Abstract
The development of advanced single lithium-ion conducting polyelectrolytes is critical
for enhancing the performance and safety of lithium-ion batteries. This study focuses
on synthesizing and characterizing lithium bis(trifluoromethanesulfonyl)imide
(LiTFSI) functionalized with poly(butyl acrylate-co-styrene) (P(BA-co-St))
nanoparticles to create a single lithium-ion conducting polyelectrolyte. The
functionalized nanoparticles were synthesized via seeded emulsion polymerization,
and their structure and morphology were confirmed using techniques such as Fourier
Transform Infrared Spectroscopy (FTIR), X-Ray diffraction analysis (XRD), Total
Solid Content (TSC), and Particle Size Analysis. Electrochemical properties, including
ionic conductivity, were evaluated using a Prostat (PRS-801) resistance system with a
miniature two-point resistance system setup. The synthesized LiTFSI-P(BA-co-St)
nanoparticles exhibited enhanced ionic conductivity and increased lithium
concentration compared to traditional electrolytes. The thermal stability and
mechanical properties of the samples were also assessed, showing improvements
suitable for practical applications in lithium-ion batteries. Overall, the incorporation
of P(BA-co-St) nanoparticles into LiTFSI significantly enhances the performance of
the polyelectrolyte. This study provides valuable insights into designing highperformance
single lithium-ion conducting polyelectrolytes, contributing to safer and
more efficient lithium-ion batteries.
