“…However, during the synthesis process, these methods led to the formation of buckyball-like nanoparticles or nanotube of MoS 2 (Rosentsveig et al, 2001;Rapoport et al, 2005). An effective way to resolve this issue and to get the layered structured MoS 2 is to employ carbon materials such as graphene, as a template (Chang and Chen, 2011;Hwang et al, 2011;Li et al, 2011;Wang et al, 2018;An et al, 2019;Li et al, 2019b). The graphene impedes the formation of three dimensional MoS 2, resulting in the 2D growth of MoS 2 on graphene nanosheets during the synthesis process (Chang and Chen, 2011a;Hwang et al, 2011;Li et al, 2011).…”

“…Due to its low lithiation ability (<0.5 V) and strong real theoretical efficiency (4200 mAh g−1), Si is a promising material for high-performance LIC anodes [108,109]. Despite its excellent load-discharge platforms and extremely high specific capacity, its cycling and rate performance may be poor due to its severe volume expansion and low electronic and ionic conductivity [110]. Furthermore, due to its inherent semi-conductive design, the low conductivity may also restrict its performance in charge/discharge at high current density [111][112][113].…”

“…Therefore, using a small amount of silicon-carbon composite in a soft carbon anode could ameliorate the anode's charge/discharge kinetics and also provide surplus lithium to slow the rate of active lithium consumption in long-term cycling after anode pre-lithiation. Using this approach, it has been observed that such a LIC has over 95% capacitance retention after 10,000 cycles at 20 °C [110].…”

Lithium-ion capacitors (LICs) have gained significant attention in recent years for their increased energy density without altering their power density. LICs achieve higher capacitance than traditional supercapacitors due to their hybrid battery electrode and subsequent higher voltage. This is due to the asymmetric action of LICs, which serves as an enhancer of traditional supercapacitors. This culminates in the potential for pollution-free, long-lasting, and efficient energy-storing that is required to realise a renewable energy future. This review article offers an analysis of recent progress in the production of LIC electrode active materials, requirements and performance. In-situ hybridisation and ex-situ recombination of composite materials comprising a wide variety of active constituents is also addressed. The possible challenges and opportunities for future research based on LICs in energy applications are also discussed.

power densities (<1000 W kg −1) that cannot satisfy the requirements for applications that need the power sources being rapidly charged. [3] Instead, EDLC can store energy in extreme short period and subsequently release burst of energy when needed, through the fast surface redox reactions or fast physical electrolyte ion adsorption/desorption. [4] However, the relatively low energy densities of EDLCs (1-2 times lower than those of LIBs, <10 Wh kg −1) inevitably hinders the large-scale practical applications. [5] Confronted with the abovementioned challenges, integration of battery-type and capacitive charge storage in one cell is in great demand because of the nearly eliminating gap between LIBs and EDLCs, [6] at the same time, achieving high energy-power density as well as long-term cycling life. [7] In year 2001, the lithium ion capacitor (LIC) with Li 4 Ti 5 O 12 and activated carbon (AC) as electrode materials was first proposed and exhibited the distinctive energy density of 20 Wh kg −1 , 3 times of magnitude higher than conventional EDLCs. [8] Afterward, the LICs with diverse electrode materials have been extensively studied and successfully commercialized in recent years, which also make great contributions to the fields of wind-power generation, short-time power outage compensation devices, hybrid industrial machinery, microelectric vehicles, [9] and so on. Nevertheless, due to the limited resource reservation in nature and geographically inhomogeneous lithium element distribution in addition to a large scale of application of LIBs, [10] the high cost and availability of lithium have arisen significant concerns among the researchers and specialist community. The prelithiation technique in LICs also consumes lithium element to make sure the realization of excellent electrochemical performance. Sodium element shows similar physical and chemical properties with lithium element, and importantly, the crust content of sodium species is richer than that of lithium species, leading the cost of sodium much lower than that of lithium. [11] Furthermore, the sodium ion presents a larger radius (1.02 Å) and weaker solvation energy than those of lithium ion (0.76 Å), tending to deliver pseudocapacitive processes, which is beneficial to capacitors. Therefore, the energy storage systems based on sodium species deliver lower cost along with higher competitiveness, and accordingly become a good supplement to the energy storage system based on lithium species. [12] High-efficiency energy storage technologies and devices have gained numerous attention because of their ever-increasing requirement. Sodiumion capacitors (SICs), as a burgeoning electrochemical energy storage device, combine virtues of rechargeable batteries and electrochemical double layer supercapacitors, delivering both high energy-power density and long cycling life. In the past decades, great efforts have been made to find suitable anode material to conquer the kinetic imbalance between the battery-type anode with sluggish bulk redox reaction and the capaci...
