Abstract
Energy storage is a cornerstone of modern electronics, yet most batteries and supercapacitors rely on materials that are scarce, toxic, or persistent in the environment. Cellulose nanofibres (CNF) – derived from wood pulp and one of the most abundant biopolymers on Earth – offer a compelling alternative. Mechanically robust, chemically tuneable, and fully biodegradable, CNF can serve simultaneously as electrode host, separator, and structural matrix in energy devices.
This talk traces a research arc from roll-to-roll printed CNF-based supercapacitors and batteries developed at scale with RISE Norrköping, to cellulose-based cathodes in bioresorbable magnesium batteries designed for ingestible and implantable electronics.
Together, these works demonstrate that CNF is not a novelty substrate but a serious materials platform – one capable of powering devices that are safe for the body and kind to the planet.
