Their suggested stability towards high-voltage cathode materials makes halide-based solid electrolytes currently an interesting class of ionic conductors for solid-state batteries. Especially the LiMn2O4 spinel active material is interest due to its slightly higher nominal voltage and more resilience overcharging compared LiCoO2 LiNixMnyCozO2 cathodes. Typically, a standard ratio electrolyte us...

Targeted improvement of the low efficiency of water oxidation during the oxygen evolution reaction (OER) is severely hindered by insufficient knowledge of the electrocatalytic mechanism on heterogeneous surfaces. We chose LiMn2 O4 as a model system for mechanistic investigations as it shares the cubane structure with the active site of photosystem II and the valence of Mn3.5+ with the dark-stab...

The development of high safety lithium-ion batteries (LIBs) is greatly impeded by the flammability and leakage concerns typical organic solvent-based electrolytes. As one alternative classes electrolytes, hydrogel electrolytes exhibit safety, flexibility, low cost, are benign to environment. However, narrow electrochemical stability window (ESW) restricts operating voltage battery cells. Here, ...
