Construction of Co3O4 three-dimensional mesoporous framework structures from zeolitic imidazolate framework-67 with enhanced lithium storage properties
We demonstrate a general method for the preparation of a series of 3D alkali metal vanadate aerogels, including NaV3O8, NaV6O15, and K0.25V2O5. The resulting aerogels exhibit excellent Li+ storage properties in terms of high specific capacity, good rate capability, and outstanding cyclic stability as cathodes for LIBs.
3D interconnected Nicore–NiOshell electrodes are simple to realize and scalable and provide superior lithium storage properties. Could this be the ideal configuration for microbattery applications?
Novel mesoporous three-dimensional GeO2 was successfully synthesized by a facile one-step synthesis method followed by mixing with graphene using a spray drying process.
In this study, core–shell ZnCo2O4 spheres composed by nanoparticles were prepared via constructing a novel zeolitic imidazolate framework (ZIF) sphere with the assistance of citric acid.
