Leaf‐Like V₂O₅ Nanosheets Fabricated by a Facile Green Approach as High Energy Cathode Material for Lithium‐Ion Batteries

Lithium-ion batteries (LIBs) have attracted considerable attention due to their wide applications, such as in portable electronic devices, implantable medical devices, and electric vehicles (EVs). [ 1 ] To meet the constantly increasing demands of upcoming electronic devices, new LIBs require substantial improvements in energy capacity, cycling stability, and rate capability of both the cathode and anode materials. [ 2,3 ] Among cathode materials for LIBs, orthorhombic vanadium pentoxide (V 2 O 5 ) the most stable form in the vanadium oxide family, has gained great interest due to its high energy density, low cost, abundant sources, and good safety properties.
