本发明公开了一种锂硫电池用镍掺杂氧化铈/碳纳米管功能隔膜及其制备方法。以常规商业电池隔膜为基体，在其一侧表面铺设镍掺杂氧化铈/碳纳米管（Ni‑CeO2‑x/CNT）复合材料为功能层。其中，交织网状结构的碳纳米管具备质轻、导电性高和机械性能优异等特性，不仅能够对多硫化物发挥物理阻挡作用，还可为电池系统提供良好的电子传导路径。镍掺杂进入氧化铈晶格后，丰富了极性Ni‑CeO2‑x中氧空位缺陷，从而促使其高效吸附多硫化物，并加速催化多硫化物转化，有效抑制锂硫电池的“穿梭效应”。因此，基于Ni‑CeO2‑x/CNT功能隔膜所组装的锂硫电池呈现出高比容量、优异的倍率性能和循环稳定性。

The present patent of invention relates to aluminium-graphene nanocomposites with high electrical and thermal conductivity, and methods for obtaining same via microstructural control, and more specifically to the incorporation of multilayer graphene nanoplatelets (mGNP or few-layer graphene), comprising up to 10 layers, into pure commercial aluminium or aluminium alloys, using electric furnaces. The nanocomposites obtained comprise an aluminium matrix with dispersed graphene as the reinforcing phase, in proportions ranging from 0.1 wt% to 3 wt%. In order to obtain the nanocomposites, gravity casting techniques were employed in resistive and induction furnaces, with adaptations to prevent oxidation through the use of an inert gas atmosphere. The methodology employed enables a significant increase in electrical conductivity, ranging from 45% to 95% relative to the as-received commercial material, depending on the amount of graphene added. The thermal diffusivity of the nanocomposites also increased by 15% to 50%, with a possible maximum of around 0.5 wt% to 1 wt% of graphene. Similarly, the general physical properties exhibited marked improvements, although the rate of improvement decreased for nanocomposites containing more than 2 wt% of graphene.

The present invention relates to a solid-state rechargeable zinc-air battery featuring a novel bifunctional electrocatalyst, a dual-crosslinked polyacrylic acid hydrogel electrolyte, and a stannate-based additive for in situ zinc anode modification. The cathode comprises a gas diffusion layer coated with ruthenium-ruthenium oxide core-shell nanoparticles supported on nitrogen-doped graphene, providing enhanced bifunctional catalytic activity and stability. The anode consists of zinc metal modified in situ by a stannate-based additive to form a solid electrolyte interphase layer, effectively suppressing dendrite formation. The electrolyte membrane is a polyacrylic acid hydrogel, covalently and ionically cross-linked, and soaked in an aqueous solution containing potassium hydroxide, zinc acetate, and a stannate-based additive, resulting in improved mechanical strength, ionic conductivity, and battery safety. The integrated system delivers high power density, specific capacity, and robust cycling stability, offering a significant advancement in the field of solid-state zinc-air batteries.
