Abstract

The application of rechargeable Lithium-air batteries in devices with capability of energy storage has been taken into consideration extensively. There are many methods to increase the performances of these batteries, such as using an appropriate catalyst and electrolyte. In the present research, Ppy/Co/Fe nanocatalyst was synthesized by using chemical precipitation and it was characterized using FT-IR, Raman, SEM, and XRD. The results indicated that the nanocatalyst with particle sizes of 35 nm has been synthesized successfully. To evaluate the effect of nanocatalyst, the battery was constructed and the experiments revealed that its power is very greater compared to the battery without nanocatalyst. Also, the battery containing nanocatalyst has more energy storage. The results of cyclic voltammetry indicated that due to the presence of PPy/Co/Fe nanocatalyst, the reversibility of cathode is increased significantly in comparison to the battery without nanocatalyst. The carbon black in the structure of nanocatalyst leads to increase the capacity of the battery because it improved the catalytic behavior of nanocatalyst. In was found that, in a usual cycle of charge/discharge process, the discharge process takes place longer time which is indication of long lifetime of the battery.
