Abstract
Triphenylamine as well as its polymer have been applied in the fields of photoelectricity and energy storage. In this paper, the pyridine ring structure was introduced into the triphenylamine structure to successfully synthesize N, N-diphenyl-4-amine monomer (DPN), and the its single crystal was then cultured. And its homopolymer (PDPN) was further prepared by chemicaloxidation method. The obtained poly (triphenylamine) derivative-PDPN was used as cathode material to study its electrochemical and battery performance. As the result, the chemical structure of the monomer was confirmed by NMR, MS and single crstal analysis. And the chemical structure of PDPN was confirmed by infrared spectroscopy and ultraviolet spectroscopy. Furthermore, the battery performance test shows that PDPN electrode has two obvious voltage platforms in the voltage range of 4.1-4.3 V and 1.5-1.8 V, in which the initial discharge specific capacity was 92.3 mAh·g-1. After 50 cycles, its discharge specific capacity decreased from 92.3 mAh·g-1 to 73.2 mAh·g-1 with about 20.7% capacity loss.
