The development of electrode materials with superior cycling stability is currently receiving intensive research for next‐generation portable electronic equipment. Herein, a novel 3D hierarchical architecture composed of TiO₂/epitaxially aligned MoS₂–carbon coupled interface nanosheets is reported for boosting sodium‐ion storage and lithium–sulfur batteries, in which the MoS₂ nanosheets are epitaxially aligned grown on the surface of carbon nanosheets through a simple calculation conversion process. The resulting hybrid demonstrates ultralong‐life performance for sodium‐ion storage and lithium–sulfur batteries, owing to synergistic effects among the stable TiO₂ nanowires, the high‐conductivity carbon nanosheets, and the vertical MoS₂ nanostructure. Even at a high current density of 8 A g⁻¹, the capacity can be maintained at 169 mA h g⁻¹ after 15 000 cycles, one of the highest values for TiO₂‐based electrodes. Moreover, such peculiar sheet‐on‐sheet structure also brings benefits for lithium–sulfur batteries, providing an effective physical shield against polysulfide shuttling and chemical adsorption of polysulfides, with a low fading rate (0.039% per cycle over 1500 cycles). The present work highlights that this rationally designed hybrid nanoarchitecture is an effective strategy to boost the stability of electrochemical energy storage.
