Electrode performance includes four aspects

1. Chlorine evolution potential: Under certain conditions, the lowest potential of chloride ions is excited;

2. Polarizability: The potential difference between the current density of 200A/㎡ and 2000A/㎡ is also an indicator of coating activity;

3. Chlorine evolution efficiency: How much current is used to participate in the chlorine evolution reaction. Generally, the efficiency is greater than 88% at 25 degrees Celsius under the single measurement of our plate;

4. Enhanced life: 1mol sulfuric acid, 20000A/m2 current density, the electrode failure time.
