Herein, l-tartaric acid (L-TA) is made to self-assemble on a preconstructed V2O5/V3O7·H2O (V2V3) heterointerface, forming a hydrogen bond interfacial layer (HB-V2V3). The hydrogen-bond network reinforces interfacial cohesion and induces oriented dipoles, which cooperate with the heterojunction’s built-in electric field to enhance electronic coupling and accelerate Zn2+ transport.

Functioning as a noninvasive and compliant molecular “sheath”, it regulates the local chemical environment while preserving the host lattice. As a result, HB-V2V3 delivers a reversible capacity of 464.53 mAh g-1 at 0.1 A g-1 within 0.2–1.6 V and exhibits outstanding durability, retaining 95.5% after 500 cycles at 2.0 A g-1 and 93.1% after 2200 cycles at 5.0 A g-1.
