Abstract
The present invention provides a kind of electrode preparation method and super lithium capacitor fabrication method, and the preparation method of described electrode comprises the steps: a) active substance powder, conductive agent powder and binding agent powder proportionally to be stirred mixing；B) mixed powder is pressed into dry film；C) dry film is pressed in the metal forming of conductive pattern layer, forms described electrode.It is an advantage of the current invention that, higher energy density is had concurrently while keeping tradition super appearance high-specific-power feature, the non-proton ion of activity is activated by system electrochemical method and obtains energy-storage function, and this is very easy to realize in the industrial production, it is to avoid the complexity that existing document is mentioned, time-consuming, the technical process of power consumption.
Description
Technical field
The present invention relates to super lithium electric capacity field, particularly relate to a kind of electrode preparation method and super lithium electric capacity preparation side
Method.
Background technology
Super capacitor, i.e. ultracapacitor, also known as " electrochemical capacitor ", be a kind of in view of conventional physical electric capacity (i.e. electricity
Electrolysis condenser) and chemical cell between novel secondary electrochmical power source energy storage device, there is the power characteristic of electrochemical capacitor simultaneously
Energy energy storage advantage with battery.Additionally, relative to traditional capacitance and battery, super capacitor significant advantage also includes the long circulating longevity
Life (up to more than 100,000 times), broader use temperature range (-40～70 DEG C) and higher safety and reliability, be in
The fields such as front yard, industry, traffic and military affairs are of many uses.
Conventional Super electric capacity is owing to being limited by charge storage mechanisms and wet method technology for preparing electrode, and energy density is compared
Battery only has about 1/10th (i.e. 5-7Wh/kg), thus is restricted in many application scenarios.In order to overcome this bottle
Neck, various countries scientist attempts to battery high energy advantage, and a certain electrode (negative or positive electrode) in battery is incorporated into electric capacity
