<p>Surfactants possess unique properties in bulk solutions and at interfaces, naturally forming self-assembled structures. Herein, cetyltrimethylammonium trifluoroacetate (CTATFA) was incorporated into aqueous electrolytes as a cationic surfactant to enhance their ionic conductivity and electrochemical stability. The presence of CTATFA widened the electrochemical stability windows of both Li-based and Zn-based electrolytes. The Zn-based electrolyte exhibited high ionic conductivity and low viscosity in the bulk solution. In a Zn symmetric cell, the electrolyte containing 1 M Zn(TFA)<sub>2</sub>-0.5 M CTATFA demonstrated excellent Zn plating/stripping reversibility for over 800 h at 1 mAh cm<sup>−2</sup> and 1 mA cm<sup>−2</sup>. A Zn-Cu cell with 1 M Zn(TFA)<sub>2</sub>-0.5 M CTATFA exhibited excellent reversibility, achieving over 300 plating/stripping cycles at 5 mA cm<sup>−2</sup> and 5 mAh cm<sup>−2</sup>. The Zn/MnO<sub>2</sub> cell using the Zn-based electrolyte also demonstrated a specific capacity of 105 mAh g<sup>−1</sup> over 750 cycles at a current density of 0.5 A g<sup>−1</sup>. This study provides insight into the design of high-performance aqueous electrolytes based on the self-assembly and surface adsorption of cationic surfactants.</p>

ACS Applied Polymer Materials 7 ( 5 ) 3296 - 3308 2025.2
Language:English Publishing type:Research paper (scientific journal) Publisher:American Chemical Society (ACS) Joint Work
Lithium metal batteries (LMBs) offer tremendous potential due to their high energy density, but practical applications are limited by challenges such as dendrite formation, safety risks, and interfacial instability. This study introduces a composite gel polymer electrolyte (GPE) that systematically integrates sulfolane-based highly concentrated electrolytes (HCEs) with two-dimensional hexagonal boron nitride nanosheets (BNNs). Through advanced experimental characterizations, electrochemical measurements, and theoretical calculations, the composite GPE is shown to achieve enhanced mechanical strength, thermal stability, and superior Li ion transport properties. The incorporation of BNNs not only reinforces the electrolyte matrix but also facilitates selective Li ion transport via strong interactions between Li ions and the filler, as validated by theoretical studies. The optimized composite GPE demonstrates outstanding electrochemical performance, achieving a high ionic conductivity of 0.7 × 10–3 S cm–1 at 30 °C and stable cycling for over 1000 h in Li/Li symmetric cells and more than 300 cycles in Li/LiFePO4 cells, along with excellent rate capabilities. This work provides a comprehensive strategy for addressing the critical limitations of LMBs and establishes a robust framework for developing next-generation high-performance solid-state battery systems.
