Lithium-ion batteries (LIBs) are one of the most promising energy devices owing to their high power density and long-term stability. In particular, the graphite anodes have been predominantly used as the negative electrode due to the good cycling stability, electrolyte compatibility and low cost. However, graphite anode degradations have a significant impact on the overall battery capacity during battery operations. Notably, solid electrolyte interphase (SEI) formation and volume expansion known as the most common anode degradations are challenging to detect through the experiments, thus there has been a growing trend in using computational simulations for anode degradation research. However, most of the research related to the identification of graphite anode degradation mechanisms by the simulations have not considered the chemical and mechanical degradations at the same time during the battery operation process. Also, they underestimate the heterogeneous effect of the anode electrodes. Therefore, we present an electro-chemo-mechanical 4D-resolved model for anode degradation during various charging rates using the heterogeneous graphite anode structures. From this work, we identify a realistic representation of the correlation between chemical and mechanical anode degradations. Our model provides a comprehensive understanding of the complex anode degradation mechanisms.
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.
