Abstract:
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.
