Published: January 2023

A PEO-based SPE modified by TPPi has a wide electrochemical window and exhibits excellent electrochemical performance. O and P, with lone pairs of electrons in TPPi, are easily chelated with the Ni with empty orbitals in LiNiCoMnO, which inhibits Ni/Li cationic disordering and weakens the oxidation of PEO-based electrolytes by Ni.
