Abstract
The invention relates to a method for preparing cathode particles under a co-precipitation reaction by feeding NaOH and metal sulfate solution into different vessels. The invention further provides a cathode active material having the cathode particles. By the method of the invention, the number density distribution of prepared particles is much smaller than feeding NaOH and metal sulfate together into same vessel.
