The present invention relates to a powdered mixed metal hydroxide comprising metal nickel, cobalt and aluminum, which is in the form of powder particles having a core of nickel / cobalt hydroxide and amorphous aluminum hydroxide coated on its surface. The invention also relates to a process for the continuous production of such mixed metal hydroxides by precipitating aluminum hydroxide in the presence of a nickel / cobalt mixed hydroxide in a tubular reactor. The invention also relates to the use of mixed metal hydroxides in the production of active materials for positive electrodes of secondary batteries.n n n n Mixed metal hydroxides, aluminum hydroxide, coprecipitation, nickel / cobalt cores, active materials for secondary battery positive electrode |
