    Abstract

    Stability of the electrolyte toward reduced oxygen species generated at the cathode is a crucial challenge for the rechargeable nonaqueous Li-O 2 battery. Here, we investigate dimethylformamide as the basis of an electrolyte. Although reactions at the O 2 cathode on the first discharge-charge cycle are dominated by reversible Li 2O 2 formation/decomposition, there is also electrolyte decomposition, which increases on cycling. The products of decomposition at the cathode on discharge are Li 2O 2, Li 2CO 3, HCO 2Li, CH 3CO 2Li, NO, H 2O, and CO 2. Li 2CO 3 accumulates in the electrode with cycling. The stability of dimethylformamide toward reduced oxygen species is insufficient for its use in the rechargeable nonaqueous Li-O 2 battery.
