Carboxymethyl Cellulose As The Binder For The Lithium-Sulfur Batteries

Abstract

Demand for the high energy density batteries significantly increased along with the rapid development of new power source depending technologies. While these technologies are rapidly evolving, the battery industry is lagging behind unable to meet the demand. As a prospective successor to the existing li-ion battery technology, can be the high-capacity lithium-sulfur battery system (Li-S). The most commonly used composition of the positive electrode material of Li-S batteries is a mixture of sulfur, carbon and PVDF1 binder mixed in NMP2 solvent, which is (according to the WHO3) slightly toxic. The article deals with a replacing PVDF with organic non-toxic water-soluble binder.
