The invention belongs to the field of a nano functional material and a
new energy source, and relates to a preparation method for an
anode material of a red phosphorous cladding carbon
nano tube composite
ion battery. The preparation method comprises the following steps of: mixing pretreated red phosphorous
powder and a carbon
nano tube according to a certain quality proportion; preparing to a uniform serous liquid with an appropriate amount of a
grinding agent and transferring the uniform serous liquid to a ball
grinding tank; carrying out anaerobic wet high-energy ball
grinding, and thereby obtaining the
anode material of the red
phosphate cladding carbon
nano tube ion battery, wherein effective ball grinding time is 2 to 6 hours. The core of the invention is that the simple and high-efficiency anaerobic wet high-energy ball grinding is adopted to further prepare the
anode material of the red
phosphate cladding carbon nano tube
ion battery; red
phosphate is uniformly coated on the surface of the carbon nano tube, a particular conductive network in the
composite material is built by means of the carbon nano tube, the contact area of the red phosphate and the carbon nano tube is increased, and thus, the anode material of the composite ion battery has the advantages of high specific capacity,
high rate performance and stable circularity; and moreover, the process is simple, the preparation quantity is large, and industrial production is easy to achieve.
