“…23 These regulation strategies belong to the category of lithium reduction reactions (LRRs), one type of metallic reduction reaction (MRR) which have huge advantages in fabricating diverse functional interface materials. 24,25 Due to the high activity of metallic lithium, LRRs are a quite special and highly efficient class among MRRs in material synthesis and interface regulation. They have been widely applied in the interface optimization of LMAs.…”

“…[12a,20] To address the above issues of unstable Li metal anode regarding volume change and high reactivity toward electrolyte and polysulfides, employing Li-based alloys as alternative anode materials affords a promising scheme. [21] Concretely, Li can alloy with silicon, tin, magnesium, aluminum, and many other elements and demonstrates electrochemical activity. [22] Alloy anodes with higher electrode potential versus Li deposition (0.1-0.6 V vs Li/Li + ) can relieve the corrosion reactions with polysulfides and other electrolyte components from the thermodynamic point of view.…”

Lithium–sulfur (Li–S) battery is identified as one of the most promising next‐generation energy storage systems due to its ultra‐high theoretical energy density up to 2600 Wh kg−1. However, Li metal anode suffers from dramatic volume change during cycling, continuous corrosion by polysulfide electrolyte, and dendrite formation, rendering limited cycling lifespan. Considering Li metal anode as a double‐edged sword that contributes to ultrahigh energy density as well as limited cycling lifespan, it is necessary to evaluate Li‐based alloy as anode materials to substitute Li metal for high‐performance Li–S batteries. In this contribution, the authors systematically evaluate the potential and feasibility of using Li metal or Li‐based alloys to construct Li–S batteries with an actual energy density of 500 Wh kg−1. A quantitative analysis method is proposed by evaluating the required amount of electrolyte for a targeted energy density. Based on a three‐level (ideal material level, practical electrode level, and pouch cell level) analysis, highly lithiated lithium–magnesium (Li–Mg) alloy is capable to achieve 500 Wh kg−1 Li–S batteries besides Li metal. Accordingly, research on Li–Mg and other Li‐based alloys are reviewed to inspire a promising pathway to realize high‐energy‐density and long‐cycling Li–S batteries.

“…[4,5] Studies have shown that the antimonybase alloy is an ideal option for K þ /Na þ storage due to high theoretical gravimetric capacity (660 mAh g À1 ) based on the multielectron reaction and relative safe voltage, which can effectively inhibit the continuous solidÀelectrolyte interface film. [6][7][8][9] Unfortunately, the severe volume change of antimony during the alloying/dealloying process will cause electrode pulverization and lead to rapid capacity fading, which hinders the application of antimony-based materials. To ameliorate the electrochemical performance of antimony anode, many effective methods have been actively explored.…”

Antimony‐based materials are promising anode candidates for Na‐/K‐ion batteries (SIBs/PIBs) but limited by the mediocre cycle performance due to the large volume change. Herein, a honeycomb‐like interconnected porous carbon framework embedded with CoSb nanoparticles is fabricated via a water‐soluble template‐assisted vacuum freeze‐drying technology followed by a heat‐treatment method. The CoSb nanocrystalline and 3D porous carbon matrix endow the CoSb@3DPCs composite electrode with a distinct structure, which buffers the volume expansion of Sb, shortens the diffusion distance of Na+/K+, and enhances the electronic conductivity. It exerts outstanding electrochemical properties in both SIBs and PIBs, such as remarkable cycling durability (the capacity is maintained at 211.2 mAh g−1 after 500 cycles for SIBs and 287.5 mAh g−1 for PIBs) and rate capability (144 mAh g−1 at 5 A g−1 for SIBs and 134 mAh g−1 at 5 A g−1 for PIBs). The kinetic analysis shows that up to 79% and 65% pseudocapacitance contributions for SIBs and PIBs are observed for CoSb@3DPCs at 4.0 mV s−1. Herein, an ingenious design route and simple preparation method toward exploring the high‐property electrode for PIBs and SIBs is provided, and broad application prospects in other electrochemical applications are opened up.
