The solid electrolyte interface (SEI) in sodium batteries influence the long-term performance and eventual degradation of the cell, hence an in depth understanding of their formation mechanism is important. This would aid better cell and electrolyte design to allow for longer lasting battery life and slower degradation.
According to current research, the solid electrolyte interface layer is a passivation layer formed on the surface of the anode during the first few charge-discharge cycles due to decomposition of the electrolyte. This decomposition is triggered by the difference in redox potential between the electrodes and the electrolyte.(1) Beyond this explanation, the SEI formation mechanism is still poorly understood, particularly with respect to the chemical reactions and species that are involved in its formation.
In this research we study SEI formation using electrochemical mass-spectrometry, to determine the gases evolved during the process. In addition, we utilise the time of flight secondary ion mass spectrometry technique (TOFSIMS) which is surface sensitive, to investigate the SEI components on the anode surface. Finally, we conduct electrochemical characterisation including electrochemical impedance spectroscopy, galvanostatic cycling and cyclic voltammetry, to give further insights into the relationship between SEI and electrochemical performance.
I would like to acknowledge the Damians Cummins Scholarship for providing PhD funding
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.
