, lithium-ion batteries (LIBs) exhibit high energy efficiency, long cycle life, and relatively high energy density. In this perspective, the properties of LIBs, including their operation mechanism, battery design and construction, and advantages and disadvantages, have been analyzed in detail. Moreover, the performance of LIBs applied to grid-level energy storage systems is analyzed in terms of the following grid services: (1) frequency regulation; (2) peak shifting; (3) integration with renewable energy sources; and (4) power management. In addition, the challenges encountered in the application of LIBs are discussed and possible research directions aimed at overcoming these challenges are proposed to provide insight into the development of grid-level energy storage systems.

“…The main drawback of this ECM is depiction of the cell dynamics only for a short period of several seconds. Figure 8 d demonstrates an ECM for power electronics applications that consist of five parameters [ 55 ]. One of the model parameters is the capacitance that depends highly on voltage variations to reduce the simulation time.…”

This review paper aims to provide the background and literature review of a hybrid energy storage system (ESS) called a lithium-ion capacitor (LiC). Since the LiC structure is formed based on the anode of lithium-ion batteries (LiB) and cathode of electric double-layer capacitors (EDLCs), a short overview of LiBs and EDLCs is presented following the motivation of hybrid ESSs. Then, the used materials in LiC technology are elaborated. Later, a discussion regarding the current knowledge and recent development related to electro-thermal and lifetime modeling for the LiCs is given. As the performance and lifetime of LiCs highly depends on the operating temperature, heat transfer modeling and heat generation mechanisms of the LiC technology have been introduced, and the published papers considering the thermal management of LiCs have been listed and discussed. In the last section, the applications of LiCs have been elaborated.
