Abstract

with ∼90% capacity retention after 100 cycles. Thermogravimetric analysis confirms the compositional robustness and enhanced thermal stability of the composite structure, while electrochemical impedance spectroscopy demonstrates reduced charge-transfer resistance and improved interfacial kinetics compared with pristine silicon. These results highlight the critical role of compositional optimization in rGO-Si composite anodes and provide a practical strategy for developing durable and high-performance silicon-based anodes for next-generation lithium-ion batteries.
