Separating Hydrogen Evolution From Electroplating in Zn Metal Batteries Using Scanning Electrochemical Microscopy

Advanced Energy Materials, EarlyView.
Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

Reconstructing Solvation Structure via Strongly Nucleophilic Anions for High‐Rate and Low‐Temperature Graphite||LFP Pouch Cells in PC‐Based Electrolyte

Advanced Energy Materials, EarlyView.
A nucleophilic‐anion‐regulated solvation strategy is developed for Propylene carbonate (PC)‐based electrolytes, where NO3−${\mathrm{NO}}_3^ - $ preferentially enters the Li+ solvation sheath and replaces coordinated PC molecules without sacrificing ionic conductivity.
