Review on recent progress of nanostructured anode materials for Li-ion batteries

There are growing concerns over the environmental, climate, and health impacts caused by using non-renewable fossil fuels. The utilization of green energy, including solar and wind power, is believed to be one of the most promising alternatives to support more sustainable economic growth. In this regard, lithium-ion batteries (LIBs) can play a critically important role. To further increase the energy and power densities of LIBs, silicon anodes have been intensively explored due to their high capacity, low operation potential, environmental friendliness, and high abundance. The main challenges for the practical implementation of silicon anodes, however, are the huge volume variation during lithiation and delithiation processes and the unstable solid-electrolyte interphase (SEI) films. Recently, significant breakthroughs have been achieved utilizing advanced nanotechnologies in terms of increasing cycle life and enhancing charging rate performance due partially to the excellent mechanical properties of nanomaterials, high surface area, and fast lithium and electron transportation. Here, the most recent advance in the applications of 0D (nanoparticles), 1D (nanowires and nanotubes), and 2D (thin film) silicon nanomaterials in LIBs are summarized. The synthetic routes and electrochemical performance of these Si nanomaterials, and the underlying reaction mechanisms are systematically described.

Silicon based lithium-ion battery anodes: A chronicle perspective review

The development of new electrode materials for lithium-ion batteries (LIBs) has always been a focal area of materials science, as the current technology may not be able to meet the high energy demands for electronic devices with better performance. Among all the metal oxides, tin dioxide (SnO₂) is regarded as a promising candidate to serve as the anode material for LIBs due to its high theoretical capacity. Here, a thorough survey is provided of the synthesis of SnO₂-based nanomaterials with various structures and chemical compositions, and their application as negative electrodes for LIBs. It covers SnO₂ with different morphologies ranging from 1D nanorods/nanowires/nanotubes, to 2D nanosheets, to 3D hollow nanostructures. Nanocomposites consisting of SnO₂ and different carbonaceous supports, e.g., amorphous carbon, carbon nanotubes, graphene, are also investigated. The use of Sn-based nanomaterials as the anode material for LIBs will be briefly discussed as well. The aim of this review is to provide an in-depth and rational understanding such that the electrochemical properties of SnO₂-based anodes can be effectively enhanced by making proper nanostructures with optimized chemical composition. By focusing on SnO₂, the hope is that such concepts and strategies can be extended to other potential metal oxides, such as titanium dioxide or iron oxides, thus shedding some light on the future development of high-performance metal-oxide based negative electrodes for LIBs.

SnO2‐Based Nanomaterials: Synthesis and Application in Lithium‐Ion Batteries

The ever-increasing demands for energy and environmental concerns due to burning fossil fuels are the key drivers of today's R&D of innovative energy storage systems. This paper provides an overview of recent research progress in graphene-based materials as electrodes for electrochemical energy storage. Beginning with a brief description of the important properties of single-layer graphene, methods for the preparation of graphene and its derivatives (graphene oxide and reduced graphene oxide) are summarized. Then, graphene-based electrode materials for electrochemical capacitors and lithium-ion batteries are reviewed. The use of graphene for improving the performance of lithium–sulfur and lithium–oxygen batteries is also presented. Future research trend in the development of high-power-density and high-energy-density electrochemical energy storage devices is analysed.

Silicon nanotube anode for lithium-ion batteries

A facile method has been developed to synthesize Sn-based nanoparticle-decorated graphene through simultaneous growth of SnO2 nanoparticles and a carbonaceous polymer film on graphene oxide sheets followed by heat treatment at various temperatures (250, 550, 750, and 900 °C). Detailed characterization of the resulting composite material using transmission electron microscopy and field emission scanning electron microscopy suggests that Sn-based nanoparticles were reliably bound to the graphene surface through a carbon film. Cyclic voltammograms and galvanostatic technique were used to investigate electrochemical properties of the Sn-based composite material as the anode of lithium-ion batteries (LIBs). Samples obtained with 550 °C heat treatment, which contained mixed Sn-based components (Sn, SnO, SnO2), exhibit the best electrochemical performance among the series of nanocomposites in terms of specific capacity and cycling stability.

A new graphene-based hybrid nanostructure is designed for anode materials in lithium-ion batteries. The highly branched graphene nanosheets (HBGNs) directly grown on a copper current collector exhibited promising electrochemical performance due to their unique morphology, high electrical conductivity, large interfacial surface area, and high porosity.
