摘要:
A separator for alkali-zinc battery comprising a microporous membrane having alkali resistance, a part of the porous membrane having highly persistent hydrophillic property and the remaining part having water repellent property. In the part having hydrophillic property, precipitation of ZnO can be controlled sufficiently because of its large persistency of hydrophilic property so that dendrite short-circuiting in the battery can be prevented satisfactorily. In the part having water repellent property, O.sub.2 gas is permeable well through it so that a decrease in capacity of battery can be avoided.

摘要:
A method for forming a nickel plate or a method for making up an alkaline battery, in such a way that cobalt oxyhydroxide is previously formed on surfaces of positive active material powder and used therefor, by mixing the positive active material powder with CoO powder, for example, to be oxidized, by oxidizing the positive active material powder in a solution including cobalt ions, or by mixing the positive active material powder with cobalt oxyhydroxide powder. A conductive network comprising the cobalt oxyhydroxide is formed, so that conductive efficiencies between the positive active materials and the positive active material and the substrate are made better.
摘要:
A negative active material is characterized by being prepared by adding a lignin having a unit structure represented by the formula (I) as the main structure to a lead oxide. Since the lignin of the formula (I) is added, the negative active material can be prevented from shrinkage due to charge/discharge. (wherein R1 is H, OH, COOH, SO3H, SH, C6H5, COO−, SO3−, R2C6H4, (R2)2C6H3, or (R2)3C6H2; and R2 is at least one member selected from among OH, COOR, SO3H, and CH2SO3H.)
