Boosted after their commercialization in 2023, Sodium-ion batteries (SIBs) are well positioned to become the energy storage system of choice for stationary applications and complementary to Li-ion in electromobility. This is a sustainable and low-cost technology that does not rely on critical raw materials and guarantees widespread availability free of geopolitical constraints, hence avoiding most of the drawbacks of lithium-based technology. However, SIBs energy density has not yet reached the performance levels of LiFePO4-based lithium-ion batteries (LIBs), partially hindering their application in other sectors. One of the most promising cathode materials, namely the P2-type layered oxides, is affected by irreversible sodium consumption during solid electrolyte interphase (SEI) formation and low sodiation degree: about 2/3. These two factors are the main drawbacks behind SIB’s underperformance. Solutions to these problems have been attempted with limited success and significantly hindering the fabrication cost of Na-based cells. We had a look at quick and low-cost metallization processes used in low value products, such as candy wrapping, to develop a scalable and cost-effective sodiation process based on Na thermal evaporation. This method solves the incomplete sodiation degree of P2-type sodium layered oxides, thus overcoming the first irreversible capacity as demonstrated by manufacturing and testing all solid-state Na doped-Na~1Mn0.8Fe0.1Ti0.1O2ǀǀPEO-based polymer electrolyteǀǀNa full cells. This polymer has proven to be suitable for other cell configurations with sodium-deficient electroactive materials that will be presented here. The proposed sodium physical vapor deposition method opens the door for an easily scalable and cost-efficient strategy to incorporate any metal deficiency in the battery materials, pushing further the battery development.

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.
