Abstract
Official abstract text for this publication.
In an aspect, a positive active material for a rechargeable lithium battery including overlithiated layered oxide (OLO), a method of preparing the same, and a positive electrode for a rechargeable lithium battery and a rechargeable lithium battery including the same is disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A positive active material for a rechargeable lithium battery comprising an overlithiated layered oxide (OLO) represented by the following Chemical Formula 2: Li a Ni b Co c Mn d M e O 2-f M′ f Chemical Formula 2 wherein, 1.1<a<1.5, 0<b<1, 0≤c<1, 0<d<1, 0.002≤e≤0.03, 0.03≤f≤0.07 and 0.8≤b+c+d+e<1, M is a cation element of vanadium (V), and M′ is an anion element of fluorine (F), wherein the overlithiated layered oxide has a particle having spherical shape, and the particle has an average particle diameter (D50) of about 2 μm to about 12 μm. 2. A rechargeable lithium battery, comprising a positive electrode comprising the positive active material of claim 1 ; a negative electrode; and an electrolyte.
