| description | One of the biggest challenges in the commercialization of tin dioxide (SnO<sub>2)</sub>-based lithium-ion battery (LIB) electrodes is the volume expansion of SnO<sub>2</sub> during the charge–discharge process. Additionally, the aggregation of SnO<sub>2</sub> also deteriorates the performance of anode materials. In this study, we prepared SnO<sub>2</sub> nanoflowers (NFs) using nanocrystalline cellulose (CNC) to improve the surface area, prevent the particle aggregation, and alleviate the change in volume of LIB anodes. Moreover, CNC served not only as the template for the synthesis of the SnO<sub>2</sub> NFs but also as a conductive material, after annealing the SnO<sub>2</sub> NFs at 800 °C to improve their electrochemical performance. The obtained CNC–SnO<sub>2</sub>NF composite was used as an active LIB electrode material and exhibited good cycling performance and a high initial reversible capacity of 891 mA h g<sup>−1</sup>, at a current density of 100 mA g<sup>−1</sup>. The composite anode could retain 30% of its initial capacity after 500 charge–discharge cycles. |
