However, the practical application of the LOB is obstructed by the high kinetic barriers and large overpotentials. Hence, a novel magnetic field assisted LOB (MF-LOB) is developed with ferromagnetic FeCo₂O₄ nanowires as catalyst that can improve the ORR and OER kinetics through the application of a moderate magnetic field. The FeCo₂O₄ nanowires are magnetized into nanomagnets with high spin polarization under a magnetic field, which is beneficial to the adsorption of O₂-intermediates and transfer of electrons. Equally, the MHD effect contributes to the mass transport and diffusion including O₂ and Li⁺. The generation and oxidation of Li₂O₂ are promoted for the MF-LOB based on FeCo₂O₄ nanowires due to the high spin polarization and MHD effect. The MF-LOB based on FeCo₂O₄ nanowires shows a lower overpotential of 0.89 V and longer cycle life of 150 cycles than those (1.22 V and 53 cycles) of the LOB without the magnetic field.

However, surface side reactions, such as Zn corrosion, hydrogen evolution reaction, and dendrite growth, lead to low reversibility of Zn anode. This study introduces a time-saving and simple solution-dipping method to address above issues by spreading ultrathin Poly (vinyl formal) (PVF) protective layer on the surface of Zn anode (denoted as PVF@Zn). Owing to its abundant oxygen-containing functional groups, PVF molecule exhibits not only highly adhesive force with Zn metal surface but also higher zincophilicity with Zn²⁺ ions. The former effectively prevents direct contact between electrolyte and Zn anode as well as guides a three-dimensional (3D) diffusion mode of Zn²⁺ plating, the latter reduces the Zn nucleation energy barrier as well as enhances the uniformity of Zn deposition. Meanwhile, the hydrophilic and ion conductivity characters endow the PVF film with abundant nucleation sites and homogenous electric field distribution, further guaranteeing an even Zn deposition. Moreover, the outstanding mechanical strength and elasticity of the PVF film can withstand the volume variation during Zn plating/stripping, which is conducive to inhibit the growth of dendrites. Consequently, symmetrical cells assembled by the PVF@Zn electrodes deliver dendrite-free plating/stripping and an ultra-long stable cycle of 4900 h at 0.5 mA cm⁻², 1.0 mAh cm⁻².
