Enhancing lithium-ion batteries performance via electron-beam irradiation strategies: A case study of graphene aerogels loaded with SnO2 quantum dots

Ultrathin cross-stacked graphene aerogels loaded with SnO2 quantum dots has been successfully fabricated by a simple hydrothermal method with graphene oxide and Sn as the precursors. The composites were intentionally irradiated by electron-beam with different irradiation dose to modify its surface and structure. It was found that the SnO2-QDs/Gas-HCl composite irradiated at 280 kGy showed an excellent cycling and outstanding rate performances.467
