Summary: Electrolyte environments, including cations, anions, and solvents, play a critical role in the performance of battery cathodes. However, most research has focused on the interaction between cations and cathode materials, neglecting the correlation between anions and cathodes. This study systematically investigates how anions influence the coulombic efficiency (CE) of zinc battery cathodes, demonstrating that the electronic properties of anions can tune conversion or intercalation reactions, resulting in significant differences in CE.

Summary: In this study, a novel deep eutectic solvent electrolyte containing choline chloride (ChCl) and ZnCl2 was developed to improve the cycle life of aqueous Zn metal batteries (ZMBs). ChCl coordinates with Zn2+ to reduce water activity and mitigate cathode dissolution and zinc dendrite formation. With this electrolyte, the vanadium oxide cathode maintains a high capacity over 100 cycles at a harsh current density, and the Zn metal anode can be cycled for a longer time without dendrite formation. The results highlight the importance of ChCl as a co-solvent for ZnCl2 in facilitating high performance of ZMBs.

Summary: The topological optimization of prelithiated SiO materials was shown to effectively improve both the initial coulombic efficiency (ICE) and capacity retention. By using laser-assisted atom probe tomography and other techniques, two exothermic reactions related to microstructural evolution were identified as key factors in optimizing the domain size and topological arrangements of the Si active phase and Li2SiO3 buffer phase in prelithiated SiO materials. The optimized prelithiated SiO, heat-treated at 650 degrees C, demonstrated higher capacity retention and lower thickness changes after 300 cycles, along with high ICE and reversible capacity.

Summary: The directly synthesized MnO2 using ambient temperature aqueous solution deposition strategy shows great application prospects as the cathode material for aqueous zinc-ion batteries. However, MnO2 suffers from poor energy density and capacity fading. To address this issue, researchers developed a simple one-step deposition method using ambient temperature aqueous solutions to synthesize MnSe2, which exhibits superior capacity and cycling stability. The MnSe2 cathode achieved a high capacity of 452.4 mAh g(-1) at a low current density of 0.1 A g(-1) and an excellent rate capability of 242.7 mAh g(-1) at 2.0 A g(-1). After 2000 cycles, the Zn/MnSe2 battery maintained a specific capacity of over 231.5 mAh g(-1) and a cycling retention of 86.3%. This work provides a new approach to develop simple, high-capacity, and long-life aqueous zinc-ion batteries.
