FIELD: electricity.
SUBSTANCE: current collector is used in capacitor with aqueous or non-aqueous electrolyte, such as aqueous sulphuric electrolyte. Conducting base of current collector can be made from a variety of conducting metals, but preferably consists of plumbum or plumbum alloy. That part of conducting base which will be in contact with electrolyte is equipped with protective layer which has been formed by applying to that part of one or more layers of one or more materials of protective coating. Each protective coating material consists at least of conducting carbon powder and polymer bonding agent which is resistant to electrolyte. Preferably, but not obligatory, material(s) of protective coating is(are) applied to conducting base in the form of paste which is then subject to stage of solvent evaporation and to stage of thermal treatment. The resulting protective layer is actually free from pores through which electrolyte can penetrate.
EFFECT: increasing impact-and-vibration resistance, possibility of obtaining stable actuation voltage by enabling the control of armature travel and adjoining of armatures to cores when controlling the item parametres, increasing energy and power parametres, stability of operation and reliability.
