“…Most research activities have been devoted to discovering high‐performance anodes to boost the energy density of Na‐ion batteries (Figure c and Table S1, Supporting Information), because graphite shows much lower storage capability for Na compared to Li . Hard carbon, phosphorus, metal oxides, metal sulfides, and organic compounds exhibit a much higher capacity but low Coulombic efficiency . Furthermore, some of the anode materials suffer from poor electronic conductivity, limited natural abundance, and toxicity, which hinder their practical applications …”

Sodium-based batteries have attracted considerable attention and are recognized as ideal candidates for large-scale and low-cost energy storage. Sodium (Na) metal anodes are considered as one of the most promising anodes for next-generation, high-energy, Na-based batteries owing to their high theoretical specific capacity (1166 mA h g −1 ) and low standard electrode potential. Herein, an overview of the recent developments in Na metal anodes for high-energy batteries is provided. The high reactivity and large volume expansion of Na metal anodes during charge and discharge make the electrode/electrolyte interphase unstable, leading to the formation of Na dendrites, short cycle life, and safety issues. Design strategies to enable the efficient use of Na metal anodes are elucidated, including liquid electrolyte engineering, electrode/electrolyte interface optimization, sophisticated electrode construction, and solid electrolyte engineering. Finally, the remaining challenges and future research directions are identified. It is hoped that this progress report will shape a consistent view of this field and provide inspiration for future research to improve Na metal anodes and enable the development of high-energy sodium batteries.

“…Therefore, it drives the exploring of new materials for high‐performance SIBs. Transitional metal oxide nanomaterials have drawn considerable attention as anode materials for SIBs owing to their distinct reaction mechanism, abundant active sites, and short diffusion pathways . Among them, titanium dioxide (TiO 2 ) has been extensively studied in recent years due to its natural abundance, low cost, environment friendliness, attractive theoretical specific capacity of 335 mA h g −1 , and superior structure's stability during the charge/discharge processes .…”

Herein, 1D free‐standing and binder‐free hierarchically branched TiO2/C nanofibers (denoted as BT/C NFs) based on an in situ fabrication method as an anode for sodium‐ion batteries are reported. The in situ fabrication endows this material with large surface area and strong structural stability, providing this material with abundant active sites and smooth channels for fast ion transportation. As a result, BT/C NFs with the character of free‐standing membranes are directly used as binder‐free anode for sodium‐ion batteries, delivering a capacity of 284 mA h g−1 at a current density of 200 mA g−1 after 1000 cycles. Even at a high current density of 2000 mA g−1, the reversible capacity can still achieve as high as 204 mA h g−1. By means of kinetic analysis, it is demonstrated that the remarkable surface pseudocapacitive behavior is also a major factor to achieve excellent performance. The rationally designed structure coupled with the inherent pseudocapacitive behavior gives this material potential for sodium‐ion batteries.

“…It can be clearly observed that the CDI performance of MnO 2 /f‐AC// f‐AC‐based electrode stands high among various carbon‐based and metal‐oxide‐carbon electrodes while being more cost‐effective since it is biowaste‐derived. Specifically, α‐MnO 2 /f‐AC// f‐AC‐based fabricated electrodes exhibit inverted CDI performance based on the salt ions adsorbed during the discharging process of the principle of sodium ions battery . Figure (d) shows a schematic representation depicting the functioning of α‐MnO 2 /f‐AC// f‐AC‐based fabricated electrodes hybrid CDI device.…”

In this study, the electro‐sorption capacity and selectivity of activated carbon (AC) electrodes, produced from the leaf base of Phoenix dactylifera (palm tree) waste, are modified by enabling the reversible intercalation/conversion of sodium ions through the presence of nanoscale α‐MnO2 particles acting as redox mediators. The α‐MnO2 nanoparticles (NPs) are hydrothermally grown on the AC powder to obtain a functional composite material (α‐MnO2/f‐AC). The morphological, textural, and physicochemical surface properties of the pristine and modified AC materials are thoroughly examined and correlated with the electrochemical performance of the resulting electrodes that are implemented in an asymmetric capacitive deionization (CDI) cell configuration (i. e. capacitive vs Faradaic electrodes). The pristine biowaste‐derived AC presents a high specific surface area of 1224 m2 g−1, and high electrical capacitance of 259 F g−1 at 10 mV s−1. The α‐MnO2 surface modification approach of the pristine material retains its large accessible surface area, and additionally enables a 50% increase in its specific capacitance value. The incorporation of the α‐MnO2/f‐AC material in the anode and the pristine source in the cathode produces superior electrosorption capacity, as high as 17.8mgg−1 in batch‐mode CDI tests with 600mg L−1 NaCl feed. The enhanced electrical performance and pseudocapacitive behavior of the CDI cell can be explained by the α‐MnO2 nanoparticles playing a critical role in enabling a synergistic redox‐based charge‐discharge pathway under conditions compatible with the voltage operation requirements of the CDI process.
