|Title||NANOPOROUS CERAMIC COMPOSITE METAL|
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.
