Co‐Crosslinked Water‐Soluble Biopolymers as a Binder for High‐Voltage LiNi 0.5 Mn 1.5 O 4 |Graphite Lithium‐Ion Full Cells

Autor: Fanglin Wu, Arefeh Kazzazi, Peter Axmann, Margret Wohlfahrt-Mehrens, Stefano Passerini, Hyeongseon Choi, Dominic Bresser, Matthias Kuenzel

Publikováno v: Chemsuschem

The use of water‐soluble, abundant biopolymers as binders for lithium‐ion positive electrodes is explored because it represents a great step forward towards environmentally benign battery processing. However, to date, most studies that employ, fo
