Lithium-Ion

Tailoring Polymer Electrolyte Solvation for 600 Wh kg 1 Lithium Batteries Electrolyte Feature: the polymer electrolyte creates an anion-derived F-rich CEI/SEI to protect the lithium-rich metal oxide cathode by suppressing surface oxygen escape, structural transitions, and electrolyte decomposition Electrochemical Performance: this quasi-solid-state polymer demonstrates a reversible high-areal-capacity cycling in pouch cells. The pouch cells exhibit an energy density of 604 Wh kg1 and excellent safety under a nail penetration at a fully charged condition

ELECTROCHEMICAL PERFORMANCE

FBASED ELECTROLYTE

The strong coordination between Li+ and ether oxygen generates anion-deficient solvation, whereas the poor oxidation stability of PE polymer electrolytes causes interfacial decomposition
