Abstract
In order to be applied to the cathode material in the lithium secondary battery, the characteristics of titanium disulfide TiS2 formed by the reaction of titanium with sulfur vapour has been studied.
The SEM observation showed that the TiS2 crystal formed under a special sulfurization condition had a preferred orientation where a-axis of TiS2 was vertical to titanium substrate. At the X-ray diffraction pattern on its surface the peak of TiS2 (110) was only emphasized.
It was found that the cathode of oriented TiS2 crystal was superior in average potential and stability for charge-discharge cycles compared with the conventional cathode of TiS2 powder, although the discharge capacity was small.
