MANUFACTURE OF POSITIVE ELECTRODE FOR ORGANIC ELECTROLYTE BATTERY

摘要

PURPOSE:To obtain a positive active mass which provides desired discharge voltage and discharge capacity by making a complex oxide in such a way that the mixture of copper nitrate and bismuth nitrate is heated under an oxidizing atmosphere. CONSTITUTION:Bismuth nitrate Bi(NO3)3.5H2O and copper nitrate Cu(NO3)2 or Cu(NO3)2.3H2O are mixed in an arbitrary ratio. This mixture is heated under an oxidizing atmosphere to obtain a complex oxide having the general formula of BixCuyO3x/2+y (X, Y=1-6). This compound is used as a positive active mass of a positive electrode with an organic electrolyte. By selecting the ratio of Bi and Cu in the positive active mass and assembling this mass with a negative electrode using a light metal as a negative active mass, an organic electrolyte battery having desired discharge voltage and discharge capacity can be obtained.
