electrochemical
含义: Relating to or involving chemical reactions that produce or are caused by electricity; pertaining to the branch of chemistry concerned with the interrelation of electrical and chemical effects.
Electrochemistry underpins batteries, fuel cells, electrolysis, corrosion science, and electroplating. An electrochemical cell converts chemical energy into electrical energy (as in a battery) or uses electrical energy to drive a non-spontaneous chemical reaction (as in electrolysis). The electrochemical series ranks metals by their tendency to lose electrons, which is crucial for predicting corrosion behaviour. In modern research, electrochemical processes are central to hydrogen production, energy storage, and biosensor technology. Common collocations include 'electrochemical cell,' 'electrochemical reaction,' and 'electrochemical gradient.'

起源与历史
A compound of 'electro-' (from Greek ēlektron, amber — the substance used in early static electricity experiments) and 'chemical' (from medieval Latin chimicus, relating to alchemy). The field was established in the early 19th century by pioneers including Humphry Davy and Michael Faraday.
