The development of high-performing garnet based all-solid-state batteries requires intensive knowledge of the materials and processes throughout the whole cycle life of the battery to ensure ecological and economical battery production. Life-cycle analysis of the battery production line uncovered the production of raw materials and the temperature treatment steps as the crucial factors. Therefore, a better understanding of the garnet-based ceramic cathodes is needed.
3D analysis and reconstruction of the cells allowed the modelling of realistic microstructures and connects them to experimental data. This realistic cell model facilitates a deeper understanding of the limiting factors towards higher energy densities. Based on these findings, an optimized microstructure was derived. With the introduction of sequential tape-casting and an optimized sintering strategy to mitigate stresses in the material during high-temperature treatments, cathodes with this optimized microstructure were produced. These cathodes show a significant increase in the available areal specific capacity of ceramic batteries.
The introduction of advanced processing methods, as well as significant improvement of the anode side, an analysis of the degradation mechanisms in the cathodes during operation helped uncover the nature of capacity losses during cycling. Based on these findings, a strategy for direct recycling of the ceramic cells was derived, regaining over 40% of the initial capacity after complete degradation.
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.
