Despite the continuous progress in research and development of Ti3C2Tx (MXene) electrodes for high-power batteries supercapacitor applications, role anions electrochemical energy storage their ability to intercalate between MXene sheets upon application positive voltage have not been clarified. A decade after discovery MXenes, information about possibility anion insertion into restacked electrode is still being questioned. Since potential stability range diluted aqueous electrolytes severely...
The emerging interest in aqueous rechargeable batteries has led to significant progress the development of next-generation electrolytes and electrode materials enabling reversible stable insertion various multivalent ions into electrode's bulk. Yet, despite its abundance, high salt solubility, small ionic radius, use manganese for energy storage purposes not received sufficient attention. Herein, we present Mo6S8 (Chevrel phase) as an anode Mn2+ insertion. By careful optimization electrolyte...
Among the examined organic electrodes for aqueous mono and multivalent ions batteries, polyimide is considered a promising candidate because of its high capacity good cyclability in different electrolyte solutions. While most studies so far were focused on energetic performance anodes, much less known about their charge storage mechanism particularly how such are affected by solvation properties inserted cations. Using situ EQCM-D, direct assessment cationic fluxes hydration shells...
Extensive efforts are currently underway to develop safe and cost-effective electrolytes for large-scale energy storage. In this regard, water-based may be an attractive option, but their narrow electrochemical stability window hinders realization. Although highly concentrated fluorinated have been shown effective in suppression of water splitting, enabling significant widening the applied potential range, they utilize expensive salts (e.g., lithium bis(trifluoromethane sulfonyl) imide...
Being nearly unlimited natural resource containing mostly Na cations, the use of seawater as an electrolyte solution (aka batteries) for electrochemical energy storage has received growing attention. To date, vast majority studies have focused on in Na-metal batteries protected by ion-conductive membranes hermetic to water. These systems, however, are complex and expensive, suffer from a short cycling life. Here, we present alternative that utilize polyimide anodes. With its high capacity...
Atox1 is a human copper metallochaperone that responsible for transferring ions from the main transporter, hCtr1, to ATP7A/B in Golgi apparatus. interacts with Ctr1 C-terminal domain as dimer, although it transfers monomeric form. The binding site dimer involves Cys12 and Cys15, while Lys60 was also suggested play role binding. We recently showed can adopt various conformational states, depending on interacting protein. In current study, we apply EPR experiments together hybrid quantum...
Metallochaperones are responsible for shuttling metal ions to target proteins. Thus, a metallochaperone's structure must be sufficiently flexible both hold onto its ion while traversing the cytoplasm and transfer or from partner protein. Here, we sought shed light on of Atox1, metallochaperone involved in human copper regulation system. Atox1 shuttles main transporter, Ctr1, ATP7b transporter Golgi apparatus. Conventional biophysical tools such as X-ray NMR cannot always various...
Disordered carbons are promising anode materials for sodium ion batteries. However, a major drawback of these is their low coulombic efficiency in the first cycles, which indicates parasitic reactions. Such reactions can be suppressed by alumina coating on surface anodic materials; more ions then available electrochemical activity, and less electrolyte solution lost. On other hand, some pores edge sites passivated no longer reversible reaction with ions; hence, contribution eliminated,...
The optimal performance of organic electrodes for aqueous batteries requires their full compatibility with selected electrolyte solutions. Electrode materials having 1-3-dimensional structures variable rigidity possess a confined space in structure filled water and Depending on the geometry, insertion extraction ions into electrode are often coupled incorporation/withdrawal molecules. Aside from scientific interest understanding charging mechanism such systems, co-insertion solvent molecules...
The need for low-cost, high-safety batteries large-scale energy storage applications has sparked a surge in research of rechargeable aqueous batteries. While most efforts are focused on the development electrolyte formulations and electrode materials, it appears that current collector impact battery performance is frequently overlooked. Even though traditionally thought as an inactive component, included density calculations, making its activation desirable. Furthermore, poor selection can...
The application of layered oxide compounds as cathode materials for sodium-ion batteries is considered a promising direction the development high-energy Na-ion batteries.
