chemical reaction

Electrical energy in electronic equipment was obtained from the results of the chemical reactions that take place in the form of spontaneous redox reactions. In a redox reaction occurs eletron transfer or removal of an element to another. Electron flow shows the flow of electricity.

In a battery or batteries are used Seang, a chemical reaction takes place that produces an electric current. The opposite process is the use of electrical energy to produce a chemical reaction. For example in the metal plating and shock the batteries or battery.

Electrochemical cell divided by 2 over reaction, ie voltaic cells and electrolysis cells. The fundamental difference is only between the two as follows:

Tues Volta

The chemical reactions that take place are spontaneous and produces an electric current. Cathode is the positive pole and the anode is the negative pole, an example of using batteries and the batteries.

electrolysis cell

An electric current causes the course of a chemical reaction. Cathode is the negative pole, while anatode is the positive pole. Example: gilding, metal pemurnia in mining, and peyetruman battery.

Okk so simple little discussion about the electrochemical cell, I hope this simple article can provide information that would benefit us all.
