PEO composite solid polymer electrolytes with the synergistic effect of cryogenic engineering and trace BP nanosheets for nearly room temperature and 4 V class all-solid-state lithium batteries

Abstract

A novel PEO-based SPE with a synergistic effect of black phosphorus (BP) nanosheets and a cryogenic method, which can combine the advantages of the fast Li+ pathways of BP nanosheets and the low PEO crystallization of cryogenic method.
