Abstract
We proposed that Mn-doped TiO2 nanosheets (Mn-TiO2 NS) as cathode catalyst improved the electrochemical performance of lithium-air batteries. Firstly, rutile Mn-TiO2 NS were calcined by a facile hydrothermal treatment method. Secondly, polyvinylidene fluoride (PVDF) was dissolved in an N-methyl-2-pyrrolidone (NMP) solvent. KB and Mn-TiO2 NS were mixed with a PVDF/NMP solution to fabricate a cathode slurry. Lastly, the cathode slurry was coated onto circular carbon paper (diameter=15 mm) and dried at 60 degrees C for 3 h in the oven to obtain the air cathode. As expected, lithium-air cells based on KB and Mn-TiO2 NS electrode exhibit an improved overpotential of 1.24 V and a high discharge capacity of 9374.23 mAh.g(-1) at the current density of 250 mA.g(-1). It suggests that Mn-TiO2 NS is a promising catalyst for Li-O-2 batteries.
