NICKEL HYDROXIDE POSITIVE ELECTRODE MATERIAL EXHIBITING IMPROVED CONDUCTIVITY AND ENGINEERED ACTIVATION ENERGY

摘要

High capacity, long cycle life positive electrode modified nickel hydroxide material for use in an alkaline rechargeable electrochemical cell at least o ne modifier and has modified activation energy, chemical potential and electric al conductivity. Particle size, particle size distribution, electrical conductivity have been controlled by introducing modifier elements throughou t the bulk of the active material and by controlling process parameters.
