PURPOSE:To eliminate a falling phenomenon in initial voltage that was a defect of an oxidized copper-lithium battery as well as to set working voltage also to somewhere around 1.5V, by using a positive electrode active material mixing a lower oxide of manganese in oxidized copper. CONSTITUTION:This battery is made up of a positive electrode consisting of a mixture of oxidized copper and a lower oxide of manganese, a negative electrode consisting of alkali metal and an organic electrolyte. Voltage in the discharge initial stage is the higher the larger in a mixed quantity of manganese sesquioxide in design, so that a falling phenomenon at the discharge initial stage is relieved. And, when the mixed quantity of the manganese sesquioxide becomes increased, discharge capacity becomes lessened. From the voltage falling phenomenon and the discharge capacity aforesaid, a proper mixing ratio between the oxidized copper and the lower oxide of manganese is in a range of 90/10-50/50. |
