3D printing battery by using cellulose nanofiber as rheology modifier and carbon resource

Abstract

Sustainable energy plays a critical role in people's everyday life. Cellulose nanofiber (CNF) is an environmentally friendly material from wood pulp. Due to its sustainability, abundance, and biodegradability, CNF has been attracted broad attention in both academic and industry. Threedimensional (3D) printing is being one of the main advanced additive manufacturing because of its

3D printed cellulose based product applications

“…127 3D printed cellulose nanofiber can also act as a rheology modifier and a carbon source for battery cathodes and anodes. 128 Park et al 129 reported a 3D printable composite paste of nanosilver and cellulose having sturdy thixotropic rheology with a reliable conductivity of 1.19 Â 10 2 S cm À1 with a 1.9 vol% loading of silver nanowires. Rheological studies show the superior printing ability of the electrode paste aided by cellulose's thixotropic rheology.…”
