Summary: In this study, a synergistic effect between carbon nanotube (CNT) network and atomic layer deposition (ALD) of TiO2 is reported. The CNTs and TiO2 work together to capture zinc ions and suppress dendrite growth, resulting in uniform deposition during repeated cycles. The modified anode (TiO2-CNT@Zn anode) exhibits high plating/stripping reversibility and ultralong lifespan. Furthermore, the Zn-MnO2 battery with the TiO2-CNT@Zn anode shows enhanced cycling stability.

Summary: In this study, the capacity decay mechanism of Zn-MnO2 batteries with manganese acetate as an electrolyte additive was demonstrated. It was found that zinc hydroxide sulfate has a beneficial effect on the battery capacity, but the product ZnMn3O7·2H₂O converted from basic zinc sulfate is an irreversibility inert material leading to rapid capacity fading. Notably, with an increased low cutoff voltage, the battery showed a high capacity and excellent stability. This research provides a new perspective for the development of Zn-MnO2 batteries.

Summary: The growth of dendrites in zinc-ion batteries (ZIBs) is effectively inhibited by coating the Zn anode with a poly(carbazole)-carbon nanotubes (PCz@CNTs) composite. The homogeneous and fiber-like growth-free Zn deposition during charging cycles is confirmed by electron microscopy analysis. A vanadium oxide nanorods-porous graphitic flakes (V6O13 NRs@PGFs) composite is used as cathode, providing high ion diffusion and many vacant sites for Zn2+ ion ingress and egress. The non-aqueous ZIB with V6O13 NRs@PGFs//PCz@CNTs@Zn achieves remarkable performance, including a capacity of 286 mAh g(-1) after 300 cycles with 98% capacity retention, energy density of 172 Wh kg(-1), and nominal voltage of 1.8 V. Compared to its analog ZIB with V6O13 NRs@PGFs//Zn (193 mAh g(-1) and 80% capacity retention), significant enhancement is observed. The PCzCNTs overlayer ensures long lifespan, ultra-safe operation, cost-effectiveness, and easy scalability, providing a solution for metal-ion batteries with dendrite-free and long-term cycling stability.

Summary: The current lithium-ion batteries (LIBs) are insufficient to meet the growing demands of the battery industry, leading to extensive research on new anode materials. Ni-based anode materials have been widely explored due to their higher theoretical capacity, longer cycle life, and environmental friendliness. This review focuses on the different morphologies of NiO-based materials and their electrochemical properties. It has been found that the performance of NiO-based anodes for LIBs is influenced by factors such as morphology, crystallinity, particle size, surface area, and porosity. Carbon-supported and metal oxide doped composites of NiO structures exhibit higher specific capacities compared to pure NiO, but the issue of capacity drainages needs to be further investigated.

The cathode, prepared by electrodepositing poly(4,4'-oxydianiline) onto mesoporous activated carbon, delivers a high areal capacity of 5.42 mAh cm-2. Due to the use of different electrolytes at the cathode and anode sides, this aqueous Zn-organic battery operates within an elevated voltage window of 1.3-2.5 V and exhibits a high discharge median voltage of -2 V. Furthermore, the optimization of electrolyte concentration and the use of additives to improve the Zn anode performance are systematically studied.

Summary: By using acetone as an electrolyte additive, an electrical double layer (EDL) reconstruction strategy is proposed to solve the dendrite growth and side reactions issues in Zn deposition, improving the depth of discharge. Experimental and theoretical simulation results show that the adsorption priority of acetone creates a water-poor inner Helmholtz layer, while the hydrogen bonding effect between acetone and water weakens the Zn2+ solvation. This rearrangement of ions/molecules in EDL suppresses hydrogen evolution, promotes the Zn2+ diffusion kinetics, and guides homogeneous Zn nucleation and growth.

Summary: The anode-cathode interplay is an important factor in the degradation of aqueous zinc ion batteries (AZIBs). In this study, Al-2(SO4)(3) is used as an electrolyte additive to manipulate OH-mediated communication between the Zn anode and NaV3O8.1.5H(2)O (NVO) cathode, improving the stability of V-based AZIBs. The hydrolysis of Al3+ creates a strong acidic environment, prolonging the anode lifespan and reducing interfacial OH accumulation. The acidified electrolyte alleviates undesired dissolution and phase transition, resulting in improved cycling stability for Zn parallel to NVO batteries.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
