Lithium-ion (Li-ion) batteries have emerged as a promising energy source for electric vehicle (EV) applications owing to the solution offered by their high power, high specific energy, no memory effect, and their excellent durability. However, they generate a large amount of heat, particularly during the fast discharge process. Therefore, a suitable thermal management system (TMS) is necessary to guarantee their performance, efficiency, capacity, safety, and lifetime. This study investigates the thermal performance of different passive cooling systems for the LTO Li-ion battery cell/module with the application of natural convection, aluminum (Al) mesh, copper (Cu) mesh, phase change material (PCM), and PCM-graphite. Experimental results show the average temperature of the cell, due to natural convection, Al mesh, Cu mesh, PCM, and PCM-graphite compared with the lack of natural convection decrease by 6.4%, 7.4%, 8.8%, 30%, and 39.3%, respectively. In addition, some numerical simulations and investigations are solved by COMSOL Multiphysics®, for the battery module consisting of 30 cells, which is cooled by PCM and PCM-graphite. The maximum temperature of the battery module compared with the natural convection case study is reduced by 15.1% and 17.3%, respectively. Moreover, increasing the cell spacing in the battery module has a direct effect on temperature reduction.

“…Having a much lower energy density than LIBs, super-capacitors have traditionally been classed as too expensive in Euro/kWh, however their energy storage per kWh requirement is considerably less than LIBs in power applications due in the main to the much lower power capability of the LIBs in kW/kg, which in turn effects the energy density of the storage unit [2]. For portable and mobile devices LIBs are considered to be an ideal technology due to their extremely good energy density, however in the instance of and requirements of regenerative braking to improve both deceleration and acceleration in all types of electric vehicles, the sole or combined use of LIBs or EDLC supercapacitors fall short in their ability to provide instantaneous response in the initial seconds of charge [3],where it is clearly described that to improve the acceleration and deceleration performance of electric vehicles, an application of hybrid energy storage consisting of batteries and super-capacitors or batteries and lithium capacitors is indispensable. It therefore follows that an LIHC, which in effect is a hybrid between LIBs and EDLCs, could form a future solution reliant only on continued improvement of the current energy and power densities.…”

A relative newcomer to the energy storage market, the Lithium Ion Hybrid Super Capacitor is a novel technology breaking new ground in the technology sector. The (LIC) or (LIHC) is fast evolving as the missing link between the Electric Double Layer Capacitor (EDLC) and the Lithium Ion Battery (LIB), being a distinct hybrid of the two technologies. The LIHC combines both energy and power with far longer life and safety features. The use of LIHC capacitors has already woven itself into many industry applications including but not limited to hybrid vehicles, remote area charging solutions, energy harvesting and storage and communications technologies. Mass deployment of LIHCs seems inevitable given the uptake in design processes with the pros outweighing the cons and with higher volume production increasing rapidly. In this paper we will model the Lithium Ion Capacitor characteristics and explore how they perform against an equivalent rival, the standard EDLCwith specific focus on the instantaneous initial charge performance of Lithium Ion Capacitors compared to the other. The focus of this study model is the behaviour of a standard EDLC Super-capacitors Equivalent Series Resistance, "ESR" versus an LIHC Super-capacitor "ESR" of comparable specification in the initial seconds of state of charge.

“…On the other hand, EDLCs have high power densities with a long lifetime that can be charged and discharged quickly but suffer from low energy densities. For instance, some EDLCs supply at least 10 kW/kg of specific power, but at the same time, less than 5 Wh/kg of specific energy [ 6 ]. Gao et al [ 7 ] used EDLCs along with LiBs.…”

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.
