The integration of polyaniline (PANI) with single-walled carbon nanotubes (SWCNTs) offers a promising technique to improve the electrochemical performance lithium-ion battery (LIB) anodes. In this work, we report on synthesis and advanced optimization PANI/SWCNT composite anodes aimed toward further developing (Li+) storage capacity. A proper characterization, including SEM XRD, revealed well-defined morphology synergistic collaboration among PANI SWCNTs. Electrochemical evaluations showed that display predominant Li+ capacities, high specific capacity 528 mA g−1 at 100 g−1, 10 wt% SWCNT-doped (PANI/10 SWCNT) demonstrated an exceptional cycling 830 excellent retention (101% after 200 cycles). Cyclic voltammetry reduced charge transfer resistance improved ion diffusion kinetics. These improvements originate from correlative properties PANI’s redox activity SWCNT’s conductivity, which enable effective transport intercalation. This work features capability composites as superior-performance anode materials for LIBs, tending key difficulties energy density stability. discoveries establish importance additional investigation polymer–carbon nanocomposites in systems.
