The sluggish diffusion kinetics of divalent Zn²⁺ in cathode and the limited availability of active material have seriously hindered the practical application of aqueous zinc ion batteries (AZIBs). Herein, multi-walled carbon nanotubes modified by amorphous carbon layer successfully compounded with MoS₂ (MWCNTs@a-C@MoS₂) are designed as the cathode for AZIBs. Benefiting from the large number of oxygenous groups on the loose surface of amorphous carbon, MoS₂ can uniformly nucleate and grow on the MWCNTs, thus avoiding the agglomeration of MoS₂ and improving the utilization of active materials. Therefore, this nanocomposite exhibits long-term cycling stability (78% capacity retention after 1000 cycles at 5 A g^-1) and glorious high-rate capability (110 mAh g^-1 at 12 A g^-1). The electrochemical reaction kinetics of MWCNTs@a-C@MoS₂ electrode were investigated by galvanostatic intermittent titration (GITT), cyclic voltammetry (CV) measurements and molecular dynamics (MD) simulations, indicating its desirable pseudocapacitive behaviors and low Zn²⁺ diffusion energy barrier. By ex-situ characterizations, the Zn-intercalation mechanism of MWCNTs@a-C@MoS₂ was revealed. This electrode also exhibits stable performance in flexible quasi-solid-state AZIBs even under extreme bending conditions, demonstrating its practicality.
