摘要

In this study, ultra-range cerium oxide (CeO2) nanoparticles (NPs)/manganese oxide (Mn3O4) nanosquares (NSs) nanocomposite (NC) is used first time as a cathode material for Lithium ion (Li-ion) batteries. The CeO2 NPs exhibit a discharge capacity of 247.1 mAh g-1, Mn3O4 NSs reach 346 mAh g-1, while CeO2/Mn3O4 NC material achieves 539.8 mAh g-1 at a current density of 0.5 A g-1. The CeO2/Mn3O4 NC material demonstrates impressive capacity retention (90.3 %) at 100 cycles and columbic efficiency (82 %) after 300 continuous cycles, respectively. This battery represents a novel safe open system designed to operate at room temperature. In this configuration, graphite foil serves as the cathode substrate, while aluminum (Al) foil is utilized as the anode substrate. The CeO2/Mn3O4 NC goal is to advance rechargeable battery technology, focusing on high performance, cost-efficiency, environmental sustainability and demonstrating promising potential for next-generation high-energy storage cathode electrodes in battery applications.
