Abstract
An investigation is conducted on enhancing lithiumion intercalation and conduction performance of transparent organo tantalum oxide TaO y C z films by addition of lithium via a fast cosynthesis onto 40 Ω/□ flexible polyethylene terephthalate/indium tin oxide substrates at the short exposed durations of 33–34 s using an atmospheric pressure plasma jet APPJ at various mixed concentrations of tantalum ethoxide TaOC2H55 and lithium tertbutoxide CH33COLi precursors Transparent organolithiated tantalum oxide Li x TaO y C z films expose noteworthy Li+ ion intercalation and conduction performance for 200 cycles of reversible Li+ ion intercalation and deintercalation in a 1 M LiClO4propylene carbonate electrolyte by switching measurements with a potential sweep from −125 to 125 V at a scan rate of 50 mV/s and a potential step at −125 and 125 V even after being bent 360° around a 25cm diameter rod for 1000 cycles The Li+ ionic diffusion coefficient and conductivity of 62 × 10−10 cm2/s and 60 × 10−11 S/cm for TaO y C z films are greatly progressed of up to 96 × 10−10 cm2/s and 78 × 10−9 S/cm for Li x TaO y C z films by cosynthesis with an APPJ
