Other Advanced Batteries

Our research group is involved in research activities related to development of materials for application in other advanced batteries such as: 

Metal-air batteries

 The bottleneck in advancement of metal-air batteries is the development of efficient oxygen electrodes to speed up intrinsically sluggish oxygen reduction (ORR) and evolution (OER) reactions. In our group, we have been done extensive efforts to develop highly-efficient and low-cost, non-precious oxygen catalysts like oxides, sulfides and metal-free electrocatalysts. Some of these materials have been employed as bifunctional catalysts to fabricate gas diffusion electrodes, demonstrating excellent properties as air-cathodes for rechargeable Zn-air batteries.

Zn-MnO2 batteries

5 other advanced batteries 4Primary Zn-Mn batteries are one of the cheapest chemistries in energy storage technologies. Recently, the limited reversibility of this technology has been demonstrated. In our group we are interested in overcoming the present limitation associated to rechargeability by following several strategies i) novel designs involving flow electrolytes, ii) developing advanced electrolytes, iii) stablishing “smart charging protocols” and iv) implementing semi-solid MnO2 electrodes.
