The invention discloses a treatment method of carbon felt for vanadium batteries, which comprises the following steps: oxidizing and activating carbon felt in 60-100 DEG C sulfuric acid for 0.5-4 hours or oxidizing and activating carbon felt in 20-30 DEG C sulfuric acid for 12-48 hours, and washing with water to obtain the activated carbon felt. Compared with other sulfuric acid or nitric acid oxidization methods, the invention firstly uses an alkaline solution to soak and wash the hydrophobic oil adhesive substances influencing the oxidizing process on the carbon felt surface, and then carries out the sulfuric acid oxidizing treatment, thereby increasing the oxo groups and other hydrophilic groups on the carbon felt molecules and enhancing the hydrophilicity and electrochemically active ion adsorption capacity of the carbon felt. The invention has the advantages of short treatment time and favorable carbon felt activation effect, and enhances the electrochemical activity of the carbon felt and the generation current value of the carbon felt as the vanadium battery electrode.

The invention discloses a method for electrochemical pretreatment on methyl sulcotrione pesticide wastewater. The method comprises the following steps: preparing a titanium-based tin antimony ruthenium cerium oxide electrode by using a coating-thermolysis method, feeding high-concentration methyl sulcotrione wastewater through an electrolytic cell which takes the titanium-based tin antimony ruthenium cerium oxide electrode as an anode, and continuously treating the wastewater for a certain time under certain current density. The titanium-based tin antimony ruthenium cerium oxide electrode is very good in stability, high in oxygen evolution potential and high in catalysis and oxidation capabilities. According to the method, the titanium-based tin antimony ruthenium cerium oxide electrode is adopted to pretreat high-concentration, high-salt and hard-biochemical wastewater generated in the production process of methyl sulcotrione, and the result shows that under conditions of certain pH values, current density and treatment time, the COD removal rate of the methyl sulcotrione can be greater than 50%, the BOD/COD is increased to be greater than 0.3 from less than 0.1, and the biodegradability is greatly improved. The electrochemical oxidation of the titanium-based tin antimony ruthenium cerium oxide electrode is very applicable to pretreatment on biochemical degradation of the high-salt high-concentration wastewater generated in the production of methyl sulcotrione.

The invention discloses a preparation method of an anti-wrinkle battery diaphragm, a battery diaphragm and a battery. The preparation method of the anti-wrinkle battery diaphragm comprises a casting step, a heat treatment step, a stretching step and an internal stress release step. The internal stress release step comprises the sub-steps of standing the whole roll of the diaphragm wound after stretching to release the internal stress, and putting the whole roll of the diaphragm in an oven to release the internal stress again after the standing so as to finally obtain the anti-wrinkle battery diaphragm, wherein the temperature of the oven is 40-120 DEG C, and the treatment time is 4-12 hours. The preparation method of the anti-wrinkle battery diaphragm creatively introduces the internal stress release step into the existing process production, releases the internal stress through standing and re-baking, reduces the deformation of the diaphragm in an electrolyte, reduces wrinkles of thediaphragm after liquid injection, improves the smoothness of the battery and also reduces the adverse effects caused by the wrinkles to the battery, thereby laying a foundation for the preparation ofthe high-quality battery diaphragm and battery.
