Perspective to the Potential Use of Graphene in Li‐Ion Battery and Supercapacitor

Abstract

Graphene is a hot star in materials science with various potential application aspects, including in Li‐ion battery and supercapacitor. The burst of scientific papers in this area seems to validate the performance of graphene, but also arouses large dispute. Herein, we share our judgment of these trends to all, encouraging the discussion and enhancing the understanding of the structure‐performance relationship of graphene.

Corn‐based Electrochemical Energy Storage Devices

“…[29] Numerous investigations have been performed to modify these four parts to enhance the electrochemical performance of the EES devices. Tremendous efforts have been accomplished to enhance the electrochemical performance of the EES devices via inorganic materials, [30][31][32][33][34][35][36][37][38] organic materials, [39][40][41][42] organic-inorganic hybrid materials [43][44][45] and renewable biomass materials. [46][47][48][49] All main parts of the EES devices can be prepared by renewable biomass materials.…”

Plasma-Introduced Oxygen Defects Confined in Li4Ti5O12 Nanosheets for Boosting Lithium-Ion Diffusion

“…Therefore, it is significant to develop other alternative anodes. [3][4][5][6][7] The spinel Li4Ti5O12 (LTO) has attracted wide attention as a potential intercalation-type anode candidate with long cycling stability and high safety. The preeminent performance is ascribed by a negligible volume change (often called as 'zero-strain') during the Li-ion insertion/extraction accompanied with one-electron transfer of Ti 4+ and Ti 3+ redox.…”

“…In general, the lithium storage ability strongly depends on the properties of electrode materials, and thus corresponding studies, especially of anode materials, have stood out as the research core recently. , Carbon-based materials have been widely used for commercial anodes, but they suffer from large volume expansion and shrinkage during Li-ion intercalation/extraction and safety concerns owing to lithium dendrite formation at low Li-ion intercalation potential. Therefore, it is significant to develop other alternative anodes. − …”

Self-Assembled Magnetic Nanoparticle–Graphene Oxide Nanotag for Optomagnetic Detection of DNA

“…2−4 To date, graphene and its derivatives have been decorated with different varieties of metal and metal oxide nanoparticles to further enhance their properties and broaden their applications. 5,6 Due to the novel catalytic, optoelectronic, and magnetic properties endowed by the decorated metal and metal oxide nanoparticles, these graphene-based nanocomposites have been used as, e.g., catalysts, 7 supercapacitors, 8 electrode materials, 9 drug carriers, 10 and substrates or transducers of sensors/biosensors. 11−13 Among these different nanoparticle−graphene nanocomposites, magnetic nanoparticle (MNP) decorated graphene/GO nanocomposites have been synthesized by several groups for sensing/biosensing.…”

“…Owing to the exceptional characteristics such as high surface-to-volume ratio and unique mechanical/thermal/electrical properties, graphene and its derivatives have attracted much attention over the past 15 years . Among different derivatives of graphene, graphene oxide (GO), obtained by oxidation of graphite, shows great potential in biomedical applications due to its good water dispersibility and biocompatibility. − To date, graphene and its derivatives have been decorated with different varieties of metal and metal oxide nanoparticles to further enhance their properties and broaden their applications. , Due to the novel catalytic, optoelectronic, and magnetic properties endowed by the decorated metal and metal oxide nanoparticles, these graphene-based nanocomposites have been used as, e.g., catalysts, supercapacitors, electrode materials, drug carriers, and substrates or transducers of sensors/biosensors. − …”
