“…Graphene as an anode was widely explored in LIBs, but the same as a potential candidate for cathode was less investigated. The carbon-based electrodes are capable of the formation of oxocarbon salt (Li2C6O6) reversibly enabling the development of new generation sustainable as well as eco-friendly energy storage devices [96][97][98]. In 2013, Sung et al [99] reported the development of reduced graphene oxide which serves as free-standing cathodes for LIBs.…”

In the present era, different allotropes of carbon have been discovered, and graphene is the one among them that has contributed to many breakthroughs in research. It has been considered a promising candidate in the research and academic fields, as well as in industries, over the last decade. It has many properties to be explored, such as an enhanced specific surface area and beneficial thermal and electrical conductivities. Graphene is arranged as a 2D structure by organizing sp2 hybridized C with alternative single and double bonds, providing an extended conjugation combining hexagonal ring structures to form a honeycomb structure. The precious structure and outstanding characteristics are the major reason that modern industry relies heavily on graphene, and it is predominantly applied in electronic devices. Nowadays, lithium-ion batteries (LIBs) foremostly utilize graphene as an anode or a cathode, and are combined with polymers to use them as polymer electrolytes. After three decades of commercialization of the lithium-ion battery, it still leads in consumer electronic society due to its higher energy density, wider operating voltages, low self-discharge, noble high-temperature performance, and fewer maintenance requirements. In this review, we aim to give a brief review of the domination of graphene and its applications in LIBs.

“…The characteristic Raman spectra of graphene/graphite show the following features: (i) the D peak at $1350 cm À1 (due to the breathing modes of the sp 2 hybridized carbon rings); (ii) the G peak at $1580 cm À1 (the E 2g phonon at the Brillouin zone center); (iii) the D 0 peak at $1620 cm À1 (double resonance in an intra-valley process, i.e., connecting two points belonging to the same cone around K or K 0 ); (iv) 2D peak at $2700 cm À1 (second order resonance of the D band); (v) and a combination mode (D + D 0 ) at about 2950 cm À1 (i.e., the combination of D and D 0 bands). 15,16,22,47,48 The incomplete graphene/graphite sample edges act as the point defects. 22 At the center of the pristine graphene akes, the D mode is Raman inactive due to the absence of structural defects; therefore, the I D /I G ratio is zero.…”

“…[12][13][14] Among such applications, graphene is lucrative in electrochemical energy storage. 11,[15][16][17][18][19] In particular, graphene is a superior cathode material for ABs and has a huge potential for commercialization. 3,10,20,21 However, this was primarily limited by the lack of mass production of graphene.…”
