One of the most widely used electroanalytical methods for understanding the kinetics of composite battery electrodes is GITT – the Galvanostatic Intermittent Titration Technique [1,2]. At the same time, it is common for battery researchers to question the reliability of GITT measurements. The level of skepticism associated with GITT varies; some question its quantitative accuracy (but not much on otherwise trends), whereas others raise more serious questions on its relevancy for kinetics. The root causes for the unreliability of GITT are also perceived quite differently among researchers. Some believe that the unreliability is a result of poor implementation of the technique, implying that careful measurements could produce reliable results. Others believe that there are more fundamental limitations, dismissing any kinetic information obtained from GITT measurements. In this talk, we will isolate the implementation issues and focus on answering the question: "if the measurement protocol is optimized, can we extract relevant kinetic parameters from GITT measurements on composite battery electrodes?" We will take lessons from recent microscopic kinetics studies [3-7] and understand their implications from the perspective of using electroanalytical techniques such as GITT.

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.
