Sodium-ion batteries (SIBs) are one of the most promising candidates to replace lithium-ion (LIBs) in grid-scale energy storage applications. The design high-performance anodes and fully understanding sodium mechanisms main bottleneck overcome. Herein, a vine shoot-based hard carbon anode was synthesized via hydrothermal carbonization followed by pyrolysis step (800 1200 °C). In addition water,...

the deposits of clinoptilolite (cli) in iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. the results showed that the absorption for ca2+ (7.5 ppm), cu2+ (50 ppm), zn2+ (40 ppm), cd2+ (40 ppm), pb2+ (500 ppm) and al3+ (5 ppm) were 95.2, 96.70, 93.30,99.12, 99.2 and 90.0 percents, respectively. the noteworth o...

Sodium-ion batteries (SIBs) are a promising grid-level storage technology due to the abundance and low cost of sodium. The development new electrolytes for SIBs is imperative since it impacts battery life capacity. Currently, sodium hexafluorophosphate (NaPF6) used as benchmark salt, but highly hygroscopic generates toxic HF. This work describes synthesis series borate salts, with electrochemic...

The low initial Coulombic efficiency (ICE) for the electrodes which stems from electrolyte decomposition and irreversible sodium uptake by material itself, is one of reasons limiting large-scale sodium-ion capacitors (SICs). Here, we report a simple but precise bifunctional pre-sodiation Nb2O5 anode (as typical example) using naphthalene/2-methyltetrahydrofuran as pre-sodiated agent. agent real...

RATIONALE Tandem mass spectrometry of phosphorylated ions can often yield a limited number of product ions owing to the labile nature of phosphate groups. Developing techniques to improve dissociation for this type of ion has implications for the structural characterisation of many different phosphorylated ions, such as those from nucleotides, pharmaceutical compounds, peptides and polymers. ...
