Abstract To overcome the limitations of commercializing lithium‐ion batteries (LIBs), a one‐step feasible route is reported to prepare hybrid matrix molybdenum oxides (MoO 3‐x , x = 0 and 1) thin film anode. In this direction, electrical conductivity barriers MoO 3 dielectric are by reinforcing conductive 2 via chemical vapor deposition (CVD) route. The intermixed array nanograins nanoflakes grown over stainless‐steel (SS) foil delivers maximum gravimetric capacitance 281 F g −1 specific capacity 348 mAh at 1 A . synergistic integration metal facilitates multiple valencies, interfacial structural stability, abundant ion transport channels achieve wider voltage window 3.50 V. Subsequently, prepared Li||MoO ‐MoO @SS configuration possesses electric double‐layer pseudocapacitive energy storage leading remarkable 77.78 Wh kg excellent power 13.75 kW high‐rate tests for continuous 1200 charge–discharge cycles disclose retention ≈88% ≈100% Coulombic efficiency on 2‐fold enlargement current density. longer lifespan higher rate nanohybrid anode owing reversible lithiation/delithiation further recommend its candidacy in developing LIBs next‐generation portable electronics.
