SOLID ELECTROLYTE AND ELECTRODE-ACTIVATED MEMBRANE WITH ITS EMPLOYMENT Russian patent published in 2003 - IPC

FIELD: solid polymer ion conductors, namely, ion-conducting polymer electrolytes which can be used in electrochemical devices, specifically, in electrode-activated membranes. SUBSTANCE: given solid electrolyte contains copolymer based on acrylonitrile and butadiene carrying over 17.0 per cent by mass bonds of acrylonitrile or copolymer based on acrylonitrile and butadiene containing over 17.0 per cent by mass bonds of acrylonitrile and additionally under 5.0 per cent by mass of monomer residue of unsaturated carbonic acid. Solid electrolyte contains cobalt chloride (II) in the capacity of inorganic salt of metal with following proportion of components, molecular per cent,: copolymer of acrylonitrile and butadiene 99.00- 99.80; cobalt chloride (II) 0.20-1.00. Electrode-activated membrane includes layer of solid polymer electrolyte and metal current tap in which layer of solid polymer electrolyte has composition in mole per cent: copolymer of acrylonitrile and butadiene containing over 17.0 per cent by mass bonds of acrylonitrile or copolymer based on acrylonitrile and butadiene containing over 17 per cent by mass bonds of acrylonitrile and additionally containing under 5.0 per cent by mass monomeric residue of unsaturated carbonic acid - 99.00-99.80 and cobalt chloride (II) -0.20-1.00 and is 10- 150 mcm thick. Solid polymer electrolyte of proposed composition has conductance of the order of 10^-8Ohm^-1cm^-1 and cobalt (II) detection limit 10^-6mole/l. Proposed solid polymer electrolyte can be utilized in electrode-activated membrane showing good operational characteristics and simple design.
