Abstract
Provided are uniquely structured electrochemically active particles characterized by a first electrochemically active material and a second electrochemically active material disposed about the first material whereby at least the second material includes a modifier present as a continuous transition concentration gradient from the first material into the second material whereby the concentration is lower in the first material than the second material. Also provided are processes of producing the particle and electrochemical cells incorporating the particles as a positive electrode material in a cathode.
