PURPOSE:To increase discharge performance by forming a positive active mate rial with a new composite oxide comprising copper-vanadium-molybdenum- oxygen. CONSTITUTION:For example, a test cell for a positive active material has a glass cell 1, a reference electrode 2 formed by pressing a lithium sheet against a nickel expanded metal, a counter electrode 3, and a test electrode 4. The test electrode 4 is formed with the following composite oxide of copper- vanadium-molybdenum-oxygen, Cu0.8V2-yMoyOx (X=5.8-6.0, 0.3<=y<=0.7). One step discharge curve is obtained, discharge capacity is increased, and cycle life is lengthened. |
