What is an Electrochemical Cell?

An electrochemical cell is a device that converts electrical energy into chemical energy. Electrolysis is a process in which an electric current passes through an electrolyte solution (or a molten electrolyte) to cause a redox reaction at the anode and cathode. The general electrochemical system is divided into two-electrode system and three-electrode system, and the three-electrode system is mostly used.

Applications of Electrochemical Cell

The electrochemical measurement method is to attribute the change of the chemical substance to the electrochemical reaction, that is, the potential, current or electric quantity in the system is used as a measure of the chemical reaction in the system. Cyclic voltammetry has long been known for its multi-functional applications in many fields such as chemistry, physical chemistry, biochemistry, and biology that involve the process of electron transfer.

The electrochemical cell of three-electrode system can potentially be used, not limited to, for the following characterization and measurements of electrically driven chemical reactions of metal materials, inorganic non-metal materials, organic polymer materials.

• Chemical analysis and synthesis
• Redox potentials
• Electron transfer mechanism and reversibility of a reaction
• Thermodynamic and kinetic studies
• Corrosion evaluation test
• Battery and energy studies
