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

The results obtained by applying the method of standard porosimetry for investigation of different processes in batteries and other electrochemical devices are discussed. The following processes were investigated: swelling and ion exchange of polymeric materials (membranes, conducting polymers); pressing of powdered materials (PVC, Raney silver); the influence of pore-forming agents; chemical and electrochemical sintering 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 oxide electrodes, etc.
