adj.relating to the interaction between electricity and chemical reactions. Often describes the conversion of chemical energy into electrical energy or the reverse.


SIMPLE

The battery uses an electrochemical process to store energy.

CONTEXTUAL

Scientists are developing new electrochemical sensors that can detect tiny amounts of toxins in water.

COMPLEX

The efficiency of the fuel cell depends on the electrochemical reaction occurring at the interface between the catalyst and the electrolyte.

Instead of using only pressure or heat to separate salt from water, electrochemical desalination uses electrical reactions and specially selected electrodes to draw charged salt particles out of the solution.
