Cationic Surfactant-Type Electrolyte Additive Enables Three-Dimensional Dendrite-Free Zinc Anode for Stable Zinc-Ion Batteries
Sun Yat-sen University · Guangdong University of Technology
Abstract
Zn metal has been considered as a promising anode material for rechargeable aqueous metal-ion batteries. However, the propensity of dendrite growth during plating restricts its practical applications. Herein we propose an effective, low-cost, and nontoxic electrolyte additive, tetrabutylammonium sulfate (TBA2SO4), as the first example of a cationic surfactant-type electrolyte additive in Zn-ion batteries, which can induce the uniform Zn deposition in both electrode preparation and the battery charge/discharge process. Electrochemical characterizations, in situ optical microscopy observation, along with density functional theory (DFT) calculations reveal the unique zincophobic repulsion mechanism, which results…
