Summary: The study constructs 2D hierarchical NaV6O15@VO2(M)@V2C composites through one-step oxidation of Na-ion intercalated V2C MXene in CO2, where VO2(M) nanosheets are confined by NaV6O15 nanorods and V2C MXene. Due to the intrinsic merits of monoclinic VO2(M) and a dual conductive confinement system composed of the outer NaV6O15 nanorods and the inner V2C MXene, NaV6O15@VO2(M)@V2C exhibits superior electrochemical performance as an anode for LIBs. It delivers an outstanding reversible discharge capacity of 408.1 mAh g-1 at 100 mA g-1 after 100 cycles, as well as good cycling stability at 1 A g-1, which maintains capacity of 204.5 mAh g-1 after 400 cycles with a coulombic efficiency of 99.63%.

Summary: Here, a new test procedure for lithium ion cells is developed to induce cell internal defects under more realistic conditions. Lithium plating, a common phenomenon in aging graphite-based lithium-ion battery cells, is chosen as the trigger and is induced systematically and reproducibly through electrochemical cycling. The behavior of cells differed based on the outcome of the test, allowing for classification into categories. It is the consequences of the lithium plating, such as degradation reactions and increased inner resistance, that cause safety critical behavior of the cells, rather than the plating and dendrite growth itself.

Summary: This study proposes a strategy for the protection of negative electrodes in aqueous zinc ion batteries (AZIBs) by artificially constructing a Ni-Zn alloy layer as a solid-electrolyte interface (SEI). The Ni-Zn alloy layer acts as a dynamic shield at the electrode/electrolyte interface, guiding the horizontal deposition of zinc and suppressing dendrite formation. The Ni-Zn alloy symmetric cell exhibits significantly improved cycle life and stable operation.

Summary: In aqueous Zn-ion batteries (AZBs), the use of Zn metal as an anode has advantages of high energy density, inherent safety, and low cost. However, direct contact between electrolytes and Zn metal leads to corrosion and dendrite growth, compromising the calendar life and Coulombic efficiency (CE) of AZBs. A novel hydrophobic-zincophilic bifunctional layer (HZBL-Zn) is introduced on the Zn surface to provide hydrophobic and uniform pathways for zinc ions.

Summary: In this study, a sulfur-modified Fe-N-C catalyst with a controllable local coordination environment was constructed, where Fe is coordinated with four in-plane N and an axial external S. The external S atom affects both the electron distribution and spin state of Fe in the FeN4 active site. The appearance of higher valence states and spin states for Fe demonstrates an increase in unpaired electrons. With these characteristics, the adsorption and desorption of reactants at FeN4 active sites are optimized, thus promoting the activity of the oxygen reduction reaction. This work explores the key point of electronic configuration and coordination environment tuning of FeN4 through S doping and provides new insight into the construction of M-N-C-based oxygen reduction reaction catalysts.

The development of a Na0.71Li0.22Al0.05Mn0.73O2 (NLAM) cathode material with Al substitution strategy strengthens the TMO2 skeleton and TM-O bonds, inhibiting excessive lattice oxygen oxidation. NLAM exhibits high capacity and good cyclability. In situ characterizations and theoretical calculations support the findings and provide insight for designing cathodes with reversible anionic redox.

Summary: Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition. Based on underpotential deposition (UPD), an escort effect of electrolyte additives for uniform Zn deposition at the atomic level is proposed. With nickel ion (Ni2+) additives, metallic Ni deposits preferentially and triggers the UPD of Zn on Ni, facilitating firm nucleation and uniform growth of Zn while suppressing side reactions. The optimized cell operates for over 900 h at 1 mA cm(-2), more than 4 times longer than the blank one, indicating the significance of this work.

Summary: Efficient boron-based electrolyte for rechargeable magnesium batteries was successfully prepared through a simple one-step mixed reaction. The modified anion structure obtained by adjusting the composition and ratio of boron-based salts in the electrolyte had lower HOMO states. The electrolyte not only formed a MgF2-rich solid electrolyte interphase (SEI) layer to inhibit electrolyte decomposition and enhance cycling stability of Mg anodes, but also demonstrated feasibility in Mg/CuS and Mg/Mo6S8 full batteries assembly. The dual regulation strategy of anions and interfaces offers a novel idea for designing efficient electrolytes in rechargeable magnesium batteries.

Summary: VO2(B) is a leading candidate cathode material for AZIBs, but the primary challenges of slow kinetics and limited actual capacity have not been resolved yet. In this study, the effects of ion doping on VO2(B) were investigated, and it was found that heteroatom (Cr, Mo, and W)-doped VO2(B) cathode can verify the theoretical calculation results. Among them, Mo-doped VO2(B) showed the best electrochemical performance, with excellent initial specific capacity (264.6 mA h g(-1)) and retention rate (81.4 %) at 3.0 A g(-1). It also exhibited a faster Zn2+ ion diffusion coefficient (2.1x10(-8) vs 2.6x10(-9) cm(2) S-1) compared to pure VO2(B). Furthermore, it achieved a promising energy density of 207.3 Wh kg(-1) at 0.1 A g(-1) and a power density of 3094.5 W kg(-1) at 5.0 A g(-1). This finding provides insights into the modification mechanism of heteroatom-doped materials and can guide electrode design for improved performance.

Summary: Compared with traditional lithium-ion batteries and Li-other group VIA elements batteries, Li-Te batteries have high specific volumetric capacity and superior electrical conductivity, making them important for portable electronics and electric vehicles. However, their Achilles’ heel is the huge volume change and dissolution of polytellurides during cycling. In this research, a cathode material based on Te-filled CNTs was synthesized, which showed improved reaction kinetics and electrochemical reversibility. The use of nanoscale cavities in the CNTs stabilized the polytellurides and enhanced the utilization and cycling stability of the cathodes in Li-Te batteries.

Summary: In this study, an interface engineering approach is used to address the challenges of Li dendrite propagation and interfacial incompatibility in solid-state electrolytes for Li metal batteries. By introducing an electronic rectifying interphase consisting of a p-Si/n-TiO2 junction and an external Al layer, electron infiltration into the electrolyte is effectively restrained, leading to dendrite reduction. Experimental results confirm the electronic rectifying behavior of the interphase, as well as improved interface compatibility and battery lifetime. X-ray computed tomography observation confirms the reduction of Li dendrite propagation behavior.
