Предложен  способ  получения  электродного  материала  на  основе  полианилина (ПАни),  допированного  п-толуол-сульфокислотой (ПТСК) – ПАни-(ПТСК)0,5 –  смешением растворов  эмералдин  основания (ЭО) и ПТСК  в муравьиной кислоте в отношении 1 моль ПТСК на 2 мономерных звена в полимерной цепи полианилина. Электрохимические свойства пленки ПАни-ПТСК, политой на Ni подложку, исследованы методами циклической вольтамперометрии (ЦВА) и снятия зарядно-разрядных кривых в 1 М LiClO4 в пропиленкарбонате. Было показано, что введение допанта ПТСК приводит к  быстрому  достижению  стационарного  состояния ЦВА  и  значительно  увеличивает  емкость ПАни-ПТСК  электрода в апротонном  литиевом  электролите. При  увеличении  тока  заряда-разряда  от 1 А/г  до 10 А/г  емкость меняется  незначительно от 260 Ф/г до 244 Ф/г соответственно. Влияние п-толуолсульфокислоты в ПАни как допанта, введенного на стадии формирования полимерной матрицы, на морфологию, кристалличность и проводимость ПАни-(ПТСК)0,5 было исследовано методами ИК спектроскопии, рентгеноструктурного анализа, сканирующей электронной микроскопии.

The method for preparation of the electrode material based on polyaniline (PAni) doped by p-toluenesulfonic acid (PTSA) has been developed. PAni-(PTSA)0.5  was prepared by mixing solutions of emeraldine base (EB) and PTSA in formic acid at a 1 mol of PTSA to 2 monomer units ratio in the polyaniline chain. Electrochemical properties of the PAni-PTSA film casted onto a Ni support have been studied using cyclic voltammetry (CVA) and charge-discharge curves in 1М LiClO4 in propylene carbonate. It has been shown that the insertion of PTSA provides quickly attained steady state of CVA and enhances noticeably capacity of the PAni-PTSA electrode in aprotic Li electrolyte. If charge-discharge current is increased from 1 A/g to 10 A/g, capacity changes insignificantly from 260 F/g to 244 F/g, respectively. The effect of PTSA embedded in PAni as dopant at a stage of the formation of a polymer matrix on morphology, crystallinity, and conductivity of PAni-(PTSA)0.5 was studied by IR spectroscopy, X-ray analysis, and scanning electron microscopy.
