What is Electrochemistry?

Electrochemistry is the branch of chemistry that studies the relationship between electrical energy and chemical reactions. It encompasses both the generation of electricity from spontaneous redox reactions (as in galvanic cells) and the use of electrical energy to drive non-spontaneous reactions (as in electrolytic cells). Electrochemical principles underpin batteries, fuel cells, corrosion, and electroplating.
