THE METHOD OF STANDARD POROSIMETRY .2. INVESTIGATION OF THE FORMATIONOF POROUS STRUCTURES

The results obtained by applying the method of standard porosimetry fo r investigation of different processes in batteries and other electroc hemical devices are discussed. The following processes were investigat ed: swelling and ion exchange of polymeric materials (membranes, condu cting polymers); pressing of powdered materials (PVC, Raney silver); t he influence of pore-forming agents; chemical and electrochemical sint ering of platinum catalysts; deposition of solid products in the pore volume of the cathode during reduction of SOCl2 in lithium batteries; structural changes during formation and cycling of lead and silver oxi de electrodes, etc.
