A Comprehensive Review of Graphene-Based Anode Materials for Lithium-ion Capacitors

Abstract

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.

Graphene: Chemistry and Applications for Lithium-Ion Batteries

“…Graphene is also specified as graphene nanosheets (GNS) and is widely explored as the negative electrodes for energy storage devices. The theoretical specific capacity of graphene is reported to be 744 mAh g −1 which is twofold than that of the 3D graphite (372 mAh g −1 ) [31]. Initial reports on graphene nanosheets based anode for LIBs were reported by Honma et al [32] in 2008, wherein they compared the performance of graphite with graphene nanosheets, graphene nanosheets composites with CNT, and fullerene.…”

Progress in electrode and electrolyte materials: path to all-solid-state Li-ion batteries

“…Different kinds of carbon materials, including amorphous carbon (a-C), graphite, carbon nanotubes (CNTs), carbon nanofibers, etc., [99,179]. have been investigated to improve the cycling stability of Si active materials.…”

“…Dispersing Si in a carbon matrix has been well-developed in which the carbonaceous materials can buffer the volume change and improve the electrical conductivity of Si active materials. Different types of carbon materials, including amorphous carbon (a-C), graphite, carbon nanotubes (CNTs), carbon nanofibers, 102,181 have been investigated to improve the cycling stability of Si active materials. The specific capacity, Coulombic efficiency, and scanning rates of C-based anode electrodes are summarized in Table 9.…”

Review of Boron Compounds in Lithium Batteries: Electrolyte, Anode, Cathode, Separator, and Battery Thermal Management System (BTMS)

“…Due to its larger specific area and physical strength, graphene was studied as an alternative anode material to improve the capacity retention and cycling performance of graphite [46,47]. Graphene anodes could help to overcome the challenge of LIBs, that is, having the advantage of high power density (energy discharge rate) but the relative disadvantage of low energy density (amount of energy stored) [48]. A lithium iron phosphate (LFP) system could be a classic example of that.…”
