Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of forming a high-capacity, high-rate lithium ion battery cathode material, comprising: A) providing a plurality of synthesized electrochemically active plate-shaped nanoparticles; B) adding a plurality of appropriately sized diluent particles to the electrochemically active plate-shaped nanoparticles to form a mixed suspension; C) removing any liquid from the suspension to form a composite material, thereby introducing steric defects betw…
