Zusammenfassung:	© 2022 Wiley-VCH GmbH. Transition metal dichalcogenides (TMDs) are regarded as promising cathode materials for zinc-ion storage owing to their large interlayer spacings. However, their capabilities are still limited by sluggish kinetics and inferior conductivities. In this study, a facile one-pot solvothermal method is exploited to vertically plant piezoelectric 1T MoSe2 nanoflowers on carbon cloth (CC) to fabricate crystallographically textured electrodes. The self-built-in electric field owing to the intrinsic piezoelectricity during the intercalation/deintercalation processes can serve as an additional piezo-electrochemical coupling accelerator to enhance the migration of Zn2+ . Moreover, the expanded interlayer distance (9-10 Å), overall high hydrophilicity, and conductivity of the 1T phase MoSe2 also promoted the kinetics. These advantages endow the tailored 1T MoSe2 /CC nanopiezocomposite with feasible Zn2+ diffusion and desirable electrochemical performances at room and low temperatures. Moreover, 1T MoSe2 /CC-based quasi-solid-state zinc-ion batteries are constructed to evaluate the potential of the proposed material in low-temperature flexible energy storage devices. This work expounds the positive effect of intrinsic piezoelectricity of TMDs on Zn2+ migration and further explores the availabilities of TMDs in low-temperature wearable energy-storage devices
