Abstract
Official abstract text for this publication.
The present invention provides a LiCoO 2 -containing powder comprising LiCoO 2 having a stoichiometric composition via heat treatment of a lithium cobalt oxide and a lithium buffer material to make equilibrium of a lithium chemical potential there between; a lithium buffer material which acts as a Li acceptor or a Li donor to remove or supplement Li-excess or Li-deficiency, coexisting with a stoichiometric lithium metal oxide; and a method for preparing a LiCoO 2 -containing powder. Further, provided is an electrode comprising the above-mentioned LiCoO 2 -containing powder as an active material, and a rechargeable battery comprising the same electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. A LiCoO 2 -containing powder comprising: a co-fired mixture containing a LiCoO 2 and a lithium buffer material, wherein the lithium buffer material is a material of the Formula Li z MO 2 , wherein z is between 0.95 and 1.1; M is Ni 1-x-y Mn x Co y ; y is an amount of up to 0.5; and a ratio of (x/(1−x−y)) is in a range of 0.4 to 1.1, wherein the LiCoO 2 has a stoichiometric composition having a Li:Co ratio of 1:1 via heat treatment of the LiCoO 2 and t…
