“…[11,12] Unfortunately, only Zn-MnO 2 /V 2 O 5 , Zn-Prussian blue, and Zn-PANi systems can play an important role in ZIBs with organic electrolytes, and both the discharge voltage and capacity are significantly lower than the level of the aqueous electrolyte systems. [13][14][15][16][17][18] Therefore, finding high-stability and high-energy-density cathode materials that work efficiently in both organic and aqueous electrolytes is a key endeavor. Selenium (Se), which can undergo a conversion mechanism in ZIBs, could help achieve the desired battery performance.…”

“…This phenomenon is commonly observed in Li/Na-Se batteries and can sharply reduce the capacity of Zn-Se batteries. [16,[22][23][24] Furthermore, the weak ion and electron transport properties of Se cause the inferior electrochemical performance of Zn-Se batteries. [25,26] Confining Se to various carbon materials with high electronic conductivity has been made to solve the low conductivity of Se; for instance, hierarchically porous carbon, carbon nanofibers, graphene, and multiwalled carbon nanotubes.…”

Zinc–selenium (Zn–Se) batteries have generated great research interest because they could potentially meet the requirements of a high‐capacity, high energy density storage device. Unfortunately, efforts to control the shuttle effect of polyselenides have yielded limited success. Nanostructured carbon hosts with nonpolar surfaces have insufficient ability to restrict polyselenides within the cathode. Herein, first‐principles calculations are used to successfully study the merits of heteroatom‐doped graphene as an efficient sorbent with an excellent ability to inhibit the shuttle effect of polyselenides. The calculation results show that using B as a dopant could distinctly enhance interaction between hosts and polyselenides, which occur significant charge transfer with polyselenides and reduce the diffusion energy barrier of Zn ions. Then, we synthesized carbon/Se and boron‐doped carbon material/Se composite cathodes proving that B‐doped carbon could restrict the shuttle effect of polyselenides, which increases the electrochemical performance of Zn–Se batteries. Therefore, the theoretical study identifies a delightful restricted material that could potentially restrict the shuttle effect in Zn–Se batteries and provides a foundation and strategy for the fabrication of long‐life, high‐power‐density Zn–Se batteries.

“…[8] Several different categories of compounds have been investigated as potential cathode materials. These include layered oxides, [9][10][11][12] polyanionic compounds, [13][14][15][16] Prussian blue analogs, [17,18] and some organics. [19,20] Among them, layered transition-metal (TM) oxides Na x TMO 2 (TM, TM ═ Fe, Mn, Ni, Co, Cr, Ti, V, Cu, and their combinations, 0 < x ≤ 1, the most common structures of Na x TMO 2 are P2, P3, and O3) have been extensively exploited due to their high capacities, good stability, and simple synthesis procedures, and are thus extensively being exploited.…”

Renewable energies, such as solar and wind, have been explored and widely applied for alleviating problems associated with the depletion of fossil fuel resources and environmental pollution. The intermittent and fluctuating features of these renewable energies require development of efficient energy storage and conversion systems. Sodium‐ion batteries (SIBs) are considered one of the most promising candidates for large‐scale energy storage due to the low cost and earth abundance of sodium resources. A major challenge for the practical application of SIBs is the development of appropriate cathodes with high energy densities and cycling stabilities. Layered oxide cathodes have received significant attention because of their relatively simple synthetic routes and high capacities stemming from their layered structures. However, they often suffer from moisture sensitivity and structural degradation upon repeated Na+ insertion/extraction, leading to severe performance fading. This review summarizes and discusses the degradation mechanisms of these layered oxide cathodes and modulation strategies for addressing the stability issues. Understanding the mechanisms behind structural instability would provide better insight for improving SIBs' cathode materials, which has critical implications for the designs and applications of SIBs as renewable energy systems.

“…Sodium batteries have been regarded as a promising nextgeneration technology for large-scale energy storage applications and have attracted enormous attention in recent years because of the low cost and high abundance of sodium resources. [1][2][3][4][5] The reported sodium batteries are mainly based on liquid electrolytes with ammable organic solvents, such as esters and ethers, which inevitably bring about leakage, volatilization, and subsequent safety issues. 6,7 In contrast, all-solidstate electrolytes show the advantages of no leakage, good stability, and high safety.…”
