Article Synopsis
- Regulating the electrical double layer (EDL) can improve the stability of zinc (Zn) metal anodes, but individual additives often fall short in effectiveness.
- A new multi-component EDL was created by using dibenzenesulfonimide (BBI) and LaCl additives, enhancing charge shielding on the Zn surface and allowing for better performance.
- This innovative approach led to a remarkable 99.5% reversibility in zinc anodes and demonstrated a stable cycling life of 100 cycles in Zn|MnO pouch cells at a low N/P ratio.
Aqueous Zn-S batteries (AZSBs) have garnered increasing attention in the energy storage field owing to their high capacity, energy density, and cost effectiveness. Nevertheless, sulfur (S) cathodes face challenges, primarily stemming from sluggish reaction kinetics and the formation of an irreversible byproduct (SO) during the charge, hindering the progress of AZSBs. Herein, Te-S bonds within S-based cathodes were introduced to enhance electron and ion transport and facilitate the conversion reaction from zinc sulfide (ZnS) to S.

- Imaging through the wavy water-air interface faces challenges like geometric distortion and motion blur, making it hard to accurately identify monitored objects.
- A new reconstruction scheme is introduced, combining lucky-patch search and image registration techniques to improve image recovery accuracy and computational efficiency.
- The method includes creating a high-quality reference frame, using an iterative registration algorithm enhanced with optimization strategies to correct distortions, and refining the final frames to reduce remaining noise, leading to better image sharpness and contrast compared to existing methods.
