METHOD OF ACTIVE MATERIAL PRODUCTION FOR NEGATIVE ELECTRODE IN ALKALI NI-CD BATTERY

摘要

FIELD: electric engineering. ^ SUBSTANCE: invention relates to electric engineering industry and may be in manufacture of alkali Ni-Cd batteries with pasted or dry-rolled negative electrode. According to the invention, the active material production method for negative electrode in alkali Ni-Cd battery provides for mixing cadmium oxide with and activating agent at the following weight ratio: 0.850.95 of cadmium oxide and 0.50.15 of electrolytic nickel powder as activating agent. The next stage is strong compacting to 1.30.7 g/cm3 and treatment at 270360C in reducing medium. The mixed active material components are heat-treated until loss in weight is 2.04.5% as regard to the initial value and average size of nickel powder particles is from 0.3 to 1.7 mcm. ^ EFFECT: increased specific characteristics. ^ 1 tbl, 5 ex
