Description
Technical Field
The invention relates to the field of materials, in particular to an activated carbon material for a super capacitor, and also relates to a preparation method and application of the carbon material.
Background
Nowadays, the use of fossil fuels leads to an increasingly depleted energy source and an increasingly serious environmental pollution. Therefore, the energy crisis and environmental protection are two major problems facing all countries in the world, and the development of clean, sustainable, safe and efficient energy conversion and storage equipment is becoming one of the hot spots of current research. Among them, the successful development of supercapacitors is a historical breakthrough in energy conversion and storage devices.
A supercapacitor (also referred to as an electrochemical capacitor, an electric double layer capacitor), as a new type of energy storage device, has a higher energy density than a conventional capacitor; compared with a secondary battery, the lithium ion battery has higher power density, charge and discharge efficiency and longer cycle life. The performance of supercapacitors is affected by a number of factors, one of which is important is the material from which the electrodes are made. Among various electrode materials, carbon materials are widely concerned by researchers because the carbon materials have huge specific surface area, excellent electric and thermal conductivity and good chemical stability, and the pore size distribution of the carbon materials can be regulated and controlled in the preparation process. At present, raw materials for preparing porous carbon can be classified into 2 major categories according to the source of the raw materials: fossil fuels and biomass. Compared with the characteristics that fossil fuel raw materials are non-renewable, expensive, serious in environmental pollution and the like, the biomass material has the advantages of being rich in sources, low in cost, free of pollution and the like, can solve the problem of long-term development of the super capacitor, and has great significance for environmental protection.
The semen Citri Grandis is seed of Rutaceae plant fructus Citri Grandis (Citrus maxima, Merr.), and contains limonin and its analogs (mainly limonin and nomilin), flavonoid compounds (mainly naringin, etc.), fatty acids, proteins and other mineral elements. However, the research that the shaddock kernel biomass is used as a precursor to prepare the carbon material electrode and is applied to the super capacitor is only reported.
