Performance Study of Zn / ZnCl2,  NH 4Cl / Polyaniline / Carbon Battery

Abstract

A secondary battery of the type normalZn/ZnCl2 , NH4normalCl/normalpolyaniline/normalporous carbon is described. The polymer was electrodeposited on porous carbon rods, in the form of consistent, rather thick, highly porous, and low‐resistance layers. The battery was assembled in a configuration similar to that of the classical MnO2‐normaltype R‐6 dry cell. The performance of the battery has been studied, and it shows characteristics comparable to those of conventional systems: moderate specific energy (50–100 Wh · kg−1), very good coulombic efficiency (70–100%), low self‐discharge rate (<1% day), and excellent cyclability at high current densities.

Synthesis and characterization of poly(o‐ethoxyaniline): A processable conducting polymer

“…Cyclic voltammogram of PEA in (1) sulfuric markedly with the oxidation potential of the oxidant. The higher molar ratio of oxidizing agent (M,,) yields a low polymerization efficiency whereas M,,/ Me, = 0.5 provides a better polymer yield.…”

Immobilization of Lactate Dehydrogenase on Electrochemically Prepared Polyaniline Films

“…This is because the electropolymerization allows control over both the thickness and spatial location of the electrode modi®cation. In this context the remarkable chemical stability, solubility in a variety of solvents and processability of polyaniline (PANI) into ®lms and ®bres has led to its increased interest for various applications such as in batteries [1], electrochromic devices [2] and biosensors [3±4]. The advantage of using polyaniline in the technical development of biosensors lies in its usefulness as an enzyme entrapment matrix coupled with its physico-chemical transducer characteristic to convert the biochemical signal into an electrical signal.…”

All-solid secondary polyaniline-zinc battery

“…Some of the reported values of energy density using aqueous electrolytes are in the range 20.7-146.4 Ah kg -1 [10][11][12][13][14][15]. 189-195 193 It can be seen in Fig.…”

“…Work on PANI-Zn batteries has mostly been based on liquid electrolytes [10][11][12][13][14][15][16][17][18]. However, no report is available in the literature on the use of solid electrolytes in PANI-Zn batteries.…”
