Summary: The concept of the organic rechargeable battery is introduced. This battery is using urea as oxidation half and the aqueous extract of chickpea as reduction half due to the reversible electrochemical oxidation and reductions of the of the urea and chickpea proteins. Organic rechargeable battery is composed of five cells. Each of the half cell of which is made of a cubical container of high density polyethylene joined to the other through epoxy resin. Non porous graphite rods of 40 mm diameter and 400 mm length were used as the inert electrodes of the battery. The electrodes were placed in aqueous solutions of urea and chick pea extract in separate containers. Sodium hydroxide was used as the electrolyte of the process. The experimental conditions for this five cell battery were optimized. The net voltage and the stability of the voltage were investigated.

The variation in stability and voltage was investigated as a function of the salt bridge, concentration of electrolyte, amount of oxidizing and reducing agent and the viscosity of the media. The battery prepared was giving a voltage of 9.5 volt.Keywords: Organic rechargeable battery, Urea oxidation, Chickpea reduction, Low power battery, Protein reduction

Introduction

Oxidation and reduction reactions are important due to their biological significance, energy generation and energy storage [1-3]. The oxidation process is also important for the generation of electricity in fuel cells [4,5]. The role of oxidation and reduction in cosmetics and cosmaceuticals is also important and hair removing and hair curling are also the result of these reactions [6,7]. Both, these phenomena are due to the oxidation and reduction of sulfur-containing proteins and amino acids. The amino acids cysteine and cystine are the oxidized and reduced form of each other. In addition to hair, sulfur-containing amino acids are also found in pulses. The metabolic activities are associated with the generation of urea from the amino acids which is produced by the oxidation of amino acid [8]. Urea may pass through oxidation under appropriate conditions [9] and the anodic oxidation of urea is also reported [10].

We believed that in aqueous solution the oxidized form of urea remains in equilibrium with the urea. It may form a cell if coupled with a half cell observing reduction reaction. In case of the tendency of the half cell for electrolytic reverse reaction, the resulting cell will be a rechargeable cell. Recently our research group introduced a rechargeable battery and voltaic cell using protein for the storage of electricity [11]. Voltaic cells are important in terms of the transformation of chemical energy into the electrical energy. Electricity generation in living systems is important in the defense of the organisms or other important functions. All these involve the biochemically active compounds including proteins.

The present work is aimed to investigate the possibility of organic pollutants or other organic waste to be utilized for the storage and generation of electricity. This will lead to reduction...
