- Abstract
- In this study, a novel hybrid HoFeO3–Ho2O3 nanocomposite perovskite composite is synthesized via a simple coprecipitation method as a stable, high-capacity anode material for lithium-ion batteries. The structure and morphology of the material are characterized using advanced tools such as X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, all of which confirm the successful synthesis of nanocrystals with highly interconnected porous nanohallows. At 0.1 A g−1, the HoFeO3–Ho2O3 nanocomposite electrodes exhibit a stable reversible capacity of 787 mAh g−1 with a coulombic efficiency exceeding 99.5%. This capacity is nine times higher than that of Ho2O3 and 50% higher than that of Fe2O3 balance samples. This study provides new insights into the use of perovskite-structured materials with superior electrochemical performance for advanced lithium-ion storage. © 2021 John Wiley & Sons Ltd.
