Description: Manufacture of Carbon Materials with a Specific Area and High Porosity (Holes) in a New Way
Energy has long been known as the moving engine of human societies, and with human progress, its importance and impact on human life have increased. With the discovery of fire, plant biomass resources have been used as a source of energy needed by mankind. With the discovery of coal and its combustion properties, its exploitation as a source of thermal energy was developed. With the discovery of oil and the recognition of its advantages over coal, especially in the field of transportation, the use of coal gradually decreased and crude oil was recognized as the most crucial source of human energy. Crude oil is supplied from limited sources and it is not possible to continue the growth of its consumption at a very fast pace for a long time. Therefore, the use of gases with crude oil, which is easily converted into liquid, became popular. All resources used by humans to provide energy, from biological hydrocarbons to natural gas, produce various environmental pollutants when consumed in the form of combustion. With global warming and limited fossil fuel resources, the world is continuously driven toward using alternative and clean energies. For this reason, with the rapid growth of the market in the field of portable electronic devices and hybrid electric vehicles, the ever-increasing and essential need for biocompatible energy sources with high power is well felt. Electrochemical energy production is significant as an alternative to energy or power sources due to their stability and biocompatibility. Electrochemical energy storage and conversion systems include batteries, fuel cells, and supercapacitors. All of these energy storage devices have an anode electrode, a cathode electrode, and an electrolyte, in which activated carbon and other metal materials are used in combination with carbon to perform chemical reactions. Carbon has been recognized as a basic electroactive material for more than 40 years due to its unique chemical and physical properties. The advantages of carbon materials include high conductivity, controlled porous structure, processability and compatibility in composite materials, and relatively low cost makes carbon materials attractive for many applications. The first two features of high conductivity and high surface area are important factors for electrochemical supercapacitors and the cathode electrode of fuel cells and the anode electrode of batteries. If these two factors (i.e. conductivity and surface) are low, the maximum power density of the capacitor will be limited. Using nanotechnology, it is possible to prepare light, thin, and cheap electrodes that have better efficiency than conventional electrodes, and in this field, active carbons, carbon aerogels, carbon fibers, and carbon nanotubes form different carbon materials that It is mainly used as an electrode material for energy storage systems. As mentioned above, high surface area is one of the benefits of carbon materials. In this project, carbon materials with a high specific surface area and high porosity (holes) will be produced in a new way, and the simplicity of construction, the cheapness, and non-toxicity of the raw materials, the possibility of loading a large amount of carbon material and the possibility of producing a large amount of porous carbon will reduce The price of energy storage devices and increase in efficiency will lead to the commercialization of these devices.
