Pyrolyzed Bacterial Cellulose: A Versatile Support for Lithium Ion Battery Anode Materials

Abstract

A scalable, low-cost and environmentally benign strategy is developed for the facile construction of a unique kind of three-dimensional porous electrode architecture for high-performance lithium ion batteries. The methodology is based on the employment of pyrolyzed bacterial cellulose as a new three-dimensional porous scaffold to support various nanostructured active electrode materials, such as SnO2 and Ge.
