Title: Methods for preparing materials for lithium ion batteries

Abstract

A process for preparing transition metal particles with a gradient in composition from the core of the particle to the outer layers. In particular, the process involves contacting a first transition metal solution with a second transition metal solution to form a transition metal source solution under specific process conditions. The transition metal particles with desired composition gradients are precipitated from the transition metal source solution. The transition metal particles may be combined with metals such as lithium to form cathode active metal oxides.
