Elucidating the aluminum storage mechanism in cobalt sulfide cathode materials for advanced batteries
Jun Zhang
Abstract
Rechargeable aluminum-ion batteries (AIBs), as novel energy storage systems featuring low-cost, high-energy density, and superior safety, demonstrate promising potential as a next-generation battery technology. However, the lack of high-performance cathode materials remains a critical barrier to practical implementation. In this study, highly crystalline cobalt sulfide (Co9S8) nanoparticles were synthesized using a one-step hydrothermal method and systematically evaluated their...
