High Lithium Ionic Mobility in Mo6S8 Chevrel Phase Cathodes
In addition, there are many on-going efforts to discover improved electrolytes for Mg batteries. It has been recently demonstrated that using an electrolyte with a concentrated lithium salt could benetit the thermodynamic and kinetic in a lithium-sulfur cell . Here, we report the experimental and computational calculation results to explain unusually high ionic mobility of lithium in Mo6S8 chevrel phase cathode materials. When a concentrated lithium salt of 0.5M LiCl is added to the conventional APC electrolytes, almost full theoretical capacity can be achieved at room temperature in Mo6S8 Chevrel phase cathode materials at very high C-rates up to 20, 30C.
