Tailoring the Electrochemical Performance of SnO2‐Based Anodes for Li‐Ion Batteries: Effect of Morphology and Composite Matrix

Year: 2025

Type: article

Abstract: Three different composite anodes, based on SnO2, are investigated as potential anode materials for lithium‐ion batteries. Three different strategies have been employed to stabilize SnO2 upon cycling, i.e., i) use of an inorganic matrix (TiO2), ii) use of an amorphous carbon matrix, and iii) use of SnO2 with a tailored morphology (nanorod) and a carbon coating. Specific capacities, ranging from 700 up to 1000 mAh g−1, are obtained during galvanostatic cycles with high‐capacity retentions. Furthermore, this work sheds light on the interfacial and transport properties of such electrode materials, given by cyclic voltammetry at different scan rates, galvanostatic intermittent titration technique, and electrochemical impedance spectroscopy.
