Over the last decades we are witnesses of astonishing development of different electrode
materials for alkali-ion and metal-air batteries, supercapacitors, and supercapattery. Even
so, some rather old electrochemical systems have still space for further improvement.
Seawater-activated primary battery, as another example of the old systems, discovered in
1878 and developed by Bell Telephone Laboratories in 1945 as the power source for electric
torpedoes, are used for a wide range of applications. Among many different cathode
materials, silver chloride (AgCl) and lead chloride (PbCl2) are most widely applied. An
improvement of AgCl synthesis is reported in our previous work in which the fast and lowcost modified process of successive ion layer adsorption and reaction (SILAR) is effectively
applied to form carbon felt-silver chloride cathode materials for primary cell.
In this work we investigated electrochemical synthesis of polypyrrole on a carbon felt
(CF/PPy) electrode. Furt...her, the CF/PPy electrode is modified by AgCl by applying modified
SILAR method. Using the cyclic voltammetry and charge-discharge techniques, it is shown
superior behavior of composite CF/PPy-AgCl electrode. For the possible rechargeable
aqueous based magnesium alloy AZ63 |3.5% NaCl | CF/PPy-AgCl cell in the current range of
135 to 1350 A g-1 the specific capacity in the range of 35-25 Ah kg-1, energy of 45-25 Wh kg1 and power of 100 to 1600 W kg-1 are obtained. Also the cyclic stability is determined, and
concluded that such a simple cell using small photovoltaic cell could be charged at least 100
times, depending of Mg-alloy mass. The possibilities of further improvement of the system
is considered.
