11. Solid electrolytes drop faster than non-solid electrolytes but remain at a slightly higher level.12. Solid electrolytes drop faster than non-solid electrolytes but remain at a slightly higher level. 13. Electrolytic capacitors with solid electrolyte cannot withstand transients or peak voltages higher than the surge voltage. 14. In ice and in certain solid electrolytes , the electric current is entirely composed of flowing ions. 15. The second challenge comes from developing the solid electrolyte , which is required to have these properties: 16. In 1834, Faraday discovered ionic conductivity in heated solid electrolytes Ag 2 S and PbF 2. 17. Besides his theoretical work, in 1897 Nernst patented the first lamp that used a solid electrolyte . 18. The non-solid electrolyte provide oxygen for self-healing purposes to reduce the leakage current. 19. In addition the solid electrolyte offers a very long time stability of the electrical and thermal characteristics. 20. Aluminum electrolytic capacitors with non-solid electrolyte are the best known and most widely used electrolytic capacitors.
