In the electrolysis process, the electrolyte solution undergoes electrochemical reaction under the action of electric field, and reduction and oxidation reactions occur at the cathode and anode respectively. One important application of electrolysis technology is water electrolysis, which produces hydrogen and oxygen by electrolyzing water.
