Electrolysis is widely used in industry, because it is possible to isolate some key substances for many production processes, such as aluminum, chlorine, sodium hydroxide, etc. In addition, it is also a process that purifies and protects coating of various metals. Electrolysis occurs only with power supply through a generator, such as a battery, for example. To understand for the graphite powder for li-ion battery anode this is the best deal here now.
To understand how it happens, look at the following scheme:
The generator pulls the electrons from the positive pole anode of the electrolyte bowl and transfers them to the negative pole (cathode). This is shown by the semi-reactions:
1st Half Reaction: The generator attracts the A- anions to the positive pole and forces them to lose electrons: THE- A0 + electron
2nd Semi-Reaction: The generator makes the C + cations receive the electrons: C ++
