Improved Energy Efficiency of Lithium-Air Batteries by using Alloy Based Anode and Photocatalyst Loading Cathode
Abstract
The development of high energy density batteries has been rapidly advanced by the increasing
energy demand of the modern world. The lithium-air batteries have great interest due to their having the highest
energy density compared to the other battery technologies. However, the large implementation of lithium-air
batteries is hindered using metallic Li anode, leading to low coulombic efficiency, low energy efficiency and
safety problems. In this study, to improve the performances of these batteries, we designed the lithium-air
battery by integrating the Li-Si based alloy anode and photo-catalyst loading porous carbon cathode. The results
show that the designed lithium-air battery has low over potential through the extended cycling stability. The
working voltage of the cell is below 2.5 V. This study indicates that the developed the lithium-air battery with
higher coulombic efficiency and lower polarization values is the alternatives to the conventional lithium-air
batteries, which comprise metallic Li anode and carbon-based cathode.
