Improved structure of metallized safety film explosion-proof capacitor

Abstract

The invention discloses an improved structure of a metalized safety film explosion-proof capacitor. Graphene is mixed with activated carbon, and nickel oxide is doped to serve as a first electrode layer of a first polar plate; therefore, not only can the characteristic of good conductivity of the graphene be retained, but also the problem of low energy density of the graphene can be improved through nickel oxide, and the overall metalized safety film explosion-proof capacitor can be greatly improved in the aspects of conductivity and energy density. Furthermore, graphene is mixed with activated carbon and tungsten oxide is doped to serve as a second electrode layer of the second polar plate; therefore, through the mutual cooperation of the first electrode and the second electrode, the structure has better conductivity and larger surface area, and the internal resistance of the whole capacitor can be greatly reduced, so that the whole structure can have more complete capacitance characteristics, and has good performance in the aspects of specific capacitance value, power density, energy density and the like.
