“…As a typical embedded electrode material, carbon has the advantages of low cost and wide source, but during the charging and discharging process, carbon materials are prone to structural collapse, resulting in reduced capacity and shortened service life [12][13][14][15][16] . In contrast, alloy-type electrodes, represented by silicon, tin and titanium, achieve energy storage through alloying reactions with lithium ions [11,12,[17][18][19][20]. Alloyed electrode materials have a high theoretical capacity, for example silicon has a theoretical capacity of more than 4200 m Ah g -1 [21].…”

“…The most common types of alloyed materials include silicon-based, tin-based and titanium-based. Alloyed materials have a high capacity, but their volume also changes significantly during charging and discharging, resulting in a short cycle life [11,12,[17][18][19][20]41].…”

“…To address these disadvantages, the preparation of high conductivity composites is the most common approach. Huo et al have synthesized phosphorus-doped TiO2/phosphorusdoped carbon nanofibres (PTO/PC NFs) [19]. The electrostatic spinning method allows for a homogeneous mixing of P in the titanium oxide and carbon nanofibres, while also allowing the PTO nanoparticles to be uniformly embedded in the PC NFs.…”

In recent years, the development and use of new energy sources has become a popular attraction. However, environmentally friendly energy sources such as wind, solar and tidal energy cannot meet the need for a stable energy supply. Therefore, reliable and efficient energy storage systems have received wide attention. Lithium-ion batteries store significant energy per unit volume through electrochemical reactions. Supercapacitors achieve a rapid storage and release of energy by a double electric layer. As a combination of lithium-ion battery and supercapacitor, lithium-ion capacitor has the characteristics of both high specific power and high specific energy, which can complete energy storage and release energy stably with high efficiency. This article introduces the structure of lithium-ion capacitors, including electrode materials, electrolyte and separator. In addition, the common types of electrode materials and the latest research progress are highlighted.

“…On the contrary, lithium-ion batteries (LIBs) can provide prominent energy density (>250 Wh kg −1 ), but the slow Li + diffusion process in the electrode results in a low power density. To achieve high energy and power density, a good long cycle life, and a low cost for energy storage devices, a promising approach is to assemble hybrid device lithium-ion capacitors (LICs) [ 10 , 11 , 12 , 13 , 14 , 15 ]. LICs are made of lithium intercalation/de-intercalation-type anode material, together with capacitive-type cathode material with fast kinetics [ 16 , 17 , 18 ].…”

Lithium-ion capacitors (LICs) are emerging as one of the most advanced hybrid energy storage devices, however, their development is limited by the imbalance of the dynamics and capacity between the anode and cathode electrodes. Herein, anthracite was proposed as the raw material to prepare coal-based, nitrogen-doped porous carbon materials (CNPCs), together with being employed as a cathode and anode used for dual-carbon lithium-ion capacitors (DC-LICs). The prepared CNPCs exhibited a folded carbon nanosheet structure and the pores could be well regulated by changing the additional amount of g-C3N4, showing a high conductivity, abundant heteroatoms, and a large specific surface area. As expected, the optimized CNPCs (CTK-1.0) delivered a superior lithium storage capacity, which exhibited a high specific capacity of 750 mAh g−1 and maintained an excellent capacity retention rate of 97% after 800 cycles. Furthermore, DC-LICs (CTK-1.0//CTK-1.0) were assembled using the CTK-1.0 as both cathode and anode electrodes to match well in terms of internal kinetics and capacity simultaneously, which displayed a maximum energy density of 137.6 Wh kg−1 and a protracted lifetime of 3000 cycles. This work demonstrates the great potential of coal-based carbon materials for electrochemical energy storage devices and also provides a new way for the high value-added utilization of coal materials.
