Application of chemical synthesized polypyrrole for a rechargeable lithium battery

Electrochemically Active Polymers for Rechargeable Batteries

“…Polypyrrole has been produced by potentiostatic and potential-sweep techniques; − galvanostatic ,,− and chemical ,,− oxidation routes have also been utilized for the polymerization of pyrrole.…”

“…The maximum doping level of polypyrrole is independent of the doping anion, except for macroanions. But the doping level of polypyrrole and, consequently, the values of specific charge and energy attainable in Li/PPy cells at practical current densities strongly depend on the method used in fabricating the polymer electrode. ,, For example, Panero et al measured a specific energy of 151 W h kg -1 (based on the weights of the doped polymer and Li consumed) for a Li/LiClO 4 -PC/PPy cell with excess electrolyte containing a PPy film about 1 μm thin and doped to a level of y = 0.24. The polymer film was electrochemically grown in acetonitrile 119 under the conditions generally used about 10 years ago.…”

<b>Electrochemical properties and electrochemical impedance spectroscopy of polypyrrole-coated platinum electrodes</b>

“…Polypyrrole (PPy) and its derivatives, obtained either by chemical [1][2][3][4][5][6] or electrochemical [7][8][9][10][11][12][13][14][15][16] oxidation of the corresponding monomers, have been the subject, during the last years, to a large number of studies because of their many potential applications including gas sensors [17], transistors [18][19][20], photovoltaic cells [21], energy storage [22][23][24][25][26][27][28], protective coatings [29][30][31][32], etc.…”

Sensing characteristics of polypyrrole–poly(vinyl alcohol) methanol sensors prepared by in situ vapor state polymerization

“…However, PPy composite can be prepared by a rather easy and laborious fabrication process, i.e. vapor state polymerization [18][19][20]. The vapor state deposition was normally carried out by exposing an initiator containing activated substrate to pyrrole monomer.…”
