Abstract

The conductive polymer precursor, 3-hexylthiophene (3-HT), is successfully encapsulated in ca. 5 μm polyamide microcapsules by interfacial polymerization. The microcapsules are thermally stable up to 300°C, and electrochemically stable in a Li-ion battery electrolyte. Mechanical rupture of the microcapsules releases the liquid core and electropolymerization of the 3-HT monomer was analyzed using cyclic voltammetry. Scanning electron microscopy and vibrational (Raman) spectroscopy confirm the presence of newly formed poly(3-HT) thin films on model electrode surfaces. Encapsulation of battery additives such as 3-HT in microcapsules that remain latent and stable in the electrolyte until required may lead to enhanced battery performance and extended battery lifetimes.
