Electrochemistry
Electrochemistry is the branch of chemistry that studies the interconversion of chemical energy and electrical energy through electron-transfer reactions at electrode surfaces.
Overview
It governs technologies ranging from batteries and fuel cells to electroplating and industrial electrolysis — the last of which made aluminum production economically viable. In living systems, electrochemical gradients drive every nerve impulse and muscle contraction, making the field fundamental to both engineering and biology.
Why it matters
Electrochemistry has shaped every major industrial society, enabling portable electronics, electric vehicles, and continuous glucose monitoring sensors. Its principles are now essential to renewable energy storage and to treating industrial wastewater and recovering metals from electronic waste.
