Batteries That Charges On Air EEE Final Project Report

This Batteries That Charges On Air EEE Final Project Report examines the properties of this unique system in terms of the effects of solubility’s of reactants and products in both non aqueous and aqueous electrolyte solutions.

The carbon based Li-ion batteries used currently fall short in meeting the requirements of utilization for renewable energy, electrification of transportation, smart grid and portable devices with regard to energy density, power density and cost. Metal/air batteries use oxygen directly from the atmosphere to produce electricity. The cathode active material, oxygen, does not have to be stored in the batteries, which allows for higher total energy capacity in a smaller designed package. Very high energy density can be achieved due to essentially unlimited cathode capacity. Our model predicts that the overall theoretical energy density of polymer electrolyte Li/air battery could be as high as 2790 Wh/kg and 2800 Wh/L, which is comparable to gasoline-air combustion engines. In past decades, various metal/air batteries have been investigated; however, three major challenges still prevent Li/air batteries from practical application. The oxygen reduction and evolution both take place on the cathode and the effective and long-lasting bi functional cathodes have not been developed yet. In order to reduce the products of the discharge, such as Li2O2 and Li2O, effective catalysts have to be discovered. Lastly, Li2O2 or Li2O are not soluble in the non-aqueous electrolyte currently used by researchers. They will clog the pores of the cathodes and eventually seize the cell. Focusing on these issues, we have conducted our initial investigation on cathode architecture, catalyst, electrolyte and the performance of the Li/air cells developed in out lab. We will discuss our results and share our vision for the future of this technology.

Batteries That Charges On Air EEE Final Project Report Conclusion:

The lure of extremely high specific energy and specific capacity is the impetus for recent advanced research on Li-air batteries. In non aqueous electrolyte solutions, the specific capacity of the Li-air cell is limited by the precipitation of lithium oxides within the cathode and the solubility of oxygen in the electrolyte solution which affect the transport of oxygen within the interior of the air cathode.
