摘要（英）：

The invention relates to application of rice-husk-based activated carbon materials to an asymmetric electrochemical supercapacitor, belongs to the technical field of chemical power sources, and aims to provide an asymmetric electrochemical supercapacitor on the basis of rice-husk-based activated carbon. The asymmetric electrochemical supercapacitor comprises a positive pole, a negative pole, a diaphragm, electrolyte, a positive lead, a negative lead and a shell. The positive pole or the negative pole of the asymmetric electrochemical supercapacitor contains the rice-husk-based activated carbon which is used as an activated substance, the pole containing the rice-husk-based activated carbon is used for implementing an electric double-layer energy storage principle, the other pole is a pseudo-capacitive pole or battery pole, and the electrolyte is aqueous electrolyte or organic electrolyte. The asymmetric electrochemical supercapacitor has the advantages that the electric double-layer energy storage pole of the asymmetric electrochemical supercapacitor is made of the rice-husk-based activated carbon which has wide raw material sources and is advantageous in terms of price, accordingly, the cost of the electrochemical supercapacitor can be lowered, and the application range of the rice-husk-based activated carbon which is made of agricultural waste is broadened.
