Electrolyte‐free cathode design for solid‐state batteries demonstrated with bifunctional Li2VCl4

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
The “electrolyte‐free” cathode design is demonstrated by utilizing the ion‐conducting active material Li2VCl4. This design is exclusively viable within all‐solid‐state battery configurations, where both active materials and electrolytes exist in the solid state.

Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

open access: yesBatteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)
