In the first part of the talk, I will introduce recently developed methodology for elucidation of the most important electrochemical performance parameters for high energy density battery materials, including electrode/electrolyte interphase conducitivity and cationic transference numbers from electrochemical impedance spectroscopy, and bulk ion diffusion coefficients in electrolytes and electrodes from galvanostatic polarization. Here, detailed elucidation of spectra and equivalent circuit developement allows for extraction of charge transfer resistances and compext time/temperature behavior. In the second part of the talk, I will focus on application of such methodology on most promissing materials, such as Li/Na/K/Mg/Al metals in contact with contemporary liquid electrolytes, concentrated liquid (e.g. containing triple ions) and polymer electrolytes (above 40 wt% of salt), sustainable sodium cathodes and hard carbon anodes. In the case of metals, the findings show diversity of materials chemistry, with relevance of existence and potential corrosion of native oxide films, as well as dendrites. Finally, I will give an outlook on how to potentially develop future sustainable high performance battery materials.
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.
