Embodiment Construction

[0016] A kind of preparation method of electrode material that the present invention proposes, comprises the steps: (1) after the cigarette filter tip that is made by acetate fiber is removed wrapping paper, fully immerse in deionized water (general soaking 2-4 days), ultrasonic cleaning 26- 12 hours, dry and stand-by; (2) put the dried filter tip into vanadium dichloride VCl 2 , lead dichloride PbCl 2 , Tungsten dichloride WCl 2 and nickel dichloride NiCl 2 One of the solutions, or at least two of them mixed in any ratio, the solution concentration is 3wt% to 5wt%, and it is soaked in the above solution for 60-120 minutes in an ultrasonic vibration environment; (3) from the above The filter tip is taken out from the solution, dried, and subjected to high-temperature carbonization treatment to obtain carbonized composite material powder. The carbonized composite material powder is a material that can be used to make electrodes.

Abstract

The invention discloses an electrode and a preparation method of an electrode material. The preparation method of the electrode material includes the steps: putting a dried filter tip into solution of one of vanadium dichloride, lead dichloride, tungsten dichloride and nickel dichloride or solution of at least two of the vanadium dichloride, lead dichloride, tungsten dichloride and nickel dichloride mixed according to an arbitrary proportion, and soaking the dried filter tip in the solution under the circumstance of ultrasonic oscillation for 60-120 minutes; taking out the filter tip from the solution, subjecting the filter tip to drying prior to high temperature carbonization to enable cellulose acetate fibers to form a porous layered carbon material of a micropore structure, respectively generating metallic fine particles and corresponding metallic oxide fine particles, evenly distributing the metallic fine particles and the metallic oxide fine particles in surface micropores of the porous layered carbon material or between folds among layers of the layered carbon material to obtain the carbonized material for making the electrode. The electrode material has excellent electrochemical performance, and is low in cost and beneficial to energy conservation and environmental protection.

Description

technical field [0001] The invention relates to an electrode material, in particular to an electrode and a preparation method of the electrode material. Background technique [0002] A secondary battery is not only capable of converting chemical energy into electrical energy for discharge, but also a battery that can be charged by converting electrical energy into chemical energy by flowing a current in the opposite direction to that of discharge. In recent years, research and development of an aluminum secondary battery using aluminum metal as a negative electrode has been actively carried out. Due to the high ionization tendency of aluminum metal, the electromotive force can be increased compared with conventional batteries using zinc metal as a negative electrode such as manganese batteries, and high voltage and high capacity can be expected. However, in an aluminum battery using ferric chloride as a positive electrode active material, since the ferric chloride is eluted...
