(a) Discharge–charge voltage profiles up to a capacity of 500 mAh g⁻¹, with a constant current density of 500 mA g⁻¹ of the Li-air cell with MoS₂ cathode and an ionic liquid/DMSO EMIM-BF₄/DMSO (25%/75%) electrolyte, over 550 cycles. The inset shows the capacity as a function of the number of cycles. (b) Dependence of the number of battery cycles in air on the number of deposition cycles used to form the anode-protection Li₂CO₃/C layer. Reproduced with permission from [362]. Copyright 2018 Nature.
