“…Thesodium storage performance of these cobalt sulfide TSNBs is comparable to that of many reported cobalt sulfide-based anode materials (Table S1). [8,13,17,18,[41][42][43][44][45][46][47] Thee lectrochemical impedance spectroscopy results reveal that the charge-transfer resistance of the cobalt sulfide TSNBs is smaller than that of the solid particles ( Figure S17, S18). Although the multishelled structure is hard to be observed, the particles still retain their cubic morphology after 100 cycles ( Figure S19).…”

We report the synthesis of cobalt sulfide multishelled nanoboxes through metal-organic framework (MOF)based complex anion conversion and exchange processes.The polyvanadate ions react with cobalt-based zeolitic imidazolate framework-67 (ZIF-67) nanocubes to form ZIF-67/cobalt polyvanadate yolk-shelled particles.T he as-formed yolkshelled particles are gradually converted into cobalt divanadate multi-shelled nanoboxes by solvothermal treatment. The number of shells can be easily controlled from 2t o5by varying the temperature.F inally,c obalt sulfide multi-shelled nanoboxes are produced through ion-exchange with S 2À ions and subsequent annealing. The as-obtained cobalt sulfide multi-shelled nanoboxes exhibit enhanced sodium-storage properties when evaluated as anodes for sodium-ion batteries. Fore xample,ahigh specific capacity of 438 mAh g À1 can be retained after 100 cycles at the current density of 500 mA g À1 .The fast depletion of fossil fuels and growing environmental concerns have prompted intense research efforts for the development of clean and sustainable energy storage and conversion technologies.Electrical energy storage devices as one of the most important components in the development of sustainable energy systems have attracted significant research interest. [1][2][3] Besides lithium-ion batteries (LIBs), sodium-ion batteries (SIBs) have been considered as one promising energy storage alternative because sodium is abundantly available. [2,[4][5][6][7][8] Among the potential negative electrode materials for SIBs,t ransition metal sulfides (TMSs) are quite attractive because of their rich redox sites,high capacity and enhanced electrical conductivity compared with their oxide counterparts. [9][10][11][12][13] However,p ractical applications of TMSs are still hindered by the poor rate performance and fast capacity fading due to the low intrinsic electric conductivity, gradually reduced crystallinity and inevitable volume changes during prolonged cycling.To circumvent these problems,r ational design of the structural complexity of active materials has been proved ap romising strategy. [9,[14][15][16][17][18] In particular,h ollow structures with complex interiors have drawn significant attention owing to their structure-dependent merits.A sf or sodium storage applications,i ntricate hollow structures exhibit great advantages over simple hollow architectures. [16,[19][20][21] Complex hollow particles not only inherit all the advantages of hollow structures,i ncluding high surface area, enhanced volume change accommodation and large electrode/electrolyte interface,b ut also improve the weight fraction of active species,thus dramatically enhancing the energy density of the electrode materials. [22] As ar esult, av ariety of electrode materials have been fabricated in the form of multi-shelled hollow structures. [23][24][25][26][27][28][29][30][31] It is also noted that non-spherical particles might exhibit some advantage for SIBs, [9,15] owing to their larger surface area compared to spherical counterpart...

To achieve a high volumetric capacity, both high tap density and high gravimetric capacity should be considered in one electrode. Herein, microcrystalline graphite (MG), a type of excellent graphite host, is proposed for the large‐scale preparation of FeCl3‐intercalated graphite intercalation compounds (GICs) to simultaneously meet the requirements of high tap density (0.95 g cm−3) and high gravimetric capacity (905 mAh g−1). FeCl3‐intercalated MG achieves the integration of isotropic orientation structure, amorphous carbon ingredients between graphite grains, and crumpled graphite layers, thus effectively buffering structure expansion and suppressing the dissolution of soluble FeCl3 guest and LiCl discharge products. In a lithium‐ion cell, the anode shows a high volumetric capacity of 859 mAh cm−3 and a stable cycle performance for lithium‐ion storage. More importantly, the influence of microstructure features of GICs on their electrochemical properties is demonstrated, which may be of great value to better design and prepare other GIC anodes for high volumetric capacity and good cycle stability.

Sodium-ion batteries (SIBs) have huge potential for applications in large-scale energy storage systems due to their low cost and abundant sources. It is essential to develop new electrode materials for SIBs with high performance in terms of energy density, cycle life, and cost. Metal binary compounds that operate through conversion reactions hold promise as advanced anode materials for sodium storage. This Review highlights the storage mechanisms and advantages of conversion-type anode materials and summarizes their recent development. Although conversion-type anode materials have high theoretical capacities and abundant varieties, they suffer from multiple challenging obstacles to realize commercial applications, such as low reversible capacity, large voltage hysteresis, low initial coulombic efficiency, large volume changes, and low cycling stability. These key challenges are analyzed in this Review, together with emerging strategies to overcome them, including nanostructure and surface engineering, electrolyte optimization, and battery configuration designs. This Review provides pertinent insights into the prospects and challenges for conversion-type anode materials, and will inspire their further study.
