Embodiment Construction

[0010] Activated carbon is a material which has a high surface area and which is mainly used in the adsorption process and is generally in powder / granule form. In electrosorption applications, activated carbon is used as an electrode. If activated carbon is used as an electrode, it must have a monolithic structure. In the conventional method of making monolithic activated carbon, when activated carbon particles are combined, the surface area of ​​the activated carbon is reduced. The reduction in the surface area of ​​the activated carbon results in a decrease in efficiency in applications where the activated carbon is used as an electrode. Thus, with the present invention, there is provided a method of making an electrode comprising activated carbon particles and having a high surface area.

[0011] The production method according to the invention comprises the steps of mixing 5-90% by weight (preferably 85%) of activated carbon granules and 5-90% by weight (preferably 15%) ...

Abstract

The invention discloses a production method. With the present invention, there is provided a production method for an electrode comprising activated carbon. Said production method comprises the stepsof mixing 5- 90% by weight of activated carbon granules with a 5-90% by weight of a thermoplastic powder; adding 3-10% by weight of water to the said mixture; heating the aqueous mixture to 135-145 DEG C; stirring the heated mixture at the said temperature for a predetermined period of time; pouring the hot mixture into a mold and pressing it at a pressure of 500-2000 bar so as to produce an electrode; removing the produced electrode from the mold so as to allow it to cool down.

Description

technical field [0001] The present invention relates to a method of making electrodes for electrosorption applications comprising granular activated carbon. Background technique [0002] Activated carbon is an economical material obtained by pyrolysis of organic substances at high temperatures and has a very high surface area as well as being electrically conductive. Activated carbon is mainly produced in powder or granular form. Activated carbon can be used as an electrode in electrosorption (electrosorption) processes, for sewage treatment or charge storage (ie, in capacitors). Electrosorption is generally defined as current- or potential-induced adsorption on the surface of a charged solid. Charge with very low current (0.5-2.0mA) or potential (0.5-1.5V). The capacity of electrosorption depends on the electrochemical surface area and conductivity of the materials used as electrodes. Activated carbons, on the other hand, can be used in electrosorption applications only...
