“…Nanostructured Si and Sn based alloys made by mechanical milling are under intensive study for application in Li-ion batteries, since they can store considerably more Li than conventional graphite negative electrodes. 1,2 During the mechanical alloying process, there is general agreement that the crystallite size of alloys decreases with milling time. 3,4 The final grain size is achieved when there is a balance between dislocation accumulation and dynamic recovery or recrystallization.…”

“…The microstructure of these alloys is critical to their electrochemical performance. 1,2,9,15 The existence of crystalline species will induce 2-phase coexistence during lithiation, resulting in immense stress along phase boundaries, crack propagation, electrical disconnection of alloy particles and, ultimately, severe capacity fade during charge/discharge cycling. 1,2 The electrochemical properties of such alloys are extremely sensitive to their microstructure and can be more sensitive than what is detectable by x-ray diffraction.…”

A rapid method for preparing amorphous alloys has been developed utilizing a SPEX high energy ball mill. Parameters such as ball size, mass of balls and milling time, were systematically optimized to prepare amorphous alloys quickly. Amorphous alloys previously not thought possible to synthesize by means of SPEX milling were made amorphous by the new method. When applied to the preparation of Sn-Co-C and Si-Fe alloys, the method was found to produce fully amorphous alloys in a matter of hours instead of days or weeks of milling by traditional techniques. Electrochemical performance of the alloys produced by the rapid milling technique in Li cells was found to be the same or superior to alloys produced by the more time consuming methods, confirming their amorphous microstructure.

Compared with conventional lithium ion batteries (LIBs), lithium sulfur (Li-S) batteries possess advantages such as higher theoretical energy densities and better cost efficiencies, making them promising next-generation energy storage systems. However, the commercialization of Li-S batteries is impeded by several drawbacks, including low cycling stabilities, limited sulfur utilizations, existing shuttle effects of polysulfide intermediates, serious safety concerns, as well as inferior cycling performances of lithium metal anodes. To address these issues, researchers have achieved rapid developments for sulfur cathodes and increased their attention to lithium metal anodes to facilitate the widespread application of Li-S batteries. And among the substrate materials for electrodes in Li-S batteries being developed, carbon-based materials have been especially promising because of their multifunctionality, demonstrating great potential for application in advanced energy storage and conversion systems. In this review, recent advancements of carbon-based frameworks applied to Li-S batteries will be summarized and diverse utilization methods of these carbon-based materials for both sulfur cathodes and lithium metal anodes will be provided. Future research directions and the prospects of Li-S batteries with high performance and practicability will also be discussed. Keywords

“…The current review aims to highlight the fundamental battery chemistries of the metal anodes and the recent progresses on the modification strategies including nanosizing, composite design, and alloy/intermetallic construction for better performances. [47,48] These strategies are all bene ficial to alleviating the mechanical stress of the metal anodes during battery reactions, thus stabilizing the anode structure, finally contributing to prolonged cycling life as well as enhanced reversibility and high Coulombic efficiency (CE). In addition, investigations on several new battery systems based on metal anodes including dual-ion batteries (DIBs, both anions and cations based battery reactions), aluminum-ion batteries (AIBs, Al 3+ based battery reactions), sodium-ion batteries (SIBs, Na + based battery reactions), magnesium-ion batteries (MIBs, Mg 2+ based battery reactions), and zinc-ion batteries (ZIBs, Zn 2+ based battery reactions) with potential virtues of low cost, high safety and high energy density are also discussed in this review.…”

density. Therefore, developing highcapacity anode and cathode materials or new battery systems have drawn extensive attentions. [6,[21][22][23][24][25][26][27][28] Metal anodes, especially those with high-capacity and low-cost are promising alternative anode materials for LIBs in replace of graphite anode. [29][30][31][32][33][34] Generally, the metal anodes electrochemically alloy/ de-alloy with Li + to complete the battery reaction, which can store more energy than the intercalation/deintercalation mechanism in graphite. Table 1 displays the electrochemical properties of typical metallic anodes (Al, Sn, Zn, Mg, Sb, and Bi) with Li and graphite for comparison. While the graphite anodes suffer from low capacity (372 mA h g −1 ) and Li anodes suffer from severe safety issues caused by lithium dendrites, these metal anodes have many advantages in terms of high theoretical capacities, moderate operation potential for less dendrites formation, high abundance and low cost. [35] For example, aluminum has high theoretical capacity (993 mA h g −1 or 1411 mA h cm −3 for LiAl) with moderate potential plateau (≈0.38 V vs Li + /Li). [35,36] Considering both of the capacity increase and voltage drop by using metal anodes in a LIB model, Obrovac et al. calculated the volumetric energy increase in comparison to graphite based commercial battery (Table 1). [37] In such a model, the volumetric energy densities could be increased by different extents ranging from 10-42% when metal anodes were used. It is worth noticing that some recent studies have raised the idea of directly using metal foil as active anode material and simultaneously current collector. [38,39] This strategy can eliminate the usage of binder and conductive carbon black for anode preparation, simplify the battery processing steps, and also increase the loading amount of active materials, thus further enhancing the energy density and reducing the battery prices.While the metal anodes show good potential for application in high-performance LIBs, the main challenge for these metallic anodes is their large volume change caused by lithiation/delithiation process during cycling. [37,40,41] As the lithiation proceeds more deeply, the volume change becomes more severely for alloying anodes. For instance, the volume change of Sn (260%, Li 4.4 Sn) is larger than Al (97%, LiAl). The huge volume change could cause crack and pulverization of metal anodes, resulting in quick capacity decay and short cycling life. [42][43][44][45][46] Besides, metallic anode materials usually exhibited high first-cycle capacity loss due to their high reactivity withThe ever-growing market of portable electronic devices and electric vehicles has significantly stimulated research interests on new-generation rechargeable battery systems with high energy density, satisfying safety and low cost. With unique potentials to achieve high energy density and low cost, rechargeable batteries based on metal anodes are capable of storing more energy via an alloying/de-alloying process, in comparison to tradi...
