“…Interestingly, Fe 2 O 3 is regarded as a promising candidate for LIB anode materials because of its high theoretical specific capacity of 1007 mAh g –1 and relatively low voltage platform compared to a large number of transition metal compounds (e.g., Co 3 O 4 , NiO, CuO, etc. ). − Unfortunately, the poor electrical conductivity, notable volume expansion, and aggregation during the charge/discharge process make iron oxide electrodes susceptible to pulverization, resulting in poor rate performance, fast capacity fading, and short cycle life. − Considerable efforts have been made to alleviate the existing issues, especially to reduce Fe 2 O 3 particles from microsized to nanosized, design special morphologies to alleviate the volume expansion (e.g., nanoplates, nanotubes, nanospheres, nanosheets), and also composite with other materials, especially highly electrically conductive carbon materials. , …”

Lithium-ion batteries (LIBs) are the most preferred alternatives to fossil fuels as energy providers, but further improvement of the overall performance is still desired to satisfy social requirements. In this work, ferric oxide nanoparticles encapsulated in biomass longan pulp-derived carbon are simply configurated, in which the longan pulp plays three main functions: (i) To ensure a nanorod-like structure when interacting with Fe 3+ ; (ii) to construct a cubic phase of Fe 2 O 3 by tuning the proper content of longan pulp; and (iii) to ensure good dispersion of Fe 2 O 3 nanoparticles. As electrodes for LIBs, the novel composite shows a high initial discharge capacity of 1483.6 mAh g −1 at 0.1 A g −1 and maintains a capacity value of 626.6 mAh g −1 even at 1.0 A g −1 over 1000 cycles, which benefits from the synergistic effect between carbon nanorods and Fe 2 O 3 . The highly dispersed γ-phase cubic Fe 2 O 3 nanoparticles anchoring on the carbon substrate can increase the contact between the electrolyte and active materials; meanwhile, the longan-derived carbon substrate can compensate for the unfavorable electrical conductivity of Fe 2 O 3 and buffer the volume expansion in the cycling process. This study provides an effective technique to utilize extensive natural resources and simple synthesis procedures for the preparation of novel hybrid anode materials.

“…On the other hand, CNTs are 1D cylinders composed of one or more rolled-up layers of graphene sheets. These structures typically have aspect ratios greater than 1000, allowing them to exhibit extremely rapid electron transport (up to 10 6 S cm −1 ) [133,134,137]. Both carbon structures have been incorporated into composite Ni cathodes as conductive substrates upon which the redox-active materials are grown or deposited.…”

“…While many doping strategies are surficial, Chen et al [133] demonstrated the synergistic effect of surface phosphorylation and bulk phosphorus doping on Fe 2 O 3 nanoporous arrays for LIB applications. Surface doping suppressed surface side reactions and promoted selectivity towards anodic oxidation, while bulk doping enhanced the ion and electron transport and the surface faradaic redox sites.…”

The nickel-iron (Ni-Fe) battery is a century-old technology that fell out of favor compared to modern batteries such as lead–acid and lithium-ion batteries. However, in the last decade, there has been a resurgence of interest because of its robustness and longevity, making it well-suited for niche applications, such as off-grid energy storage systems. Currently, extensive research is focused on addressing perennial issues such as iron passivation and hydrogen evolution reaction, which limit the battery’s energy density, cyclability, and rate performance. Despite efforts to modify electrode composition and morphology, these issues persist, warranting a deeper look at the development story of Ni-Fe battery improvements. In this review, the fundamental reaction mechanisms are comprehensively examined to understand the cause of persisting issues. The design improvements for both the anode and cathode of Ni-Fe batteries are discussed and summarized to identify the promising approach and provide insights on future research directions.

“…Therefore, for addressing this issue, point defect engineering in TiO 2 including the introduction of oxygen vacancies for enhancing the electrical conductivity and kinetics as well as heteroatoms doping modification for improving ion diffusion dynamics and electron transport to promote fast and efficient charge transfer have has been widely studied [16,17]. Among various heteroatom doing processes, phosphorus doping (P-doping), which is to be able to induce an increase in the free charge carriers, promote the electron/ion transfer kinetics and enhance the surface active sites due to the synergistic effect of surface phosphorylation layer and bulk P doping defect, is known to be beneficial for improving electrochemical performances [18,19]. Until now, much effort has been focused on the research of P-doped TiO 2 due to its reduced band gap, which in turn helps to exhibit effective photocatalytic efficiency under visible light exposure and enhance electrode's electrical conductivity and charge carrier [20,21].…”

Limited by the intrinsic low electronic conductivity and inferior electrode kinetics, the use of TiO2 as an anode material for lithium ion batteries (LIBs) is hampered. Nanoscale surface-engineering strategies of morphology control and particle size reduction have been devoted to increase the lithium storage performances. It is found that the ultrafine nanocrystal with mesoporous framework plays a crucial role in achieving the excellent electrochemical performances due to the surface area effect. Herein, a promising anode material for LIBs consisting of phosphorus-doped TiO2 mesoporous nanocrystals (P-TMC) with ultrafine size of 2-8 nm and high specific surface area of 234.164 m2 g─1 has been synthesized. It is formed through a hydrothermal process and NaBH4 assisted heat treatment for anatase defective TiO2 (TiO2-x) formation followed by a simple gas phosphorylation process in a low-cost reactor for P-doping. Due to the merits of the large speciﬁc surface area for providing more reaction sites for Li+ ions to increase the storage capacity and the presence of oxygen vacancies and P-doping for enhancing material’s electronic conductivity and diffusion coefﬁcient of ions, the as-designed P-TMC can display improved electrochemical properties. As a LIB anode, it can deliver a high reversible discharge capacity of 187 mAh g─1 at 0.2 C and a good long cycling performance with ~82.6 % capacity retention (101 mAh g─1) after 2500 cycles at 10 C with an average capacity loss of only 0.007% per cycle. Impressively, even the current rate increases to 100 times of the original rate, a satisfactory capacity of 104 mAh g−1 can be delivered, displaying good rate capacity. These results suggest the P-TMC a viable choice for application as an anode material in LIB applications. Also, the strategy in this work can be easily extended to the design of other high-performance electrode materials with P-doping for energy storage.
