Abstract

The invention discloses a method for producing novel energy storage material with organic dye waste and application of the method; nitrogen-bearing dye MB (methylene blue) and anthraquinone dye ARS (alizarin red S) are used as raw materials, mesoporous carbon (CMK-3) is used as an adsorbent, and MB / CMK-3 and ARS / CMK-3 composite electrode material is prepared and is applied to cathode materials for lithium-ion batteries and other batteries, and capacitors. The method comprises the specific steps of (1) dissolving organic dye waste to obtain waste liquid; (2) extracting organic dye from the waste liquid; (3) combining the organic dye with a double-electrode-layer capacitor active material to obtain a composite electrode; (4) fitting the composite electrode in an energy storage device. The method has simple preparation process and good repeatability; the raw materials have rich reserves and low cost; the common organic dye waste in sewage is used as an active material for energy storage materials, environmental pollution can be relieved, and construction of the novel energy storage material is achieved; in addition, the prepared composite electrode has high specific capacity and good circulating performance.

Description

technical field [0001] The invention relates to the technical field of energy storage materials, and more specifically relates to a method for making new energy storage materials from organic dye waste and its application.
