This article outlines a simple method for identifying the thermodynamic limits to electrochemical reversible energy storage systems based on the Nernst equation and previous results obtained from work on reversible chemical hydrogen sorption. The model is successfully validated for seven reversible battery cell examples. The findings of this work substantiate the idea of a general thermodynamic principle limiting reversible chemical energy storage and suggest a change of paradigm towards a global understanding of the matter.

“…Polyanilines have been studied extensively due to the fundamental interest in reaction mechanisms and for their applications to practical devices for energy storage, electrochemical sensors, electrochromic devices, EMI shielding, corrosion protection and others (Kobayashi et al 1984;DeBerry 1985;Kitani et al 1986;Genies et al 1988;Zhou et al 1990;Baxskai et al 1993;Chen et al 1996;Hugot-Le-Goff 1997;MacDiarmid 1997;Park 1997;Trivedi 1997;Malinauskas 1999;Wang and Jing 2005). Application of CPs in energy storage devices is well known (Conway 1999) and recent studies (Hughes et al 2002;Gupta and Miura 2005;Martha et al 2005;Peng et al 2006) in this area gave impetus to fundamental and applied research on CP-based new materials.…”

Studies on biphenyl disulphonic acid doped polyanilines: Synthesis, characterization and electrochemistry

2012

In this article, we report on the results obtained for the efforts we made to bring processability to the conducting polyaniline and substituted polyanilines by designing and synthesizing a new disulphonic acid with a biphenyl moiety as spacer group, viz. 4,4-biphenyldisulphonic acid (BPSA). When doped, the disulphonic acid acts as a spacer group between the polyaniline chains and facilitates increase in solubility and conductivity. The spacing effect is maximized when BPSA is used as doping agent in in situ polymerization reactions. The conductivity of polyaniline doped by BPSA is 4 S/cm and for the substituted polyanilines it ranged from 2 × 10 −5 to 8 × 10 −4 S/cm.

“…In this work, polyaniline deposits were formed by different methods in an aqueous 1.5 M H 2 SO 4 solution containing the aniline monomer [1,2]. The morphology of coatings and their chemical composition were characterized by scanning electron microscopy and X ray photoelectron spectroscopy, respectively.…”
