    • Since pseudo-capacitance transition metal oxides (for example, MnO2) have high theoretical capacitance and are eco-friendly, inexpensive, and abundant in the natural world, pseudo-capacitance transition metal oxides are gaining attention as promising capacitor electrode materials. However, pseudo-capacitance transition metal oxides have relatively low electronic conductivity and limited charging and discharging rates, and it is therefore difficult to use pseudo capacitance transition metal oxides for high output power applications. If a plating process accompanying a liquid-phase precipitation reaction is performed on a nanoporous metal such as nanoporous gold (NPG) to deposit a ceramic material (for example, MnO2 or SnO2) on the surface of a core metal (for example, NPG), a nanoporous metal-ceramic composite having particular structural characteristics and comprising a metal core part and a ceramic deposition part can be obtained. This hybrid material is a good functional material and exhibits excellent functions when used as an electrode material for high-performance super capacitor (SC) devices or as an electrode material for LIB.
    • 由于假电容过渡金属氧化物(例如MnO 2)具有高的理论电容,并且在自然界中环境友好,价格低廉且丰富,因此假电容过渡金属氧化物作为有希望的电容器电极材料正在受到关注。 然而,伪电容过渡金属氧化物具有相对低的电子导电性和有限的充电和放电速率,因此难以在高输出功率应用中使用伪电容过渡金属氧化物。 如果在纳米多孔金属如纳米多孔金(NPG)上进行伴随液相沉淀反应的电镀工艺,以在核心金属(例如NPG)的表面上沉积陶瓷材料(例如,MnO 2或SnO 2) 可以获得具有特定结构特性并且包括金属芯部分和陶瓷沉积部分的纳米多孔金属 - 陶瓷复合材料。 该混合材料是用作高性能超级电容器(SC)器件的电极材料或用作LIB的电极材料时的功能材料,并且表现出优异的功能。
