Screening electrode materials in conventional battery research is time-consuming due to the lengthy and intricate preparation process, where multiple parameters directly influence electrochemical performance. In this work, we present ADEL, an affordable module for the Automated preparation of high-loading Drop-cast ELectrodes, integrated within MAI...

By applying solid-state 6,7 Li NMR, we reveal a redox reaction sequence of solid solution and biphasic transition and highlight the existence of intermediate species in non-stoichiometric transition metal-ordered high-voltage LNMO cathode reaction vs. Li.

An operando dual-edge X-ray absorption spectroscopy on both transition-metal ordered and disordered LiNi0.5Mn1.5O4 during electrochemical delithiation and lithiation was carried out. The large data set was analyzed via a chemometric approach to gain reliable insights into the redox activity and the local structural changes of Ni and Mn throughout t...

The depletion of fossil fuels, the rapid evolution of the global economy, and high living standards require the development of new energy‐storage systems that can meet the needs of the world's population. Metal–oxygen batteries (M=Li, Na) arise, therefore, as promising alternatives to widely used lithium‐ion batteries, due to their high theoretical...

Energy storage is a major challenge for modern society, with batteries being the prevalent technology of choice. Within this area, sodium oxygen (Na-O2) batteries have the capability to make a step change, thanks to their high theoretical energy density. In order to facilitate their use, the development of electrolytes is critical to overcome certa...

Triphylite-NaFePO4 attracts considerable attention as cathode material for sodium-ion batteries due to its theoretical capacity (154 mAh/g), sharing also the excellent properties of the analogous triphylite-LiFePO4 used in commercial lithium-ion batteries. In this work, Triphylite-NaFePO4 is synthesized from Triphylite-LiFePO4, by a low-cost, eco-f...

Epoxy–silica hybrids (i.e., as such, enriched with TiO2 and cerium-doped TiO2 nanoparticles), based on a bisphenol (BPA)-free cycloaliphatic precursor, were designed for potential applications as stone conservation multifunctional materials. To this aim, nanoparticles were specifically prepared and their suitability for incorporation into the hybri...

Carbon coated tin phosphide is synthesized by an easily scalable ball milling method. The electrochemical performance of Sn4P3/C electrodes is explored using different combinations of carbonate and ether based solvents. Our experiments reveal that a remarkable improvement in the specific charge of Sn4P3 anodes can be obtained by using a combination...

NaFePO4 with an tryphilite structure is one of the most attractive materials for sodium ion batteries (NIBs) due to its high theoretical capacity, 154 mAh g-1, with an average voltage of 2.95 V vs. Na+/Na, which allows to design batteries with a high theoretical energy density (450 Wh kg-1). NaFePO4 is analogous to LiFePO4[1], a commercial material...

Olivine-NaFePO4 is one of the most attractive materials for sodium ion batteries, since its exhibits one of the highest reversible capacities reported up to date for a polyanionic Na-ion cathode material (154 mAh g-1) and maintains some of the exceptional features of LiFePO4[1], its Li counterpart: reaction within a narrow voltage range inside the...
