The depletion of fossil fuels, the rapid evolution of the global economy and the high standard of living make it necessary to investigate new energy storage systems to meet the needs of the world population.
Nagore Ortiz Vitoriano, Ikerbasque researcher at CIC energiGUNE, has just published a review in the prestigious ChemsusChem in which an overview of graphene-based cathodes is presented, through the reduction of oxygen and evolution reactions in batteries of Lithium (Li) and Sodium (Na) with Oxygen (O). Metallic (Li, Na) oxygen batteries are created because they are promising alternatives to widely used lithium ion batteries due to their high theoretical energy density that is closer to the behavior of gasoline.
Although significant progress has been made in recent years, there are still some challenges that must be overcome to achieve the final commercialization of this technology. Graphene, a lamellar structure made up of carbon atoms, has special characteristics and is used as a cathode in these batteries. In this review, a broad view of the literature in this area is presented and analyzed in order to guide future research.
