  • Patent number: 9336958
    Abstract: 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.
