PRODUCTION OF CD POWDER FOR BATTERY BY ELECTROLYSIS METHOD AND NI-CD BATTERY FORMED BY USING THIS CD POWDER

摘要

PURPOSE:To provide the Cd powder by which an Ni-Cd storage battery improved in battery capacity (AH) equal to or better than an Ni-hydrogen battery is obtd., and the Ni-Cd battery formed by using this Cd powder. CONSTITUTION:The Cd powder is obtd. by using a CdSO4 soln. as an electrolyte and a Cd base metal as an anode, and effecting an electrolysis while maintaining the Cd concn. of this electrolyte at 15 to 35g/liter, pH at 2.0 to 5.0 and temp. at 5 to 60 deg.c.
