preparation example Construction

[0020] 1. Preparation of cadmium hydroxide nanowires:

[0021] Step 1: Take a 1×10cm rectangular pure copper sheet, and use acetone to ultrasonically clean the copper sheet;

[0022] The second step: 10mL of benzene and 50mL of 0.1mol / L cadmium nitrate solution are mixed in a 100ml beaker.

[0023] The third step: Slowly add 10 mL of 0.5 mol / L sodium hydroxide solution to the one-step solution.

[0024] Step 4: Put the beaker in a fume hood, react at room temperature for 48 hours, take out the precipitate, wash it with distilled water first, then with absolute ethanol, and dry it in the air to get the cadmium hydroxide nanowire .

Abstract

The invention provides a method for preparing cadmium hydroxide nanowires. The method comprises the following steps of: 1, performing ultrasonic cleaning on a pure copper sheet by using acetone; 2, putting the cleaned pure copper sheet into a container with a mixed solution of benzene and cadmium nitrate; 3, slowly adding a 0.5mol / L sodium hydroxide solution into the container; and 4, reacting atroom temperature for 48 hours, taking a precipitate out, cleaning by using distilled water and absolute ethanol in turn, and drying in air to obtain the cadmium hydroxide nanowires. The method for synthesizing the cadmium hydroxide nanowires is simple and practicable, low in cost, high in repeatability, mild in preparation conditions and favorable for large-scale industrial production, a surfactant or a template is not used, and products have uniform appearance. The cadmium hydroxide nanowires prepared by the method can greatly improve the capacity of a nickel-cadmium battery.

Description

technical field [0001] The invention relates to a preparation method of a nickel-cadmium battery cathode material. Specifically, it is a method for preparing cadmium hydroxide nanowires mainly used as cathode materials for nickel-cadmium batteries. Background technique [0002] Since the nickel-cadmium battery was invented in the 19th century, it has been widely used in various devices. The advantages of nickel-cadmium batteries are long life, 500 to 1000 charge and discharge cycles, high mechanical strength, good sealing performance, wide operating temperature range (-40 to +50°C), simple use, convenient maintenance, safety and reliability, It can withstand the instantaneous impact of large current (several times or even 10 times higher than the normal use current) without damage, and can keep the voltage very stable for a long time during normal operation. Due to the above advantages, nickel-cadmium batteries have been more widely used. In the past, the preparation meth...
