Calcination of the material under air yields highly crystalline, sponge-like V2O5 (gem-V2O5). In contrast, calcination of the amorphous tetrabutylammonium decavanadate allows isolation of a more agglomerated V2O5 consisting of very small crystallites (TBA-V2O5). Electrochemical analysis of the materials' performance as lithium-ion intercalation electrodes highlights the role of morphology in cathode performance. The large crystallites and long-range microstructure of the gem-V2O5 cathode deliver higher initial capacity and superior capacity retention than TBA-V2O5. The smaller crystallite size and higher surface area of TBA-V2O5 allow faster lithium insertion and superior rate performance to gem-V2O5.application/pdfeng(c) Wiley-VCH, 2023NanopartículesMaterials nanoestructuratsNanoparticlesNanostructured materialsinfo:eu-repo/semantics/article7298012023-02-23info:eu-repo/semantics/openAccess
