Backbone-Mediated Coordination-Environment Reshaping in Gel Polymer Electrolytes for High-Voltage Lithium Metal Batteries.
Conventional linear polyether electrolytes feature abundant ether-oxygen sites that dominate the primary Li+ solvation shell, limiting anion participation and undermining ion transport and high-voltage stability. A backbone-mediated coordination-environment reshaping strategy is proposed by incorporating diglycidyl 1,2...
