Sodium-ion batteries (SIBs) is one of the more promising battery technologies that are starting to see commercialisation, were the low cost, abundance of necessary raw materials, higher safety and power and similar energy densities compared to lithium-ion batteries (LIBs) are often mentioned as their key advantages. SIBs, due to their great similarities with LIBs have seen a rapid development. One of the key differences, however, is the carbonaceous negative electrode, where in the case SIBs is not possible the use of graphite. This is due to Na+ not forming stable intercalation compounds with graphite unlike for LIBs. But, it was discovered by Jache et al. 1 that Na+ can form stable ternary graphite intercalation compounds by using ethers as the solvent electrolyte through a solvent co-intercalation mechanism, thus enabling the use of graphite in SIBs. Although the co-intercalation of solvent molecules with sodium cation leads to a large increase in the graphite framework, the cycle life and rate capability of the reaction are excellent. 2, 3
This sparked additional interest in the phenomenon, where many electrolyte solutions have now been explored for several metal-ions (Li+, Na+, K+ as well as Mg2+ and Ca2+) showing that when electrochemical solvent co-intercalation occurs the redox reaction, both capacity (stoichiometry) and potential, becomes dependent on the exact electrolyte formulation.4 Hence systems with solvent co-intercalation offers an extremely diverse chemistry.2, 4
This presentation aims to summarize the ongoing research endeavors concerning electrochemical solvent co-intercalation phenomena. Our exploration spans from fundamental inquiries regarding the nature of the reactions involved to methodologies for detecting solvent co-intercalation.5 We also present other electrode materials (in the transition dichalcogenide family) that can be identified as “co-intercalation electrode” when using a specific electrolyte composition (otherwise, conventional intercalation process will occur).6

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.
