Abstract

The invention discloses a flat capacitor electrode foil based on thermal spraying. The structure comprises thermal spraying layers, an electrode substrate and a leading-out flat cable, the thermal spraying layers are scattered and attached to the upper and lower surfaces of the electrode substrate. One end of the lead-out flat cable is integrally connected with the edge of the electrode substrate,so that the surface of the electrode foil is full of aluminum powder particles, the surface area of the electrode foil is increased by 10-2000 times. According to the invention, a thermal spraying method is adopted to replace traditional aluminum powder micro-particles to be used as a material for increasing the surface area; after the electrode plate is cut, molten aluminum powder is mixed withinert gas to be sprayed out and attached to the surface of the electrode plate at high temperature and high pressure, the electrode plate is not prone to falling off after being cooled, the thicknessof an attachment layer can be well controlled, a firm covering layer is formed, and therefore the abrasion resistance, the corrosion resistance, the oxidation resistance and the heat resistance of thesurface of the electrode plate are improved.

Description

technical field [0001] The invention relates to a flat-stack capacitor electrode foil based on thermal spraying, which belongs to the field of capacitors. Background technique [0002] Capacitance, also known as "capacitance", refers to the charge storage capacity under a given potential difference, denoted as C, and the international unit is farad. Generally speaking, charges will move under force in an electric field. When there is a medium between conductors, it will hinder the movement of charges and cause charges to accumulate on the conductors, resulting in the accumulation and storage of charges. The amount of stored charges is called capacitance. Because capacitors are one of the electronic components widely used in electronic equipment, they are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. Capacitors are divided into electrolytic capacitors, solid capacitors, etc. [0003] The prior art published ...
