3D shuttle V₂O₅ preparation of porous nanomaterials and lithium storage properties

V₂O₅, as a potential cathode material for lithium-ion batteries (LIBs), is limited by poor activity and structural stability. Herein, a series of 3D shuttle V₂O₅ materials are obtained by a simple solvothermal method combined with subsequent calcination. When the calcination temperature was set to 600°C, the obtained V₂O₅ porous material (V-MOFs-600) had the largest specific surface area and pore volume, which conferred more Li⁺ embedding sites and thus accelerated Li+ embedding/de-embedding. Based on this, paired with a lithium anode, the V-MOFs-600 cathode exhibits excellent lithium storage performance parameters of 162.1 mAh·g^-1 at 1A·g^-1 and 78.3% capacity retention after 200 cycles. These results indicate that the 3D shuttle V₂O₅ porous nanoelectrode materials assembled from particles are highly promising as long-life, high-rate cathode materials for next-generation LIBs.
