Capacitors with a double electric layer can own the best density of capacity, essentially exceeding corresponding values of usual condenser systems, therefore them still name supercondensers. The active material for polarized electrode should be chemically and electrochemically proof to each making part of electrochemical system, providing a condition of blocking of course faraday's processes through interphase border. Besides with the purpose of achievement of high value of a ratio capacity / volume it is necessary aspires to the maximal development of an active surface, keeping thus the certain, high enough level of electroconductivity. Global experience shows, that for today the greatest attention is involved in two kinds of materials - the activated carbon structures and highporous electrospent ceramics. As a rule, advantage first of them in a kind of its cheapness, resistance and stability possesses. However the technology of its reception is in most cases connected to ecologically harmful influence. Therefore reception of the non-polluting, cheap activated material is a task of prime value for today. Product Description popup.authors popup.nrat_date 2020-04-02 Close
