What is electrochemistry?

Electrochemistry is the scientific study of chemical processes that move electrons, and particularly how and when that movement creates electricity. Most electrochemistry focuses on understanding and improving chemically-caused electrical reactions. For example, electrochemists may study the impact of energy storage in different chemicals or look for ways to generate more electricity from the same substance. Electrochemistry also evaluates corrosion caused by the movement of electricity. Electrochemistry is a branch of physical chemistry, which deals with the larger question of how the laws of physics apply to atoms and chemical reactions. It should not be confused with the similarly-named chemical physics, which focuses more on physics than on chemistry.
