With the features of good electrical conductivity, and insolubilization in the electrolytic solution, Poly-Peri-Naphthalene (PPN) can be regarded as the cathode material, and there is a certain necessity to study the electrochemical properties of PPN. PPN can be synthesized easily by 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA), and the related characterizations regarding to PPN is described in this paper. Meanwhile, research on the electrochemical properties of the synthesized PPN under several different temperatures has been carried out, and some basic laws have been found as follows: 1) Under the condition of 600°C≦T≦1100°Csynthesis temperature, the electrical conductivity of PPN is strengthrened with the increased temperature; 2) The discharge capacity of PPN is also increased with the increased synthesis temperature. 3) As a kind of battery cathode active material, the cyclical stability of PPN is excellent. But the capacity is small, aiming at the deficiency, nitrification treatment on the PPN has been carried out, thus the high-capacity PPN is obtained, the first discharge capacity is 342mAhg-1. Therefore, we can safely predict that the future of PPN as a lithium battery cathode material is promising.

Ion Species

A study has been made of surface properties of carbon materials modified by ion beams. Substrates used were natural diamonds, glass-like carbon plates and polymer sheets. Ion species were chemically-active elements such as C, N and O, inert gas elements such as He, Ne and Ar, and metallic elements such as Cr and Ti. It was found that diamond becomes electrically conductive in ion implanted layers, which are amorphous or graphite-like structures. Electrical conductivity depends on implanted species, doses and target temperatures. It was found that glass-like carbon consisting of graphite and disordered graphite becomes amorphous due to ion beam bombardment. Amorphization causes the wear resistance to improve. The electrochemical properties changes depending on implanted species. The wear resistance and electrochemical properties depended on the target temperature during ion implantation. Ion beam bombardment to polymers has been carried out to control the electrical conductivity, cell adhesion and bio-compatibility. The electrical conductivity of polyimide films increases as the dose increases. The saturated sheet resistivity of implanted layers depends on ion species, dose and dose rate. It was found that the cell adhesion can be controlled by ion beam bombardment. The results were used in the fields of clinical examinations. In summary, ion beam bombardment to carbon materials is useful to control the carbon structures and surface properties depending on ion implantation conditions.
