“…The nanocomposite was tested as an anode in button lithium-ion battery giving a high energy capacity, yet it still suffered from a short life cycle, suggesting further studies on the stability of Si-NPs/graphene nanocomposite. Saulnier et al also studied the use of multilayer CVD grown graphene on nickel substrate as the anode material [ 271 ]. The effect of films’ morphological defects on the sustainability of discharge capacity at high speed was highlighted.…”

Graphene as the 2D material with extraordinary properties has attracted the interest of research communities to master the synthesis of this remarkable material at a large scale without sacrificing the quality. Although Top-Down and Bottom-Up approaches produce graphene of different quality, chemical vapour deposition (CVD) stands as the most promising technique. This review details the leading CVD methods for graphene growth, including hot-wall, cold-wall and plasma-enhanced CVD. The role of process conditions and growth substrates on the nucleation and growth of graphene film are thoroughly discussed. The essential characterisation techniques in the study of CVD-grown graphene are reported, highlighting the characteristics of a sample which can be extracted from those techniques. This review also offers a brief overview of the applications to which CVD-grown graphene is well-suited, drawing particular attention to its potential in the sectors of energy and electronic devices.

All-solid-state batteries (SSBs) are one of the most fascinating next-generation energy storage systems that can provide improved energy density and safety for a wide range of applications from portable electronics to electric vehicles. The development of SSBs was accelerated by the discovery of new materials and the design of nanostructures. In particular, advances in the growth of thin-film battery materials facilitated the development of all solid-state thin-film batteries (SSTFBs)—expanding their applications to microelectronics such as flexible devices and implantable medical devices. However, critical challenges still remain, such as low ionic conductivity of solid electrolytes, interfacial instability and difficulty in controlling thin-film growth. In this review, we discuss the evolution of electrode and electrolyte materials for lithium-based batteries and their adoption in SSBs and SSTFBs. We highlight novel design strategies of bulk and thin-film materials to solve the issues in lithium-based batteries. We also focus on the important advances in thin-film electrodes, electrolytes and interfacial layers with the aim of providing insight into the future design of batteries. Furthermore, various thin-film fabrication techniques are also covered in this review.

Graphene with fascinating physicochemical properties has been regarded as one of the most promising candidates to substitute the commercial graphite anode for next-generation lithium-ion batteries (LIBs). [1] As originally suggested by Dahn's group, Li ions can be adsorbed on each side of graphene, forming a Li 2 C 6 stoichiometry with a theoretical specific capacity of 744 mAh g −1 , twice that of graphite (372 mAh g −1 of the first-stage LiC 6 intercalation compound). [2] However, in situ Raman spectroscopy reveals that it is difficult to achieve high Li coverage on graphene because of the low binding energy of Li with carbon and the strong Coulombic repulsion between the adsorbed Li ions. [3] Using density functional theory (DFT) calculations, Lee et al. also found that Li cannot reside on the surface of pristine graphene since its adsorption energy is positive for the entire range of Li content. [4] Therefore, the Li storage capacity of pristine graphene is far from its theoretical value, and is even inferior to that of graphite. Accordingly, it was proposed that defective graphene presents superior Li adsorption because of the increased charge transfer between Li and the defects, and moreover, the specific capacity rises with the increase of defects densities. [5] In the case of the maximum divacancy defect density, the Li storage capacity can reach up to 1675 mAh g −1 . In this regard, reduced graphene oxide (rGO), a form of graphene prepared by a chemical oxidation-exfoliation-reduction process, has been proven to be a potential anode by virtue of its abundant defects and the residual O-containing functional groups. [6] On the other hand, rGO also exhibits the advantages of mass production from the reduction of graphene oxide (GO) with contained costs, which is an essential step for practical applications. [7] As a result, rGO anode is more frequently studied as compared to its pristine graphene counterpart.The groundbreaking work of graphene anodes was reported in 2008 by Honma's group, who demonstrated that the incorporation of carbonaceous materials, i.e., carbon nanotubes (CNTs) and fullerenes (C 60 ), into graphene sheets can efficiently expand the interlayer spacing, thus higher Li storage capacities. [8] Soon Graphene has long been recognized as a potential anode for next-generation lithium-ion batteries (LIBs). The past decade has witnessed the rapid advancement of graphene anodes, and considerable breakthroughs are achieved so far. In this review, the aim is to provide a research roadmap of graphene anodes toward practical LIBs. The Li storage mechanism of graphene is started with and then the approaches to improve its electrochemical performance are comprehensively summarized. First, morphologically engineered graphene anodes with porous, spheric, ribboned, defective and holey structures display improved capacity and rate performance owing to their highly accessible surface area, interconnected diffusion channels, and sufficient active sites. Surface-modified graphene anodes with less aggreg...
