The study aimed to develop a sea battery that would make an alternative means for recent batteries that are available in the market. It is environmentally friendly and economical yet with competitive performance in terms of supplying power to some suitable electrical devices.
Dissolved-oxygen seawater batteries rely on the corrosion of a reactive metal anode and the reduction of oxygen at an inert cathode to generate a potential voltage when immersed in seawater. In connection, this study also aimed to evaluate the feasibility of constructing a seawater battery using cheap readily-available materials such as copper and zinc metal plates.
Results showed that the copper cathodes and zinc anodes outperform other metals but are inexpensive. The project developed partly solved these problems by using the seawater battery wherein the functionality of metallic plates as well as the seawater as electrolyte clearly differ from any other batteries that are toxic to surroundings, thus, sufficient to supply 12-volt lighting loads and 12-volt battery operated appliances which can be used for commercial and residential purposes. Also, a monitoring module is added to the battery to monitor the different readings on the output voltages and currents of the said device.
