Cathodic Active Material Composition for Dry Cells, Method for Preparing the Same, and Alkaline Battery |
摘要 |
A cathodic active material comprises a mixture of graphite particles and electrolytic manganese dioxide particles which are composed of needle-like crystals having an aspect ratio ranging from about 2 to about 20 and an alkaline manganese dioxide cell is provided with a cathode prepared from the cathodic active material. The cathodic active material for dry cells can be prepared by mixing, in advance, carbon powder with manganese dioxide powder in a weight ratio ranging from about 1:100 to about 15:100 and then pulverizing the resulting mixture. The novel cathodic active material for dry cells permits substantial improvement of the resulting dry cell in the high load-discharge quality. |
