Title: Alkali manganese cell
Inventor: OOHIRA TSUKASA
IPC: H01M4/62
Filed: 1982-07-14
Abstract: PURPOSE:To obtain an alkali manganese cell of fixed quality and excellent preservation performance without causing the worsening of molding workability of a positive electrode compound, by using artificial graphite of high purity for the graphite added as a conductive material to the positive electrode compound and adequately arranging specific surface area of the artificial graphite. CONSTITUTION:The invention is characterized by use of artificial graphite in 8-12m<2>/g specific area for the graphite added as a conductive material to a positive electrode. Here if graphite of large ash content as in natural graphite is used, a preservation characteristic is worsened and a drop of open circuit voltage is increased. Because removal of impurity heavy metal is difficult in the natural graphite, it is suitable to use the artificial graphite of high purity, and especially the graphite of ash content being 0.2wt% or less is preferable. Although various kinds are provided as the artificial graphite, molding workability as a positive electrode compound and a preservation characteristic of a cell are largely different in accordance with specific surface area of the graphite.
