Abstract

Official abstract text for this publication.

A method for preparing a layered oxide cathode using a two step calcination procedure, wherein the first step includes pre-calcination utilizing a rotary calciner.

First claim

Opening claim text (preview).

What is claimed is: 1. A process for preparing a layered oxide cathode composition, said process comprising: pre-calcining a lithium source and a mixed metal precursor in a first rotary calciner to form a pre-calcined material; and subjecting said pre-calcined material to high temperature calcination in a second rotary calciner at a temperature of at least about 750° C., wherein the first rotary calciner has at least two zones, wherein each zone has a set temperature throughou…
