In today’s world Electricity is considered as an integral utility. We can never ever think of our lives without machines. Thus, electricity plays a vital role in functioning of the society. One of the portable and convenient sources of this electrical energy is a Battery. Battery is the basic yet most powerful part of any device. Thus, a bio battery is an energy storing device that is powered by organic compounds. Bio-Battery generates electricity from renewable fuels providing a sustained, on-demand portable power source. By using enzymes to break down organic compounds, bio-batteries directly receive energy from them. Bio-batteries are alternative energy
devices based on bio-electro catalysis of natural substrates by enzymes or microorganisms. This paper brings out an alternative solution to the conventional batteries which is not only a boon to the environment by being eco-friendly but also it is an end to worries about non-renewable and vanishing sources of energy (Siddiqui and Pathrikar, 2013)
