Findings from Lanzhou University in the Area of Nanotechnology and Microtechnology Described (Co@Co3O4 Core-Shell Three-Dimensional Nano-Network for High-Performance Electrochemical Energy Storage)

By a News Reporter-Staff News Editor at Energy Weekly News -- Investigators publish new report on Nanotechnology and Microtechnology. According to news reporting from Lanzhou, People's Republic of China, by VerticalNews journalists, research stated, "An alternative routine is presented by constructing a novel architecture, conductive metal/transition oxide (Co@Co3O4) core-shell three-dimensional nano-network (3DN) by surface oxidating Co 3DN in situ, for high-performance electrochemical capacitors. It is found that the Co@Co3O4 core-shell 3DN consists of petal-like nanosheets with thickness of

The news correspondents obtained a quote from the research from Lanzhou University, "X-ray photoelectron spectroscopy by polishing the specimen layer by layer reveals that the Co@Co3O4 nano-network is core-shell-like structure. In the application of electrochemical capacitors, the electrodes exhibit a high specific capacitance of 1049 F g(-1) at scan rate of 2 mV/s with capacitance retention of similar to 52.05% (546 F g(-1) at scan rate of 100 mV) and relative high areal mass density of 850 F g(-1) at areal mass of 3.52 mg/cm(2). It is believed that the good electrochemical behaviors mainly originate from its extremely high specific surface area and underneath core-Co 'conductive network'. The high specifi c surface area enables more electroactive sites for efficient Faradaic redox reactions and thus enhances ion and electron diffusion."

According to the news reporters, the research concluded: "The underneath core-Co 'conductive network' enables an ultrafast electron transport."
