Study of the influence of the electrodes production technological features on the electrochemical characteristics of supers-capacitor with the aqueous electrolyte

There are the tests results of the symmetrical carbon super-capacitors (on the sulfuric acid electrolyte), whose electrodes are prepared with two methods (spraying and calendering) from two coals: coal of brand XH-00W1 (China) and coal, developed by the authors together with the Latvian state institute of wood chemistry. It is shown that the specific characteristics of super-capacitor substantially depend on the specific mass of electrodes (mg/sm²), and also from the method of their production.
