The increasing deployment of renewable energy sources requires the development of increasingly efficient and sustainable storage systems. In this context, lithium-air batteries (LABs) represent one of the most promising technologies due to their exceptionally high theoretical energy density, which can reach values comparable to those of fossil fuels and significantly superior to current lithium-ion batteries. However, their practical application is still limited by numerous challenges, including poor cyclability, the accumulation of discharge products within the cathode, high charging overpotential, and the requirement to operate with lean electrolyte conditions to achieve genuinely competitive energy densities. This thesis work is aimed at developing an innovative cathode for non-aqueous lithium-air batteries, designed to achieve practically relevant capacities and improve overall system performance.
