Description

technical field [0001] The invention relates to a laminated structural component for storing and discharging charges or electric energy. Background technique [0002] Ordinary capacitors and rechargeable batteries are common components used to store and discharge charge or electrical energy. [0003] Traditional semiconductors containing PN junctions can conduct charge and current inside when a forward voltage is applied, but do not conduct when a reverse voltage is applied, and a very low reverse voltage (such as >5V) may break it down. [0004] A supercapacitor, also known as an electric double layer capacitor or an electrochemical capacitor, is an electrochemical component that stores energy by polarizing an electrolyte. Supercapacitors can be regarded as two non-reactive porous electrode plates suspended in the electrolyte, which actually form two capacitive storage layers. The specific surface area of ​​the porous electrode plates is huge, so the capacitance is larg...

Problems solved by technology

In fact, this device has basically no practical value, because the existence of the insulator makes it basically unable to charge, and can only accumulate positive and negative charges on both sides of the insulator, and the closely connected p and n-type semiconductor plates do not play any role, and basically cannot discharge

[0007] The invention with application number 2006100883842 relates to a dielectric formula for high-voltage capacitors. In order to solve the shortcomings of current dielectrics in the field of high-voltage applications, such as low withstand voltage, low dielectric constant, and large dielectric loss, the present invention uses barium titanate BaTiO380% , calcium titanate CaTiO38-10%, zinc oxide ZnO 0.1-2%, manganese dioxide MnO20.1-1%, didysprosium trioxide Dy2O34-8%, magnesium titanate MgTiO33-5% to form the dielectric, so that the The AC withstand voltage value of the capacitor is increased to 1.5kV / mm, the dielectric constant ε≈6000, and the dielectric loss is ≤0.0006 in the AC working current of 100Hz-10kHz, which is suitable for bypassing, coupling or for low frequency loss and In frequency discrimination circuits where high capacitance and stability are not important
