Аннотация:Developed architecture for a lithium-oxygen battery (LOB) positive electrode based on carbon nanotubes with large-volume pores and a Li-Nafion solid polymer electrolyte (SPE) is engineered. At a Li-Nafion/C ratio of 0.2, a discharge capacity of up to 27000 mA h g−1 achieved. SPE-LOB sustains 182 cycles as compared to 121 cycles for LOB with liquid electrolyte. The high characteristics of the SPE-LOB can be explained in terms of the prevention of the flooding of gas pores, decrease in the ohmic resistance of the system and formation of independent transfer channels of O2 and Li+.
