Background:

• Lithium-ion batteries (LIBs) require advanced negative electrode materials for improved performance.
• Synergistic fusion of electroactive components can enhance electrochemical properties.

Purpose of the Study:

• To synthesize and characterize reduced graphene-oxide (rGO)-coated Zn2SnO4@NiO nanofibers (ZSO@NiO@G NFs).
• To evaluate the electrochemical performance of ZSO@NiO@G NFs as negative electrodes for LIBs.

Main Methods:

• Electrospinning and calcination processes were used for material synthesis.
• The material's structure and electrochemical properties were analyzed.

Main Results:

• The ZSO@NiO@G NFs exhibited a porous one-dimensional structure with effective strain relaxation.
• The composite demonstrated a high reversible capacity of 1060 mAh g-1 at 1000 mA g-1.
• Exceptional cycle lifespan exceeding 1600 cycles was achieved.

Conclusions:

• The synergistic fusion of ZnO, SnO2, and NiO, combined with rGO coating, results in superior electrochemical performance.
