This study introduces a novel approach to address the significant challenge of achieving highly reversible and dendrite-free zinc plating and stripping in aqueous zinc-ion batteries (AZIBs). The researchers designed a hierarchical carbon nanotube (CNT)-based host, functionalized with cetyltrimethylammonium cations (CTA⁺), which enables dynamic switchable repulsive shielding to regulate Zn plating. The CNT scaffold, known for its high flexibility and conductivity, facilitates the accommodation of continuous Zn plating. The entangled CTA⁺ cations form switchable repulsive shields that dynamically suppress Zn dendrite growth, ensuring uniform Zn plating within the CNT hosts. Density functional theory (DFT) calculations support the effectiveness of the electrostatic repulsive shield. Symmetric cells using this self-adaptive C-CNT host exhibit a stable cycling lifespan of over 6500 hours at 1 mA cm⁻² and achieve a cumulative capacity of 6000 mAh cm⁻² at 4 mA cm⁻². Full batteries, combining the C-CNT@Zn anode with MnO₂ cathode, demonstrate an 88% capacity retention after 2000 cycles at 2 A g⁻¹. This design offers a promising approach for enhancing the stability of AZIBs and other Zn-based aqueous energy storage systems.This study introduces a novel approach to address the significant challenge of achieving highly reversible and dendrite-free zinc plating and stripping in aqueous zinc-ion batteries (AZIBs).
