Population-Weighted First-Shell Coordination States Rationalize Li + and Na + Mobility in PEO and PEC Polymer Electrolytes
Understanding the molecular origin of the distinct transport behavior of Li+ and Na+ in polymer electrolytes remains a central challenge for next-generation energy-storage materials. Here, cation transport in poly(ethylene oxide) (PEO) and poly(ethylene carbonate) (PEC) electrolytes is investigated using atomistic mo...
