Front Cover: Designing Alkylammonium Cations for Enhanced Solubility of Anionic Active Materials in Redox Flow Batteries: The Role of Bulk and Chain Length (ChemPhysChem 24/2024)

Résumé fourni par la source

The Front Cover illustrates the dissolution of vanadium bis-hydroxyiminodiacetate crystals. Our study focuses on enhancing solubility by modifying the alkylammonium cation structure through changes in chain length, adding bulky groups, and introducing carbon spacers. These structural adjustments disrupt crystalline packing, leading to improved solubility and higher energy density, which are crucial for developing efficient, high-performance nonaqueous redox flow batteries.
