Physical Properties and Chemical Composition of EMD

A or less diam. C, closed pores with no outside opening ----------- superficial surface ---------- true surface 

The ideal battery material should be highly porous, but should have a high density in order to pack as much as possible in to the limited space of the cell. EMD is almost the ideal Mn02 since it is dense and has fine pores (actually cavities).

Table 6 shows the physical properties and chemical composition of typical battery active EMDs, and Table 7 shows a typical chemical analysis of EMD. Figure 14... 

Table 4.6 shows the physical properties and chemical composition of typical battery active HMDs, and Table 4.7 shows a typical chemical analysis of EMD. Figure 4.14 shows a schematic model of an EMD particle showing three types of pores. Figure 4.15 shows the calculated surface area of nonporous solid cubes having a specific gravity (SG) of 1.0, 4.0, and 5.0gmL . As the measured SG of EMD is...
