The purpose of the present talk is twofold. On one side, we report on the current progress we are making in a project to support the development of Li-ion batteries in Argentina. On the other side, we report on the most recent advances made in the world using state-of-the-art quantum mechanical calculations to understand the phenomena that are challenging the development of Li-air batteries.
Concerning the first point, some of the items to be addressed are:
-Technical problems.
-Financial problems.
-Potential market of the products. Limitations in the production.
Concerning the second point, we will address the following items from a theoretical viewpoint:
- Discussion of the electrochemical reactions at the oxygen electrode of an aprotic Li-air battery from a DFT view.
-Estimation of the free energies of the different intermediates that arise in these reactions.
-Influence of oxygen pressure on the previous item.
- Role of electrocatalysts in reducing overpotentials and enhancing reaction rates.
