Abstract

[ $LiNiO_2$ ] was mixed with $TiO_2$ or ZnO for the preparation of a cathode. The electrochemical properties of the cathode were investigated and the effects of the addition of $TiO_2$ or ZnO were discussed. The first discharge capacity decreased as the quantity of the added $TiO_2$ or ZnO increased. It is probably due to the decrease in the area of reaction interface according to the increase in the amount of the added oxide. When 2wt.% and 5wt.% of oxides are added, the discharge capacity increased as the number of cycles increased. It is considered that this results from the increase in the area of reaction interface because the oxide is detached from the $LiNiO_2$ with the increase in the number of cycles. The 1wt.% $TiO_2$ or ZnO-added $LiNiO_2$ had a larger first charge capacity than $LiNiO_2$. This is considered to result from the deintercalation of Li ions in the Ni sites along with the Li ions in the Li sites.
