Multifunctional Phosphate Monomer Enabling LiNO3 Solvation and In Situ Formation of Flame‐Retardant Gel Polymer Electrolyte for High‐Voltage Lithium Metal Batteries

Advanced Science, EarlyView.
A phosphorus‐containing multifunctional monomer is successfully synthesized to simultaneously enable the dissolution of lithium nitrate in ester‐based electrolytes and in situ form a flame‐retardant gel polymer electrolyte (GPE). The formed GPE effectively stabilizes the structures of both the cathode and anode, thereby achieving superior long‐term ...

Transition Metal Compounds for Aqueous Ammonium‐Ion Batteries: Storage Mechanisms and Electrode Design

Advanced Science, EarlyView.
Aqueous ammonium‐ion batteries leverage hydrogen‐bond‐mediated NH4+ storage in tunable transition metal compounds. Despite progress in Mn‐, V‐, Mo‐, and W‐based compounds, 2D LDHs, and MXenes, challenges like structural instability and slow kinetics persist. Future advances require robust host design, mechanistic understanding via operando studies, and

Effect of biofuel E85 combustion on fuel consumption in spark-ignition engines

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
Biofuels represent an alternative source of energy that should gradually decrease our dependence on crude oil. A rapid development of their use in combustion engines is above all the consequence of their very positive balance of emissions.
