“…A power-law (i = av b ) can be used to describe the relationship between the peak current (i) and scan rate (v), where a and b are defined as adjustable parameters (He et al, 2014;Liu et al, 2021). In principle, a b value of 0.5 means that the current is controlled by semi-infinite diffusion, while 1.0 indicates a surface capacitive-controlled behavior (Wang et al, 2019;Fu et al, 2020). By fitting the profiles of log(i) as a function of log(v) (Figure 4D), the calculated b values of 0.71 and 0.51 computed for the cathodic and anodic peaks, respectively, indicating that the charge storage of the hierarchical WO 3 agglomerates is mainly dominated by the joint effect of diffusion and capacitivecontrolled processes (Hwang et al, 2019;Liang et al, 2021b).…”

The pursuit of electrochemical energy storage has led to a pressing need on materials with high capacities and energy densities; however, further progress is plagued by the restrictive capacity (372 mAh g−1) of conventional graphite materials. Tungsten trioxide (WO3)-based anodes feature high theoretical capacity (693 mAh g−1), suitable potential, and affordable cost, arousing ever-increasing attention and intense efforts. Nonetheless, developing high-performance WO3 electrodes that accommodate lithium ions remains a daunting challenge on account of sluggish kinetics characteristics and large volume strain. Herein, the well-designed hierarchical WO3 agglomerates assembled with straight and parallel aligned nanoribbons are fabricated and evaluated as an anode of lithium-ion batteries (LIBs), which exhibits an ultra-high capacity and excellent rate capability. At a current density of 1,000 mA g−1, a reversible capacity as high as 522.7 mAh g−1 can be maintained after 800 cycles, corresponding to a high capacity retention of ∼80%, demonstrating an exceptional long-durability cyclic performance. Furthermore, the mechanistic studies on the lithium storage processes of WO3 are probed, providing a foundation for further optimizations and rational designs. These results indicate that the well-designed hierarchical WO3 agglomerates display great potential for applications in the field of high-performance LIBs.

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.

“…[28] The analysis results ascribe that ms-Bi 2 O 3 /CMTs possess a larger specific surface area (156.24 m 2 g À 1 ), average pore volume (0.15 cm 3 g À 1 ) and pore diameter (4.34 nm), which furnishes more active sites for lithium storage, facilitates the insertion and rapid diffusion of Li + , and elevates full wetting of catalytic active sites, thereby promoting conversion kinetics of solid-liquid multi-lithium compounds. [29] The higher surface area and pore volume of ms-Bi 2 O 3 /CMTs are chiefly ascribed to microtube-like carbon matrix and highly dispersed multi-size Bi 2 O 3 nanoparticles exposing more specific surface areas.…”

Multi-size Bi 2 O 3 nanoparticles supported by 1-dimensional (1D) porous carbon microtubes (ms-Bi 2 O 3 /CMTs) were favorably constructed through surface-ion release and in-situ oxidation strategy. The prominent 1D porous microtube materials with multi-size nanoparticles structure can furnish more plentiful electrochemical active sites and shorten lithium storage paths for high-speed redox reactions, which was conducive to ion transport kinetics. The CV tests with various scan rates verified lithium storage mechanism of ms-Bi 2 O 3 /CMTs with diffusion/ capacitance control coexistence. The complexes illustrated an ultra-long cycle life and extraordinary reversible capacity: it still had a specific capacity of 392.6 mAh g À 1 after 3000 cycles at 1 A g À 1 ; and it manifested 546.3 mAh g À 1 when it returned to 0.05 A g À 1 and continued to 100 cycles after experiencing different current densities of 0.05-5 A g À 1 , which indicated that ms-Bi 2 O 3 /CMTs is a prospective anode for lithium-ion batteries (LIBs).
