Electrochemical characteristics of bilayer film of polyaniline composite positive with polymer electrolyte binder/polymer electrolyte for Li-ion batteries

Mesoporous Tungsten Trioxide Polyaniline Nanocomposite as an Anode Material for High‐Performance Lithium‐Ion Batteries

“…In the case of PANI/m‐WO 3 , the coulombic efficiency of the composite is 67.2 % and the reversible capacity in the first cycle is 1064 mAh g −1 which is much higher than the theoretical capacity (693 mAh g −1 ). However, the reversible capacity of pure PANI in the first cycle is 30 mAh g −1 (Figure ), which is comparable with the values reported in literature, and it seems that PANI has little contribution to the capacity of the m‐WO 3 . Previous research also showed that a higher capacitance was observed in PANI/m‐WO 3 electrode used in electrochemical capacitors application compared with m‐WO 3 .…”

Swelling and volume changes of polyaniline upon redox switching

“…The protons generated by this reaction are compensated, to some extent, by the previous expulsion. (iii) The volume increase part, with anion ingress, should correspond to reaction (4). In this reaction the quinoid structure is developed, as well as the backbone charge modification.…”

“…The great interest in conducting polymers in the last decades, in particular aryl amine derived polymers -such as poly(aniline) (PANI) and its derivatives -is caused, among other factors, by the many applications proposed, such as actuators [1,2], electrochromic devices [3], secondary batteries [4,5], supercapacitors [6], sensors [7][8][9] and many others [10][11][12]. Poly(aniline) and its derivatives undergo volume changes upon redox cycling, specially in the first redox step, namely when going from the fully reduced form, leucoemeraldine (LE) to the intermediately oxidized one, emeraldine (EM).…”

Pyrolysis–gas chromatography/mass spectrometry applied to the identification of different states of polyaniline

“…Conducting polymers, in particular aryl amine polymers such as polyaniline (PANI) are proposed to be used for many applications [1][2][3][4][5][6][7][8][9][10][11][12]. Due to their potential applications and interesting characteristics, the electrochemistry of aryl amine polymers have been intensively studied [13][14][15][16][17].…”
