“…The electrochemical performance of various H/Li/Na 4x/3 Ti 2−x/3 O 4 structure anodes of SIBs is summarized and compared in Figur e 3F. 16,18,19,24,26,27,32,33,36,42,71 Our HTO@rGO electrode exhibits better high capacities than that of H 2 Ti 3 O 7 at all current densities. Although the capacities of HTO@rGO are a bit lower than the best NTO or LTO anode at low current densities, HTO@ rGO exhibits high capacities at large current densities, such as 5-10 A g −1 .…”

Insertion type material has been attracted plenty of attentions as the anode of sodium ion batteries (SIBs) due to the low volume change induced long cycle stability. H 1.07 Ti 1.73 O 4 (HTO), a two-dimensional layered material, is a new insertion type anode material for SIBs reported in this study. Layered HTO composites were decorated with rGO nanosheets via an electrostatic assembly method followed by hydrothermal treatment. When adapted as the anode material of SIBs, HTO@rGO composite exhibits an enhanced sodium ion storage behavior, including high rate capability and long cycle stability. It can deliver high capacities of 142.8 and 66.7 mA h g −1 at 100 and 10 000 mA g −1 , respectively. Moreover, it can keep a capacity of 75.1 mA h g −1 at 5 A g −1 after even 5000 cycles, corresponding to a high capacity retention of 70.8% (0.0058% capacity decay per cycle). HTO exhibits a small volume expansion of 19.6% by in-situ transmission electron microscopy (in-situ TEM). The diffusion coefficient of sodium ions is increased from 1.77 × 10 −14 cm 2 s −1 in HTO composites to 4.80 × 10 −14 cm 2 s −1 in HTO@rGO composites. Our designed and synthesized HTO@rGO provides a new route for high rate and long cycle stable SIBs anode materials.

Rechargeable sodium‐ion batteries (SIBs) are emerging as a viable alternative to lithium‐ion battery (LIB) technology, as their raw materials are economical, geographically abundant (unlike lithium), and less toxic. The matured LIB technology contributes significantly to digital civilization, from mobile electronic devices to zero electric‐vehicle emissions. However, with the increasing reliance on renewable energy sources and the anticipated integration of high‐energy‐density batteries into the grid, concerns have arisen regarding the sustainability of lithium due to its limited availability and consequent price escalations. In this context, SIBs have gained attention as a potential energy storage alternative, benefiting from the abundance of sodium and sharing electrochemical characteristics similar to LIBs. Furthermore, high‐entropy chemistry has emerged as a new paradigm, promising to enhance energy density and accelerate advancements in battery technology to meet the growing energy demands. This review uncovers the fundamentals, current progress, and the views on the future of SIB technologies, with a discussion focused on the design of novel materials. The crucial factors, such as morphology, crystal defects, and doping, that can tune electrochemistry, which should inspire young researchers in battery technology to identify and work on challenging research problems, are also reviewed.

“…Electrochemical energy storage technologies have attracted wide attention to utilizing sustainable energy. − Especially, lithium-ion batteries (LIBs) have become the dominating energy storage system with widespread applications. − However, the unevenly distributed and limited lithium resources in the earth’s crust inevitably lead to high costs. In this regard, sodium-ion batteries (SIBs), with the cost-effectiveness of abundant sodium resources, as well as the electrochemical similarity with LIBs, have shown their great potential in terms of large-scale energy storage. − However, SIBs display low specific capacity and sluggish reaction dynamics arising from the higher redox potentials of Na + /Na (−2.7 V) compared with Li + /Li (−3.0 V) and larger atomic radius of Na + (1.02 Å) to Li + (0.76 Å). − Unlike LIBs that can directly use graphite as the anode, suitable anodes for SIBs are still under exploration. Therefore, research into anode materials with outstanding capacity and prolonged lifespan is crucial.…”

A sodium-ion battery, with a wide operating range, is much cheaper and safer than a lithium battery. Graphene is regarded as a promising carbon material in the preparation of anode materials. However, the large two-dimensional (2D) graphene sheets restrain the cross-plane diffusion of electrolyte ions, limiting the further improvement of rate performance. Herein, a nanohybrid of FeCo 2 Se 4 and holey graphene (FeCo 2 Se 4 /HG) has been successfully prepared by the synchronism of pore creation and active material growth. Specifically, FeCo-oxide nanoparticles serve as the etching agents, generating in-plane nanoholes and subsequently converted into FeCo 2 Se 4 . The nanoholes provide a high density of cross-plane diffusion channels for sodium ions, serving as ionic diffusion shortcuts between different graphene layers to accelerate ion transport across the entire electrode. The unique architecture endows FeCo 2 Se 4 /HG with superior rate capability (411.2 mA h g −1 at 20 A g −1 ) and a specific capacity of 432.4 mA h g −1 at 2.0 A g −1 after 2000 cycles with a capacity retention rate of 92.4%. Therefore, pore engineering makes it possible for holey graphene-based electrodes to achieve outstanding rate performance and superb cycling durability.
