“…The hollow structure contributes to the immobilization of sulfur and the strength to accommodate volumetric expansion. [82] As a result, the Li-S battery acquired a capacity of 1053 mAh g −1 at 0.5 C. [76] As reviewed above, metal oxides serving as host materials for sulfur have drawn much attention due to their chemical interaction with LiPSs.…”

Lithium‐sulfur (Li‐S) batteries are one of the most promising next‐generation energy‐storage systems. Nevertheless, the sluggish sulfur redox and shuttle effect in Li‐S batteries are the major obstacles to their commercial application. Previous investigations on adsorption for LiPSs have made great progress but cannot restrain the shuttle effect. Catalysts can enhance the reaction kinetics, and then alleviate the shuttle effect. The synergistic relationship between adsorption and catalysis has become the hotspot for research into suppressing the shuttle effect and improving battery performance. Herein, the adsorption‐catalysis synergy in Li‐S batteries is reviewed, the adsorption‐catalysis designs are divided into four categories: adsorption‐catalysis for LiPSs aggregation, polythionate or thiosulfate generation, and sulfur radical formation, as well as other adsorption‐catalysis. Then advanced strategies, future perspectives, and challenges are proposed to aim at long‐life and high‐efficiency Li‐S batteries.

“…1) Both doping and vacancy can effectively introduce unpaired electrons into the crystal, thus improving material electrical conductivity. [147] 2) Doped ions of different sizes or generation of certain vacancy defects can change crystal cells structure, expand lattice channels, thus enhance ions diffusion coefficient. [148] 3) Doped ions can hinder grain growth, resulting in smaller average particle size than pure.…”

In various energy storage devices, the development and research of electrode materials has always been a key factor. Nb‐based materials are one choice of energy storage materials because of the good ion‐diffusion channels and high theoretical capacity. More importantly, their advantages, such as safe potential range, high structural stability, and highly reversible redox reaction with small strain, are conducive to efficient, safe, and stable energy storage development. Based on aforementioned superiority, much of the research is to further optimize performance of Nb‐based materials by unique nano‐morphology design, lattice regulation, and functional additives composition, showing good electrochemical performance in many kinds of devices. This review mainly introduces the classification of Nb‐based materials used for energy storage, their application in different battery systems, and common optimization methods. Accordingly, the deficiencies and prospects of Nb‐based materials are also discussed in detail.

dimensions of materials are decreased to the nanoscale, the high surface aspect ratio generates additional engineerable space, which enables the polymorphism of nanomaterials. Recently, nano polymorphism (NPM) has been emerging as a topic of interest in the energy storage field, and research is expected to identify and rationally exploit the "processingstructure-properties" relationships of functional materials of interest in the context of the emerging rechargeable battery applications, particularly for cathode and anode materials. To date, the research on the NPM of rechargeable battery electrodes has achieved significant progress. [1-3] Many electrode materials with various polymorphs, such as traditional layered metal oxides and some emerging types of graphene-like nanosized materials, have been intensively investigated for improving the electrochemical performance of batteries. Moreover, the in-depth underlying storage mechanisms of different polymorphs have been fully or partly revealed using advanced in situ characterization techniques. Based on the previously reported theoretical and experimental results, some potential structural Nano polymorphism (NPM), as an emerging research area in the field of energy storage, and rechargeable batteries, have attracted much attention recently. In this review, the recent progress on the composition and formation of polymorphs, and the evolution processes of different redox electrodes in rechargeable metal-ion, metal-air, and metal-sulfur batteries are highlighted. First, NPM and its significance for rechargeable batteries are discussed. Subsequently, the current NPM modulation strategies of different types of representative electrodes for their corresponding rechargeable battery applications are summarized. The goal is to demonstrate how NPM could tune the intrinsic material properties, and hence, improve their electrochemical activities for each battery type. It is expected that the analysis of polymorphism and electrochemical properties of materials could help identify some "processing-structure-properties" relationships for material design and performance enhancement. Lastly, the current research challenges and potential research directions are discussed to offer guidance and perspectives for future research on NPM engineering.
