The rechargeable alkali metal-ion batteries (RAMIBs) are highly promising candidates for next-generation efficient energy storage devices, owing to their outstanding theoretical specific capacities and extremely low electrochemical potentials. However, RAMIBs possess unsuitable lifespans, mechanical durability inevitable side reactions attributable inherent severe volumetric/structure alteration during the charge-discharge cycles. These hitches could be solved using porous multimetallic alloy-based anodes, due impressive capacities, working potential, cost, earth-abundance, which can meet sustainability practical application needs. Meanwhile, great surface area, electrical conductivity, structural stability, ability accommodate generated metal ions yield satisfactory coulomb efficiency long durability. Immense efforts dedicated rationally designing anodes RAMIBs, so it is essential provide timely updates on this research area. Herein, we reviewed recent advances in (i.e., Sn, Mn, Mo, Co, V, Fe) lithium-ion batteries, sodium-ion potassium-ion batteries. This rooted engineering approaches template-based, hydrothermal/solvothermal, chemical reduction, deposition, sol-gel, electrospinning) fundamental insights mechanisms, key parameters, calculations) precise evaluation changes, mechanisms by various experimental, theoretical, in-situ analysis optimizing performance. Also, recycling circular economy were discussed. Eventually, highlighted current drawbacks provided proposed perspectives solve these issues enable utilization of such large-scale applications.

Abstract To investigate the potential of MXene‐catalyzed electroreduction carbon dioxide towards achieving highly efficient ECO 2 RR, this study engineered an S ‐anchoring site on Ti 3 C T x MXene for Zn ion coordination. The findings revealed that was uniformly distributed across surface and interface, either replacing or integrating with functional groups, effectively coordinating Zn. Subsequently, nanoparticles were synthesized leveraging defect‐induced self‐reduction capability support. presence facilitated rapid electron transfer to Zn, accelerated activation dioxide, endowed Zn‐S‐MXene a larger active area, enhanced RR selectivity, faster charge rate. Consequently, CO selectivity significantly enhanced, reaching impressive FE 89.7%. This offers novel perspectives utilization atomic modifications in materials design optimization through strategic pairing metal ions.

Abstract The trade‐off of the Volmer reaction for *H formation and Heyrovsky/Tafel Reaction desorption is a crucial challenge in alkaline hydrogen evolution (HER). Thus, aside from conventional construction bifunctional active sites to accelerate water dissociation step, electronic retrimming each metal site also non‐negligible. Herein, an efficient HER electrocatalyst combining Pt single‐atoms nanoparticles on etched boron nitride (eBN) coated carbon nanotube (Pt‐eBN@CNT) synthesized, where both Heyrovsky steps are promoted by synergistic adsorption composite electron‐withdrawing effect eBN carrier, respectively. proposed catalyst shows impressive performance media with overpotential 25.1 ± 1.7 mV at 10 mA cm −2 , TOF 17.1 1.3 s −1 0.15 V vs RHE under extremely low loading 6 µg (catalyst 0.77 mg ), significantly better than those commercial benchmark Pt/C (44.2 4.1 mV, 0.9 0.1 ; 156.1 0.6 1.6 ) same conditions.
