The pursuit of electrode materials with excellent electrochemical properties is critical to improving the performance of batteries and supercapacitors. Here, we report on our recent research progress and ongoing research on supercapacitors. By using a carbon mesoporous material (CMK-3, specific surface area = 1340 m2/g) as the matrix of the composite electrode, electrodes usually perform high power density because of the presence of the double-layer capacitance (EDLC). Integrated with functional material, it enables further adjustment of the properties toward the desired aspects. For example, we improve the energy density of CMK-3-based electrode under high-power operation mode with improved cyclic stability through the dispersion of SiO2 nanospheres on it [1]; hybrid with faradaic active polyaniline (PANi) and hydroquinone (HQ), we developed a PANi/CMK-3/HQ composite system with excellent cyclic stability and high specific capacitance [2]. On the other hand, we recently developed a novel design of manganese molybdate@nickel molybdate (MnMoO4@NiMoO4) nanorods-on-nanosheets core-shell structures [3]. This binder-free electrode demonstrates superior specific capacitance, energy density, power density, and cycling stability. Combining the abovementioned ideas, we are now developing a core-shell structure by using CMK-3 as the core and SmVO4 as the shell, and we expect this study to contribute to the development of innovative electrode materials for high-efficient supercapacitors.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
