Abstract：In order to explore the parameters under the optimal performance of the cotton-based Al-air battery,the parameters of electrolyte types,electrolyte concentrations,electrode area ratios,cotton cloth widths and cotton layers were studied to obtain the optimal performance parameters.The experimental results show that the Al-air battery has better electric performance and discharge performance in KOH electrolyte than in NaOH electrolyte.However,when the current density is 10 mA/cm2,the specific capacity of the battery in KOH electrolyte is 489 mAh/g,which is lower than that(547 mAh/g)in the NaOH electrolyte.The battery performance achieves the best when the KOH electrolyte concentration is 4 mol/L,the electrode area ratio is 1∶1,the width of cotton cloth is 10 mm,and the number of cotton layers is 1 layer.The peak power density is(23.51±0.27)mW/cm2,and the limit current density is(72.26±2.41)mA/cm2.
