Sodium-ion batteries (SIBs) have attracted significant attention for their potential to replace lithium-ion batteries, owing to the low cost and natural abundance of sodium resources. Alloy-type anode materials like Sn and Sb possess high theoretical capacities, but they suffer from several shortcomings associated with large volume expansion and electrode disintegration during cycling. Herein, we report SnSb nanoalloy-decorated mesoporous 3-dimensional (3D) NiO microspheres that are prepared using a simple, scalable, colloidal chemistry route. The in situ formed SnSb nanoalloy offers enhanced sodiation/ desodiation reversibility and improved electrode kinetics through fast ionic/ electronic transport. Moreover, the mesoporous structure of the NiO microspheres serves as a robust structure-reinforcing matrix that alleviates the huge volume change of the SnSb nanoalloy and prevents particle agglomeration during sodiation/desodiation. Owing to the synergistic effects of nanosizing and nanoconfinement, this unique microsphere architecture, wherein the SnSb nanoalloys are uniformly distributed within the mesoporous 3D NiO matrix, delivers a high reversible capacity of 315 mAh g À1 with significantly improved cycle and rate performances compared with those of bulk SnSb. This facile, synthetic approach and the enhanced sodium-storage performance of our composite microspheres allow for the design and realization of high-capacity alloying-type anodes for SIBs and versatile composite materials for energy storage applications.

Fracture occurred in electrodes of the lithium-ion battery compromises the integrity of the electrode structure and would exert bad influence on the cell performance and cell safety. Mechanisms of the electrode-level fracture and how this fracture would affect the electrochemical performance of the battery are of great importance for comprehending and preventing its occurrence. Fracture occurring at the electrode level is complex, since it may involve fractures in or between different components of the electrode. In this review, three typical types of electrode-level fractures are discussed: the fracture of the active layer, the interfacial delamination, and the fracture of metallic foils (including the current collector and the lithium metal electrode). The crack in the active layer can serve as an effective indicator of degradation of the electrochemical performance. Interfacial delamination usually follows the fracture of the active layer and is detrimental to the cell capacity. Fracture of the current collector impacts cell safety directly. Experimental methods and modeling results of these three types of fractures are concluded. Reasonable explanations on how these electrode-level fractures affect the electrochemical performance are sorted out. Challenges and unsettled issues of investigating these fracture problems are brought up. It is noted that the state-of-the-art studies included in this review mainly focus on experimental observations and theoretical modeling of the typical mechanical damages. However, quantitative investigations on the relationship between the electrochemical performance and the electrode-level fracture are insufficient. To further understand fractures in a multi-scale and multi-physical way, advancing development of the cross discipline between mechanics and electrochemistry is badly needed.

“…Transmission electron microscopy (TEM) has been commonly used to study electrode materials, which typically contain nanoscale features. TEM has been performed to study many aspects of the Cu 6 Sn 5 electrodes in fresh or delithiated forms. − However, TEM observations of lithiated Cu 6 Sn 5 electrodes are limited. A study showed the formation of cracks on the electrode due to volume expansion upon lithiation were healed during delithiation, but there is a lack of publication which investigates the morphology and distribution of each of the phases formed during the lithiation reaction.…”

Intermetallics such as Cu6Sn5, NiSi2, and CuGa2 etc., are promising candidate materials to replace carbon-based lithium-ion battery anodes. However, the lithiation reactions of these anodes often involve the separation of the inactive phases, a slow process that retards the lithiation kinetics and deactivates their role as a stress buffer. This research visualizes the separated Cu in a lithiated Cu6Sn5 anode by advanced transmission electron microscopy techniques. Cu nanospheres of 3–4 nm are found homogeneously distributed in both Li(13+y)Sn5 and Li13Cu6Sn5 phases, suggesting that Cu is transported by long-range diffusion from the reaction site at the Li(13+y)Sn5/Li13Cu6Sn5 phase boundaries.
