An Electrochemical Synthesis is a chemical reaction that is caused by the movement of electrical current. These processes are a type of oxidation-reduction chemical reactions in which one atom or molecule loses an electron to another atom or molecule. In electrochemical process, the atoms or molecules in the reaction are relatively far apart from each other compared to other reactions, forcing the electrons being transferred to travel a greater distance and thereby produce an electrical current. Many natural phenomena are depend on Electrochemical Methods, such as the corrosion of metals, the ability of some sea creatures to produce electrical fields, and the workings of the nervous systems of humans and other animals. They also play an important part in modern Chemical technology, most prominently in the storage of electrical power in batteries, and the electrochemical process called electrolysis is important in modern industry. Neurons use electrochemical processes to transmit data through the nervous system, allowing the nervous system to communicate with itself and with the rest of the body. The electrochemical instruments market is segmented on the basis of products, methodologies, end user, and region. The global electrochemical instruments market was valued at $1,713.0 Million in 2014 and is poised to increase at a CAGR of 5.2% during the forecasted period.
