“…A widely used transition metal oxide is iron oxide (Fe 2 O 3 ), considering the low cost and abundant reserves. In order to improve its performance, several approaches have been taken, including in situ encapsulation of α-Fe 2 O 3 nanoparticles into micro-sized ZnFe 2 O 4 capsules [107], a new synthesis method based on chemical precipitation with the sulfuric acid leaching liquor of tin ore tailings as an Fe source [108] and a new material based on Rosa roxburghii-like hierarchical hollow sandwich-structure C@Fe 2 O 3 @C microspheres [109]. In addition, Co 3 O 4 /Co in situ nanocomposites were synthetized to improve SEI [110].…”

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.

“…), many of which showed relatively high capacity. Nevertheless, the electrochemical performance under high current density is not satisfactory, especially the anode materials with long-cycling stability are rarely reported so far. − The reasons are mainly ascribed to the intrinsically sluggish solid-state lithium diffusion and hardly controlling uniform dispersion and aggregation of α-Fe 2 O 3 nanoparticles on graphene or carbon nanotubes during the hydrothermal process. In this sense, most doped graphene and carbon nanotubes cannot effectively mitigate the volume change brought by Li + -ion insertion/extraction .…”

“…As known to all, pseudocapacitance behavior signifies a kind of ultrafast electrochemical reaction derived from the surface-induced capacitive process, which could effectively improve the rate capacity and long-cycling stability through continuous and fast reversible faradic charge-transfer reactions.

Biomass carbon-coated and pseudocapacitance-assisted α-Fe2O3 has recently gained more attention for enhanced lithium storage performance. Herein, we used a waste poplar branch as a biotemplate and a carbon source to prepare graphitic-C-doped mesoporous α-Fe2O3 (α-Fe2O3/C) through a simple immersion–carbonization–calcination method. The influence of carbon content on both the microstructures and electrochemical properties was also studied. The product calcined in air at 400 °C (Fe2O3/C400) presents a hierarchically tubular structure with cross-linkage of 18% graphitic-C and α-Fe2O3 nanoparticles with an average size of ∼28 nm. Meanwhile, the Fe2O3/C400 nanomaterial exhibits a large surface area of 114 m2 g–1 and mesopore size distribution centered at 2 nm. As lithium-ion battery anode material, such a unique hierarchical structure presents a certain pseudocapacitance behavior, thus improving its lithium storage performance. Electrochemical measurements show that the Fe2O3/C400 nanomaterial exhibits higher specific capacity and better rate performance. Especially, it can retain a capacity of 885 mA h g–1 at 1 A g–1 after cycling 1400 times, indicating good capacity retention and long-cycling stability. The good electrochemical performance mainly originates from the synergism of the unique microstructure of the Fe2O3/C400 nanomaterial, suitable doping of graphitic-C, and certain pseudocapacitance behavior. Thus, the low-cost bifunctional biotemplate strategy can provide a useful experience for the massive synthesis of pseudocapacitance-assisted high-performance anodes.

“…In previous studies [10][11][12][13][14], Fe 2 O 3 anode delivered a high specific capacity of 1007 mAh g −1 ; however, volume expansion happening during the process of charge and discharge causes pulverization and failure of contact with the current collector. In this regard, extensive efforts have been devoted to design varieties of nanostructured composites to alleviate the volume expansion, such as 0-3D nanoparticles, nanowires, nanorods, and nanoboxes [15][16][17][18][19]. The nanomodification of the materials and reduction of grain size are beneficial to improve the specific surface area (SSA), increase the active sites, and shorten the diffusion distance of ionic electrons [20], while the composite of C-based materials can effectively buffer the volume change of the material during cycling [21].…”

Transition metal oxides (TMOs) are considered as promising anode materials for lithium-ion batteries in comparison with conventional graphite anode. However, TMO anodes suffer severe volume expansion during charge/discharge process. In this respect, a porous Fe2O3 nanorod-decorated hollow carbon nanofiber (HNF) anode is designed via a combined electrospinning and hydrothermal method followed by proper annealing. FeOOH/PAN was prepared as precursors and sacrificial templates, and porous hollow Fe2O3@carbon nanofiber (HNF-450) composite is formed at 450 °C in air. As anode materials for lithium-ion batteries, HNF-450 exhibits outstanding rate performance and cycling stability with a reversible discharge capacity of 1398 mAh g−1 after 100 cycles at a current density of 100 mA g−1. Specific capacities 1682, 1515, 1293, 987, and 687 mAh g−1 of HNF-450 are achieved at multiple current densities of 200, 300, 500, 1000, and 2000 mA g−1, respectively. When coupled with commercial LiCoO2 cathode, the full cell delivered an outstanding initial charge/discharge capacity of 614/437 mAh g−1 and stability at different current densities. The improved electrochemical performance is mainly attributed to the free space provided by the unique porous hollow structure, which effectively alleviates the volume expansion and facilitates the exposure of more active sites during the lithiation/delithiation process. Graphical abstract Porous Fe2O3 nanorod-decorated hollow carbon nanofibers exhibit outstanding rate performance and cycling stability with a high reversible discharge capacity.
