The study of interchange between chemical & electrical energy is Electrochemistry. The research is done on a solution flowing between an electron conductor & an ion conductor. The flow of electrons are governed by reduction & oxidation reactions. Television remote cell batteries, laptop batteries etc use electrochemistry to generate electricity. Since Electrochemistry has ways to power lives without using any fossil fuels & with minimum pollution to the environment, they are becoming popular by the day. Research projects on fuel cells, electroplating & electrochemical cells are being conducted in this field which made it possible the widespread utilization of solar energy.
