Often reduce rapidly.To improve this problem, a kind of electrode material for being suitable for il electrolyte characteristic is developed, is phase
Close the key point of research.
Three-dimensional porous carbon refers to the carbon material with three-dimensional communication structure and abundant pore size distribution.This material often also has both
The features such as bigger serface, lightweight, high conductivity.These features have three-dimensional porous carbon in fields such as electrochemical capacitance, batteries
Huge application potential.It is especially noted that the advantage of three-dimensional porous carbon is its connection compared to conventional porous carbon
Network-like structure, this three-dimensional structure is particularly suitable for the infiltration of electrolyte and the mass transport process of ion.Therefore, three-dimensional more
Many characteristics of hole carbon become the ideal electrode material with il electrolyte cooperation.However, preparation at present is three-dimensional more
The technology of hole carbon is mainly hard template method, that is, uses silica, porous metals etc. as template, by immersing carbon source and pyrocarbon
The modes such as change prepare the carbon material of duplication pattern hole structure.Time-consuming, environment for correlation technique there are templates at high cost, technique
The disadvantages such as big are polluted, expanded production is unfavorable for.In addition, existing three-dimensional porous carbon material, generally existing aperture is not easy to control,
The problem of structural stability difference.Therefore, a kind of method for efficiently preparing three-dimensional porous carbon is developed, product is made to have both specific surface area
High, the advantages that pore structure is abundant, stable structure, be bound to can significant increase ionic liquid electrochemical capacitance performance, there is very high reality
Value.
