The invention provides poly[1,3,5-tri(4-diphenylaminophenyl)
triazine] and a preparation method and an application thereof and has a
structural formula defined as a formula (I). poly[1,3,5-tri(4-diphenylaminophenyl)
triazine] monomers are dissolved in
chloroform;
anhydrous ferric chloride as an
oxidizing agent is added and a full reaction is produced for 10-100 h under
nitrogen protection at a temperature of 20 to 60 DEG C; after the reaction is completed,
methanol is added to make products precipitate, and
filtration is performed; and
vacuum drying is performed to prepare the poly[1,3,5-tri(4-
diphenylamine phenyl)
triazine] represented by the formula (I). The invention also provides the application of the poly[1,3,5-tri(4-diphenylaminophenyl)triazine] as positive pole materials for
lithium ion cells. In the poly[1,3,5-tri(4-diphenylaminophenyl)triazine] and the preparation method and the application thereof, novel conjugated
high polymer material with a certain degree of
porosity and a three-dimensional
network structure is constructed, the
electronic transmission performance of the
anode materials is improved, and compared with the utilization of other materials, the
lithium ion cells utilize the poly[1,3,5-tri(4-diphenylaminophenyl)triazine] as the positive pole materials, so that the
lithium ion cells prepared by the poly[1,3,5-tri(4-diphenylaminophenyl)triazine] have characteristics of superior
cycling stability, a substantial charge-
discharge voltage platform and high charge-
discharge specific capacity.
