Transition metal carbides and/or nitrides (MXenes), a burgeoning group of 2 D layer‐structure compounds, have multiple merits, such as high electrical conductivity, tunable layer structure, small band gap, and functionalized redox‐active surface, and are receiving significant attention as one of the most promising class of energy storage materials. The synthesis methods, structural configuration, and surface chemistry of MXenes directly influence their performance. This Minireview focuses on interfacial structure design and functionalization of MXenes and MXene‐based energy storage materials and the effect of structural configuration and surface chemistry on their electrochemical performance. Additionally, the structure–property relationships between interfacial structure, functional group, interlayer spacing, and the corresponding energy storage performance are summarized in detail. Finally, light is shed on the perspectives for the future research on advanced MXene‐based energy storage materials including scientific and technical challenges.

“…[41] However, with the rapid growth of electronic vehicles (EVs) and smart power grids, the state-of-the-art cathode materials used in LIBs (e. g., layered metal oxides and spinel structures) based on the insertion/desertion chemistry are far from practical applications in these areas due to their insufficient energy density and high cost. [42] Therefore, exploring rechargeable batteries based on different reaction mechanisms is a promising direction. [43] Sulfur, as a cathode material, could directly react with lithium through two-electron redox process, yielding a high specific capacity (1675 mA h g À 1 ) and energy density (2600 Wh kg À 1 ), which is much higher than the current LIBs (Figure 7).…”

Carbon is a simple, stable and popular element with many allotropes. The carbon family members include carbon dots, carbon nanotubes, carbon fibers, graphene, graphite, graphdiyne and hard carbon, etc. They can be divided into different dimensions, and their structures can be open and porous. Moreover, it is very interesting to dope them with other elements (metal or non‐metal) or hybridize them with other materials to form composites. The elemental and structural characteristics offer us to explore their applications in energy, environment, bioscience, medicine, electronics and others. Among them, energy storage and conversion are extremely attractive, as advances in this area may improve our life quality and environment. Some energy devices will be included herein, such as lithium‐ion batteries, lithium sulfur batteries, sodium‐ion batteries, potassium‐ion batteries, dual ion batteries, electrochemical capacitors, and others. Additionally, carbon‐based electrocatalysts are also studied in hydrogen evolution reaction and carbon dioxide reduction reaction. However, there are still many challenges in the design and preparation of electrode and electrocatalytic materials. The research related to carbon materials for energy storage and conversion is extremely active, and this has motivated us to contribute with a roadmap on ‘Carbon Materials in Energy Storage and Conversion’.

However, the volumetric density of the electrodes is always ignored during the pursuit of high performance active materials.…”

Submicrospherical and Porous Bi₂S₃ Protected by Nitrogen‐Doped Carbon for Practical Anode Fabrication of Li‐Ion Batteries

Research on alloy‐type anode materials with micro/submicrospherical morphology is of great significance for the development of high energy‐density Li‐ion batteries. A facile and cost‐effective route is adopted to prepare homogeneous submicrospherical and porous Bi2S3@nitrogen‐doped carbon (NC) nanocomposites, which exhibit considerably better Li‐storage performance than pure Bi2S3 and Bi2O3 submicrospheres. Analyses on the electrochemical behavior and morphology of the electrode show that the good performance of Bi2S3@NC can be correlated with its stable submicrospherical structure and decreased charge‐transfer resistance, for which the NC coating layer and porous interior of Bi2S3 are supposed to be the two main contributors. The submicrospherical structure and facile synthesis of Bi2S3@NC will be very suitable for practical electrode fabrication technology of Li‐ion batteries.
