Enhancing aluminium-ion battery performance with carbon xerogel cathodes Almodóvar Losada, Paloma Rey Raap, Natalia Flores López, Samanta Sotillo Buzarra, Belén Santos, Lara Tinoco Rivas, Miguel Ramírez Castellanos, Julio Álvarez Serrano, Inmaculada López García, María Luisa Cameán, Ignacio Arenillas, Ana Chacón, Joaquín García, Ana B. 546 Ciencias 23 Química This study presents groundbreaking results in the field of rechargeable aluminium-ion batteries, achieving stable capacities exceeding 300 mAh g-1 for more than 300 cycles. The key to this achievement lies in the utilization of tailor-made carbon materials and a urea-AlCl3-based electrolyte. The article investigates the optimal physicochemical properties of the active material necessary for effective electrodes for these aluminium-ion batteries. This investigation employs a wide range of materials characterization techniques (XRD, SEM-EDX, N2 adsorption-desorption isotherms, Hg porosimetry, XPS, FTIR, Raman and TEM-EDX) and electrochemical performance analyses to delve into the subject. These findings represent a significant improvement in the capacity of aluminium-ion batteries, bringing us closer to their implementation and commercialization. This achievement is attributed to the utilization of readily available, cost-effective, and non-corrosive materials. The ability to customize carbon xerogels and the use of the urea-AlCl3 electrolyte offer promising avenues for the practical implementation of these advanced battery technologies, leading to further enhancements in their performance and widespread adoption in various applications.
