"Revealing the mechanism of saturated ether electrolyte for improving t" by Jin ling Ma, Wen chao Zhang et al.
Abstract Na-O batteries have been considered as promising energy storage systems due to their high energy density and low cost. Their poor cycle life, however, and their unclear interfacial formation mechanisms have greatly hindered the development of Na-O batteries. In this work, compared to the commonly used ether-based electrolyte (0.5 M sodium trifluomethanesulfonate in tetraethylene glycol dimethyl ether), its saturated electrolyte is employed for Na-O batteries to achieve around four times longer cycle life. Both experiments and simulations suggest that the enhanced cycling stability...
