A Biobased Composite Gel Polymer Electrolyte with Functions of Lithium Dendrites Suppressing and Manganese Ions Trapping

Lithium (Li) dendrites in Li anodes, and dissolution and migration of manganese (Mn) ions in LiMn 2 O 4 (LMO) cathodes, have hampered these extraordinary electrode materials from being efficiently applied in high performance Li batteries. Here, a novel, bifunctional, biobased composite gel polymer electrolyte (c‐GPE) is created to simultaneously deal with the two critical issues. The skeleton of c‐GPE is constructed from a sandwich structure...
