<p>Compact leak-proof electrolytic capacitors including, between the anode and the cathode, a layer of a solid polymer electrolyte, are disclsoed. The solid polymer electrolyte comprises (a) a solid solution of at least one salt selected from the group consisting of (i) alkali metal salts, (ii) alkaline earth metal salts, (iii) transition metal salts, (iv) ammonium salts, (v) organic ammonium salts and (vi) thallium salts of at least one acid selected from the group consisting of monobasic, dibasic and tribasic acids other than haloid acids in a polymer, and (b) a crosslinking agent selected from the group consisting of di-, tri- or polyisocyanates, di- and multifunctional acids, di- and multifunctional amines and di- and multifunctional unsaturated compounds which crosslink the polymer. Methods of making such capacitors are also disclosed. Rolled solid electrolyte capacitors of this type are characterized by low volume, absence of electrolyte leakage, and minimum dielecric deformation, and are capable of delivering intense bursts of current on demand, thereby being suitable for use in biomedical electronic devices such as cardiac pacemakers and defibrillators implanted in the human body.</p> |
