A secondary lithium cell having a cathode containing an activate material comprising a composite oxide containing at least Li and Ni, and an anode of an Li-Ag-Te alloy. The invention is further concerned with a cathode-activate material for a secondary lithium cell comprising a composite oxide represented by a formula LiNiwAlxPyOz (where 0.08 < w < 1.10, 0 < x < 0.015, 0 < y < 0.33, 1.8 ≤ z ≤ 2.2), and secondary lithium cell containing the above cathode-activate material. The secondary lithium cell features large charge/discharge capacity, high energy density, and excellent cyclic characteristics that are deteriorated little after the repetition of charge and discharge. Moreover, the cathode-activate material comprising the composite oxide represented by LiNiwAlxPyOz is inexpensive and easily available. Besides, this secondary lithium cell features large capacity and excellent cyclic characteristics, and can be stably produced at a low cost. <IMAGE> |
