Polymer piece formula stromatolite solid aluminium electrolytic capacitor of multilayer core

The utility model provides a polymer piece formula stromatolite solid aluminium electrolytic capacitor of multilayer core, includes aluminium, aluminium oxide dielectric layer, conducting polymer solid electrolyte layer, carbon containing negative pole layer, contains silver -colored negative pole layer, lead terminal and plastic envelope part, its characterized in that: when lead terminal unilateral stromatolite core was more than two -layer or two -layer, outmost core be complete shape, and all the other are in core between the outmost and lead terminal and have the hole among them, and theedge of hole covers the insulating or low conducting material of one deck, the conducting material of middle filler metal material, hole middle zone with be the connection status with layer other negative pole of core are regional including silver -colored negative pole layer to formation electricity switches on. Through structural optimization, form the good route that switches on between each layer core and lead termina
