Summary: By analyzing experimental spectra and molecular simulation results, a direct link between tetrahedral entropy and the freezing behavior of water in Zn2+-based electrolytes is reported. Higher tetrahedral entropy leads to a lower freezing point, and the freezing temperature is directly related to the entropy value. Through tailoring the entropy of water, an ultralow temperature aqueous polyaniline|Zn battery is developed, exhibiting high capacity (74.17 mAh g(-1)) at -80 degrees C and excellent stability and frost resistance.

Summary: This study reports a method for depositing (002)-textured and compact Zn on textureless substrates (commercial Zn, Cu, and Ti foils) at a medium-high galvanostatic current density. The electrodeposition of fine horizontal (002) nuclei and the advantages of (002)-orientated nuclei contribute to the suppressed hydrogen evolution and prolonged cycling life of Zn in this study. The resulting freestanding (002)-textured Zn film achieves a high cumulative capacity under a current density of 10 mA cm(-2) and a high depth of discharge (DOD) of 45.5%. The study provides important insights for the development of long-life Zn metal batteries.

Summary: In this study, a polycation additive, polydiallyl dimethylammonium chloride (PDD), is introduced to achieve long-term and highly reversible Zn plating/stripping. The PDD can regulate the electric fields of electrolyte and Zn/electrolyte interface to improve Zn2+ migration behaviors and guide dominant Zn (002) deposition. Moreover, PDD creates a positive charge-rich protective outer layer and a N-rich hybrid inner layer to enhance the Zn2+ desolvation and prevent direct water contact with the Zn anode, resulting in improved reversibility and long-term stability of Zn anodes.

Instead of the traditional bulk solvation mechanism, this study reveals that the structure of SEI is mainly influenced by electric double layer (EDL) adsorption. By manipulating the EDL adsorption and Zn2+ solvation using ether additives, a layer-structured SEI with high rigidity and toughness is formed, leading to improved performance of the zinc metal electrodes.

Summary: In this study, a charge-transfer complex electrolyte additive, 7,7,8,8-tetracyanoquinodimethane (TCNQ), with high affinity for zinc was used to form a dense and robust interfacial complex layer on the zinc anode, suppressing the activity of H(2)O. The complex layer enabled the formation of a Zn-Zn-(TCNQ)(2) Ohmic contact interface, facilitating rapid ion/electron transport, improving electric field distribution, and preventing direct contact between active H2O and the zinc anode, resulting in a dendrite-free zinc anode and efficient zinc plating/stripping kinetics. As a result, the Zn||Zn symmetrical cell exhibited high plating/stripping reversibility for over 1000 hours at 20 mA cm(-2) and 5 mA h cm(-2), and a high depth of discharge of 43%. Furthermore, the Zn||MnO2 full cell demonstrated a high capacity of 143.3 mA h g(-1) at 2000 mA g(-1) even after 4000 cycles, with a capacity retention of 94.7% after returning to 100 mA g(-1).

Summary: By using a 100 mM xylitol additive, the plating/stripping processes in Zn-ion batteries can achieve high reversibility. The xylitol molecules not only inhibit the hydrogen evolution reaction, but also accelerate the migration of cations through the expelling of active H2O molecules and weakening of electrostatic interactions. Additionally, the preferential adsorption of xylitol molecules on the Zn surface forms a shielding buffer layer, which hinders the sedimentation and diffusion of Zn2+ ions.

Summary: Dendrite formation is a major obstacle to the development of zinc ion batteries. Increasing the nucleation overpotential is important for achieving uniform deposition of metal ions, but this strategy has not received enough attention from researchers. In this study, the authors propose using a complexing agent, sodium L-tartrate (Na-L), to enhance the thermodynamic nucleation overpotential of Zn deposition. Na-L replaces some of the water molecules in the solvation sheath of Zn2+, increasing de-solvation energy. In addition, Na+ preferentially absorbs onto the surface of the Zn anode to inhibit Zn2+ aggregation. This increases the overpotential of Zn deposition from 32.2 to 45.1 mV. By using Na-L, the Zn-Zn cell achieves 80% Zn utilization at an areal capacity of 20 mAh cm(-2). The Zn-LiMn2O4 full cell with Na-L additive also exhibits improved stability compared to the blank electrolyte. This study provides valuable insights into controlling nucleation overpotential for achieving homogeneous Zn deposition.
