“…For example, in LICs, the metal Si anode presented a theoretical Li‐storage capacity as high as 3579 mAh g −1 and the metal Sn anode performed a Li‐storage theoretical capacity up to 994 mAh g −1 . [ 118,119 ] Although the Sn, Sb, Si, and Bi alloy materials and their compounds have been widespread used in EES devices, the serious volume expansion and terrible cycle stability restrict their further development. Recently, the strategy of nanocrystallization, coating, and compositing with other materials is utilized to surmount the aforementioned shortcomings.…”

Electrochemical energy storage (EES) devices with high‐power density such as capacitors, supercapacitors, and hybrid ion capacitors arouse intensive research passion. Recently, there are many review articles reporting the materials and structural design of the electrode and electrolyte for supercapacitors and hybrid capacitors (HCs), though these reviews always focus on individual supercapacitors or single HCs. Herein, the conventional capacitor, supercapacitor, and hybrid ion capacitor are incorporated, as the detailed description of conventional capacitors is very fundamental and necessary for the better understanding and development of supercapacitors and hybrid ion capacitors, which are often ignored. Therefore, herein, the fundamentals and recent advances of conventional capacitors, supercapacitors, and emerging hybrid ion capacitors are comprehensively and systematically summarized in terms of history, mechanisms, electrode materials, existing challenges, and perspectives. At the same time, it is believed that a comprehensive and fundamental understanding for capacitor‐related EES devices is provided in the review and has a great guiding role for future development.

“…Particularly, graphene, with merits of stable and flexible 2D sheets, large SSA, a high electrical conductivity, has been applied to form composites with these alloyin type materials and develop high-performance anodes for LICs [132,133]. For examp Jiang et al constructed a 3D conductive framework of graphene aerogel supported nanoparticles (Si@GA) through a hydrothermal reaction of GO and SiO2 followed magnesiothermic reduction (Figure 12a) [134]. As shown in Figure 12b, Si particles almost fully encapsulated by graphene to form a 3D conductive composite with hi surface area and abundant pores, which not only buffers the severe volume expansion Si but also facilitates electron transfer and rapid electrolyte penetration and diffusi Consequently, the optimal composite (Si@GA-2) exhibited outstanding rate capabil with reversible capacity of 1327.3 and 551.9 mAh g −1 at 0.1 and 5 A g −1 , respectively (F ure 12c,d).…”

Lithium-ion capacitors (LICs) are considered to be one of the most promising energy storage devices which have the potential of integrating high energy of lithium-ion batteries and high power and long cycling life of supercapacitors into one system. However, the current LICs could only provide high power density at the cost of low energy density due to the sluggish Li+ diffusion and/or low electrical conductivity of the anode materials. Moreover, the serious capacity and kinetics imbalances between anode and cathode result in not only inferior rate performance but also unsatisfactory cycling stability. Therefore, designing high-power and structure stable anode materials is of great significance for practical LICs. Under this circumstance, graphene-based materials have been intensively explored as anodes in LICs due to their unique structure and outstanding electrochemical properties and attractive achievements have been made. In this review, the recent progresses of graphene-based anode materials for LICs are systematically summarized. Their synthesis procedure, structure and electrochemical performance are discussed with a special focus on the role of graphene. Finally, the outlook and remaining challenges are presented with some constructive guidelines for future research.
