<p>ZnCo₂O₄ is considered a highly promising anode material for lithium-ion batteries (LIBs), attributed to its impressive capacity and excellent electrochemical characteristics. However, its practical application is constrained by significant volume expansion during repeated charge–discharge cycles, leading to structural instability and performance degradation over time. To address this challenge, a composite material consisting of reduced graphene oxide (rGO) coating the exterior of ZnCo₂O₄ microspheres (denoted as ZCO@r-3) was designed and synthesized in this study, making it an anode material with high cycling stability for LIBs. This design aims to increase the structural stability and electrochemical properties through the effective incorporation of rGO, mitigating volume expansion during redox reactions when redox reactions occur. In this composite structure, rGO serves as a conductive network that significantly enhances ion diffusion, while its excellent mechanical properties help mitigate the volume expansion of ZnCo₂O₄ during redox reactions. This dual action of rGO not only strengthens the structural stability of ZnCo₂O₄ microspheres but also enhances their electrochemical performance, providing an effective and practical solution. As expected, the ZCO@r-3 composite exhibited an initial discharge capacity of 1582.1 mAh g⁻¹ in the first cycle and initial reversible specific capacity of 1087.9 mAh g⁻¹ after the second cycle at 0.1 A g⁻¹. Even after 500 charge/discharge cycles under the same conditions, the composites maintained a reversible capacity of 966.7 mAh g⁻¹. This demonstrates exceptional cycling stability, validating the effectiveness of the rGO coating in enhancing the material's long-term performance. This confirms that the method proposed in this study effectively addresses the volume expansion issue of ZnCo₂O₄.</p>
