Abstract
The invention provides a manufacture method of a button capacitor. The manufacture method of the button capacitor comprises the following steps of (1) mixing activated carbon, acetylene black, a bonding agent and Teflon in proportion, adding solvent, performing stirring and then heating stirred paste; (2) coating the heated paste on the surface of an aluminum sheet, using a roll drum to roll, dry and punch the aluminum sheet to form a pole piece; and (3) placing the pole piece and a film into a button casing, filling electrolyte and sealing an opening to form the button capacitor. Compared with the prior art, the button capacitor manufactured by means of the method has good capacitance characteristics and large-current charging and discharging performance.
Description
Technical field
The button capacitor that the present invention relates to a kind of acquisition has good capacitance characteristic, and high rate during charging-discharging is the preparation method of button capacitor preferably also.
Background technology
Capacitor has been widely used on the electronic product as a kind of electronic component, it carries out storage and the discharge of electric energy, it might discharge and recharge under big current conditions, yet present more capacitor, for example the capacitance characteristic of button capacitor can not be satisfactory, and especially the charge-discharge performance in big current conditions has much room for improvement.
Summary of the invention
The technical problem that the present invention mainly solves is the high rate during charging-discharging deficiency of present button capacitor.
In order to solve the problems of the technologies described above, the embodiment of the invention discloses a kind of preparation method of button capacitor, may further comprise the steps:
(1), active carbon, acetylene black, binding agent and polytetrafluoroethylene are proportionally mixed, add stirring solvent, the pastel after will stirring again heats;
(2), the pastel after will heating is coated to the aluminium flake surface, rolls with the roller drum, drying is stamped into pole piece;
(3), pole piece and barrier film are put into the button shell, pour into electrolyte, seal and form the button capacitor.
In a preferred embodiment of the present invention, the mass ratio of active carbon, acetylene black and the polytetrafluoroethylene of step (1) is 5:3:2.
In a preferred embodiment of the present invention, the solvent of step (1) is polytetrafluoroethylene, ethanol or deionized water.
In a preferred embodiment of the present invention, the heating-up temperature of step (1) is 300-400 degree centigrade, and be 2-3 hour heating time.
