Abstract
A method is provided for forming a high-capacity, high-rate lithium ion battery cathode material. The method includes providing a synthesized material of electrochemically active plate-shaped nanoparticles and adding a plurality of appropriately sized diluent particles to the plate-shaped nanoparticles to form a suspension. Any liquid is removed from the solution to form a composite material. The method also includes processing the composite material to form a high-capacity, high-rate lithium ion battery cathode material.
