Modification of Carboxymethyl Chitosan as Water Soluble Binder for Lithium Iron Phosphate Cathode in Lithium-ion Batteries

Abstract

Carboxymethyl chitosan （C-CTS） was modified in two different methods as water soluble binder for LiFePO4 （LFP） cathode： （1） blending C-CTS with polyethylene oxide （PEG） to prepare the composite binder （C-CTS/PEG）, （2） using trimethylolpropane tris（2-meth
