Synergistic interaction between amphiphilic ion additive groups for stable long-life zinc ion batteries

Enhanced electrostatic shielding effect through incorporation of trace amounts of highly chelating anions for establishing a more stable electric double layer

“…These shifts are attributed to the polarization and phase transition of the δ-MnO 2 cathode. 46 The fitted b -values are shown in Fig. 5b and c according to the equation i = ab , 47,48 and the b -values with the addition of IDHA are 0.614 (peak 1) and 0.723 (peak 2), which means that the capacity is mainly determined by the pseudocapacitive process.…”

Amphiphilic electrolyte additive as an ion-flow stabilizer enables superb zinc metal batteries

“…Besides, compared to non-ionic additives, ionic additives can enhance the preferential adsorption on the interface due to electrostatic interactions, promoting the improvement of the interfacial ion transfer. 33,34 Furthermore, the regulation of the solution structure can further enhance ion transport dynamics, contributing to the realization of high-rate zinc anodes. Hence, the adoption of amphiphilic small molecule ionic additives for dual regulation of the solution network structure and interface characteristics could be a potential strategy for achieving dual enhancement of both the charge transfer kinetics and the stability of the zinc anode, presenting profound insights and a promising path into the development of aqueous energy storage.…”
