Interlaced CoOx Nanosheets Composited with Reduced Graphene Oxide and Carbonized Bacterial Cellulose as Anode Materials for Lithium‐ion Batteries

Abstract

AbstractConstructing peculiar carbon‐based networks built from hybrid structures has been considered as an effective approach to establish a superior scaffold for immobilization of nanoparticles. Herein, we demonstrate a facile and green approach to prepare cobalt oxides (CoOx)‐based anode, which is realized by rationally exploiting unique properties of carbonized bacterial cellulose (CBC) and graphene (GN). The unique configuration of GN/CoOx/CBC composite fully enables utilization of the synergistic effects from both three‐dimensional nanofibrous network and two‐dimensional “flexible confinement” function. Benefiting from their intriguing structural features, the synthesized composite is directly used as electrode for lithium‐ion batteries (LIBs), and achieves superior flexibility and reliability, enhanced energy/power density and outstanding cycling stability.
