Multimodal mesopore hierarchy in Li₃VO₄ boosts electrochemical anode performance of lithium-ion batteries

Enhanced anode performance has been achieved with nutshell shaped Li₃VO₄ having a cascading mesopore hierarchy in a hydrothermally synthesized nanocrystalline material. The remarkable enhancement in the capacity (357 mAh g⁻¹ at 0.1C) as compared to its solid-state counterpart (102 mAh g⁻¹ at 0.1C) is solely due to mesopore hierarchy comprising of three-dimensional interconnected channels that allows better electrolyte infiltration into the bulk of the active electrode material ensuing short Li-ion diffusion distances, increased charge-transfer reaction sites and fast Li-ion transport pathways in addition to three-dimensional ion diffusion.
