Silicon has the potential to revolutionize the energy storage capacities of lithium-ion batteries to meet the ever increasing power demands of next generation technologies. To avoid the operational stability problems of silicon-based anodes, we propose synergistic physicochemical alteration of electrode structures during their design. This capitalizes on covalent interaction of Si nanoparticles with sulfur-doped graphene and with cyclized polyacrylonitrile to provide a robust nanoarchitecture. This hierarchical structure stabilized the solid electrolyte interphase leading to superior reversible capacity of over 1,000 mAh g−1 for 2,275 cycles at 2 A g−1. Furthermore, the nanoarchitectured design lowered the contact of the electrolyte to the electrode leading to not only high coulombic efficiency of 99.9% but also maintaining high stability even with high electrode loading associated with 3.4 mAh cm−2. The excellent performance combined with the simplistic, scalable and non-hazardous approach render the process as a very promising candidate for Li-ion battery technology.

Graphene‐containing nanomaterials have emerged as important candidates for electrode materials in lithium‐ion batteries (LIBs) due to their unique physical properties. In this review, a brief introduction to recent developments in graphene‐containing nanocomposite electrodes and their derivatives is provided. Subsequently, synthetic routes to nanoparticle/graphene composites and their electrochemical performance in LIBs are highlighted, and the current state‐of‐the‐art and most recent advances in the area of graphene‐containing nanocomposite electrode materials are summarized. The limitations of graphene‐containing materials for energy storage applications are also discussed, with an emphasis on anode and cathode materials. Potential research directions for the future development of graphene‐containing nanocomposites are also presented, with an emphasis placed on practicality and scale‐up considerations for taking such materials from benchtop curiosities to commercial products.

“…The resulting sample of graphene oxide was reduced by hydrogen at 1000°C. Next, according to research work [63], tetrachlorosilane was introduced by injection, as result of which on the surface of the reduced graphene oxide flakes were formed silicon nanoparticles with a size of 5 to 10 nm. Authors have achieved the MDC equal 1103 mA•h•g −1 for 1000 cycles at 14C charge current, discharge current was 2C, also they have reproduced achieved capacity characteristics of the anode in the model assembly of LIB, where LiCoO 2 was used as a cathode.…”

Abstract. Despite modern technological advances, the creation of powerful, energy-intensive and environmentally friendly energy storage devices is an actual problem. Lithium-ion batteries (LIBs), which have a high density of stored energy and low self-discharge, are the priority in the list of advanced energy storage devices. Performance of LIB depends on the composition and structure of the materials used to create the cathodes and anodes. Recently, among the new materials focusing on graphene combines a number of unique properties of the defining prospects use as electrode materials. This review summarizes the modern main achievements of the period from 2013 by 2015 in the area of graphene application and composite materials on its basis, as materials for the LIB electrodes.
