Sub-micron LiCoO 2 manufactured in a single synthetic step using eutectic self-mixing method

Abstract

Sub-micron LiCoO 2 as a cathode material for lithium rechargeable battery with high rates is easily and economically prepared using eutectic self-mixing method without any artificial mixing procedures of reactants and ultra-miniaturization of products. While the micro-sized LiCoO 2 exhibits the discharge capacities of 134.8 mAh g −1 at 0.1 C and 118.6 mAh g −1 at 5.0 C, those of the sub-micron LiCoO 2 are 137.2 mAh g −1 at 0.1 C and 131.7 mAh g −1 at 5.0 C.
