Energy storage devices play a key role in the clean energy transition, enabling the use of energy from renewable sources and electric mobility. Although Lithium-Ion Batteries (LIBs) have several desirable characteristics (such as pollution-free operation, high efficiency, long lifetime), [1] the rapid expansion of their market has raised concerns about the availability of the raw materials used, particularly Lithium and Cobalt, with projections predicting a shortage in less than ten years. [2]
The aim of the project HYNANOSTORE - Hybrid Nanostructured Systems for Sustainable Energy Storage - recently funded by an ERC Consolidator Grant, is to revolutionize the conventional battery electrode, based on Li insertion, and develop a new architecture, in which redox organic molecules anchored to a nanostructured electrode are the active part of the battery and are able to reversibly uptake and release electrons.
The nanostructured conductive scaffold, with tailored features and an extended surface area, immobilizes redox-active molecules, facilitates charge transport, and enhances interactions between active material and electrolyte. Preliminary results are presented in order to demonstrate the working mechanism of the proposed bio-inspired engineering system, which will lead to the introduction of a new concept for the realization of economically and environmentally sustainable energy storage devices, characterized by great versatility in terms of electrode materials and electrolytes.

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.
