Electrospun-nanofibrous Redox-active separator for enhancing the capacity of Lithium-ion batteries

Separator is a key component of lithium-ion battery (LIB), and a redox-active separator can enhance the capacity of LIB by participating in battery reactions. This paper reports a redox-active separator based on Fe(CN)6 4- doped polypyrrole (PPy) composite nanofibers fabricated by electrospinning and in-situ polymerization. The separator is composed of one layer of Polyacrylonitrile (PAN)@doped-PPy core–shell structured nanofibers and another …
