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