Nanostructured Graphene Oxide-Based Hybrids as Anodes for Lithium-Ion Batteries

Abstract

Presently, the negative electrodes of lithium-ion batteries (LIBs) are constituted by carbon-based materials, which exhibit a limited specific capacity 372 mAh g−1 associated with the cycle in the composition between C and LiC6. Therefore, many efforts are currently made towards the technological development of nanostructured graphene materials because of their extraordinary mechanical, electrical, and electrochemical properties. Recent progress on advanced hybrids based on graphene oxide (GO) and reduced graphene oxide (rGO) has demonstrated the synergistic effects between graphene and an electroactive material (silicon, germanium, metal oxides (MOx)) as electrode for electrochemical devices. In this review, attention is focused on advanced materials based on GO and rGO and their composites used as anode materials for lithium-ion batteries.

Controlled nanostructure of a graphene nanosheet‐TiO 2 composite fabricated via mediation of organic ligands for high‐performance Li storage applications

“…The L‐GNS‐TiO 2 composite delivers reversible Li storage capacities of 173 and 330.6 mAh g −1 during the first cycle and after 450 cycles, respectively, at 0.15 A g −1 . The considerable increase in capacity can be attributed to an activation process of TiO 2 , which has been typically observed in metal sulfide or oxide‐based LIB anode materials 27,58‐61 . Moreover, the activation process of the electrode can be induced by the formation of a reversible polymeric gel‐like film upon the degradation of the activated electrolyte at a low potential through a so‐called “pseudo‐capacitance‐type behavior” due to the catalytic activity of the TiO 2 nanoparticles 23,26,59‐63 …”

“…Also, the aqueous 0.5 M Zn (CF 3 SO 3 ) 2 electrolyte supports better cycling stability by decreasing the water molecules surrounding Zn 2+ ions, thus improving charge transfer. [45][46][47] In Fig. 6, the series combination of the individual cell produces 12 V energy.…”

A Comprehensive Review of Current and Emerging Binder Technologies for Energy Storage Applications

“…The oxygen-containing functional groups on GO's surface can act as an effective barrier against the permeation of electrolyte solvents, preventing their unwanted reactions with the electrode materials. This characteristic can significantly improve the cycling stability and safety of batteries, particularly in high-energy applications 56 . 57 Furthermore, the unique 2D structure of GO provides a large surface area for active material anchoring and facilitates efficient charge transfer during battery operation.…”

“…Graphene oxide and its related compounds are emerging as promising binder materials for sodium-ion batteries and lithium–sulfur batteries. ,, Hao et al have suggested that free-standing rGO/CNT paper demonstrates capacitive charge storage, enhancing sodium ion storage and ensuring stable cyclability. This flexible rGO/CNT paper, proposed as a potential anode candidate for sodium-ion batteries, showcases an exceptional rate performance, maintaining a specific capacity of 101.4 mAh g –1 at a current rate density of 0.1 A g –1 , even under a demanding cycling rate of 5 A g –1 (refer to Figure ).…”
