제목 DFT calculations for role of non-aqueous electrolyte solvents in Li-O2 batteries
초록 The DFT calculations were performed to investigate the role of non-aqueous solvent for the oxygen reduction reaction kinetics in Li-air batteries. The LiCF3SO3/DMSO electrolyte was primarily assumed to be the most favorable for ORR kinetics from the IR analysis. The thermodynamic properties of the ORR reactions held during the formation of superoxide (O2-) ion and the sole discharge products lithium peroxide (Li2O2), and lithium oxide (Li2O) were calculated and analyzed to study the ORR kinetics of the stable salt LiCF3SO3 with three solvents namely dimethoxyethane (DME), dimethyl sulfoxide (DMSO), and acetonitrile (MeCN). The key role of LiCF3SO3/DMSO electrolyte compared to LiCF3SO3/DME and LiCF3SO3/MeCN was observed both in the gas and solution (water) phases.
