Abstract
Official abstract text for this publication.
Provided is a positive electrode for a rechargeable lithium battery including a positive active material including a lithium phosphate compound particle and fiber-type carbon attached inside the lithium phosphate compound particle, a method of preparing the same, and a rechargeable lithium battery including the same.
First claim
Opening claim text (preview).
What is claimed is: 1. A positive active material for a secondary lithium battery comprising lithium phosphate compound particles represented by the following formula: LiFe 1-x M x PO 4 , wherein M is Co, Mn, V, Mg, or a combination thereof, and 0≦x≦0.20; and fiber-type carbon, wherein at least part of the fiber-type carbon is attached to an inside of the lithium phosphate compound particles; wherein the fiber-type carbon has a diameter from about 5 nm to about 25 nm a…
