Solid-state fluoride-ion batteries (FIBs) attract significant attention worldwide because of their high theoretical volume, energy density, and high safety. However, the large interfacial resistance caused by the point−point contact between the electrolyte and the electrode seriously impedes their further development. Using liquid-phase therapy to construct a conformal interface is a good choice to eliminate the influence of inadequate contact between the electrode and the electrolyte. In this study, a β-PbSnF 4 solid-state electrolyte with high room-temperature ionic conductivity is prepared, and a trace amount of the liquid electrolyte (LE) between the electrode and the electrolyte is introduced in order to minimize the interfacial resistance and enhance the cycle life. The Allen-Hickling simulations show that the introduction of an interfacial wetting agent (LE) can significantly reduce the energy barrier of charge transfer and mass transfer processes at the interface and reciprocate FIBs an enhanced interfacial reaction kinetics. As a result, the initial discharge capacity of the fabricated FIBs is 210.5 mAh g −1 and the capacity retention rate is 82.6% after 50 cycles at room temperature, while the initial discharge capacity of the unmodified battery is only 170.9 mAh g −1 and the capacity retention rate is 22.1% after 50 cycles. Therefore, interfacial modification with a trace amount of LE provides a significant exploration for the improvement of FIB performances.

As a novel type of clean and environmentally friendly energy storage and conversion technology, the zinc–air battery is considered a promising alternative to lithium-ion batteries. Nevertheless, because the oxygen reduction reaction (ORR) in the air cathode has the characteristic of a slow kinetic reaction, developing an electrocatalyst for ORR plays an important role in overcoming the limitation of low current density and large electrode polarization. To catalyze ORR, herein a high-efficiency and cheap ORR catalyst with a Fe3O4/Fe–N x dual catalytic active center (Fe–N–CS) via molten-salt-assisted pyrolysis is designed and prepared. The bulk iron oxide is successfully encouraged to break its chemical bonds by the sodium chloride molten salt and subsequently trapped by the porous nitrogen-doped carbon skeleton and reduced to Fe3O4 by a carbothermal process. Meanwhile, the graphitization degree of the carbon skeleton increases obviously and some Fe–N x sites are also generated because of the cooperation of Fe3O4 nanoparticles and Fe–N x species. It has been found that Fe–N–CS exhibits excellent ORR performance, e.g., half-wave potential up to 0.90 V and an onset potential of 1.04 V. In addition, Fe–N–CS shows better stability than Pt/C catalysts in chronoamperometry (I–T) tests, where Fe–N–CS maintains a 91% retention rate after 1200 s compared to Pt/C (75.8%). When the Fe–N–CS catalyst is used in zinc–air batteries (ZABs), it still shows better performance than the traditional Pt/C catalyst.

A lithium-rich manganese-based cathode material (LRMC) is currently considered as one of the most promising next-generation materials for lithium-ion batteries, which has received much attention, but the LRMC still faces some key scientific issues to break through, such as poor rate capacity, rapid voltage, capacity decay, and low first coulomb efficiency. In this work, homogeneous Li2ZrO3 (LZO) was successfully coated on the surface of Li1.2Mn0.54Ni0.13Co0.13O2 (LRO) by molten salt-assisted sintering technology. Li2ZrO3 has good chemical and electrochemical stability, which can effectively inhibit the side reaction between electrode materials and electrolytes and reduce the dissolution of transition metal ions. Thus, the as-prepared LRO@LZO composites are expected to improve the cycling performance. It can be found that the discharge specific capacity of LRO is 271 mAh g–1 at 0.1 C, and the capacity retention rate is still 93.7% after 100 cycles at 1 C. In addition, Li2ZrO3 is an excellent lithium-ion conductor, which is prone to increasing the lithium-ion transfer rate and improving the rate capacity of LRO. Therefore, this study provides a new solution to improve the structure stability and electrochemical performance of LRMCs.
