ELECTRODE AND CURRENT COLLECTOR FOR ELECTROCHEMICAL CAPACITOR WITH DOUBLE ELECTRIC LAYER, AND ELECTROCHEMICAL CAPACITOR WITH DOUBLE ELECTRIC LAYER MADE THEREOF

摘要

FIELD: electrical engineering.;SUBSTANCE: invention relates to electrode to be used in electrochemical capacitor. Proposed electrode represents a polarisable electrode consisting of activated carbon material with, in fact, zero content of ash and low percentage of transition metals. In producing double electric layer capacitor (DEL-capacitor), polarisable electrode consisting of the mix of lead dioxide/lead sulphate is preferably used. DEL-capacitor can also incorporate acid-based electrolyte, for example aqueous sulphuric electrolyte. Electrode comprises current collector containing, preferably, basic metal consisting of lead or compound thereof and electrolyte-resistant protective coat material based on acid. Preferably, protective coat material is made from polymer base and conductive additive that can be applied on collector basic material by various methods.;EFFECT: improved power storage capacity.;32 cl, 5 dwg, 5 ex
