A Bioconfined Synthesis Strategy of Sb2s3N-Doped Carbon Ribbons for Boosting Ultralong-Life Sodium Storage
Reducing the synthesis costs of electrode materials and improving their electrochemical performance remain key issues regarding the application of sodium-ion batteries (SIBs) in large-scale energy storage devices. Antimony sulfide (Sb2S3) is a promising anode material for SIBs because of its high theoretical capacity and low-cost. However, its poor electrical conductivity and volume expansion hinder its practical application. Aspergillus niger is an environmentally friendly, low-cost, and renewable fungus with a one-dimensional (1D) structure, it has high application value as a natural carbon source in energy storage materials. Herein, Sb2S3 composite N-doped carbon ribbons (Sb2S3@NCRs) are prepared using Aspergillus niger via the gas-phase sulfuration method. These Sb2S3@NCRs show excellent electrochemical performance as anode materials for SIBs. Using Na3V2(PO4)3 (NVP) as the counter electrode, here Sb2S3@NCRs//NVP is show to maintain a reversible specific capacity of 208.3 mAh·g–1 at 0.2 A·g-1 after 100 cycles. In addition, the step-wise transformation and alloying reactions of Sb2S3@NCRs were verify using in situ X-ray diffraction (XRD) tests. This simple and inexpensive synthesis method provides a new strategy for creating other low-cost large-scale energy storage materials
